  1. Do you just use a jack converter to make it a normal earbud size? Is the output about right? I much prefer earbuds so i can choose my headgear without worring about the headset going over the top.
  2. I had been running my threshold setting at 7 to get the slight hum in my phones and it finally dawned on me this is not an optimum setting for picking up deeper fainter signals since a setting closer to 0 should be best. Having always ran the detector volume control in the upper ranges and using the headphones to control the audio level, I decided to switch it around by setting the headphones to max and using the detectors volume control to set the overall audio level. This made a huge difference, now I can get that same slight hum with a threshold setting of 2. Subjectively there seems to be much less modulation on the deeper targets where now coins in the 10"+ range are much louder hits. I'm also running the detector volume control at 4 to 5 to get the same audio volume I was getting before with it set in the mid 20's. Tom OK so I decided to do some air tests to see what difference there is in audio modulation and on coin size targets there is a difference in audio the last few inches. First number is a full audio report distance (or as close as my ears perceive it), second number is the distance target lost. The difference between is the amount of audio modulation where the target volume decreases to the point the signal is lost. The first column is with the headphone volume at max and threshold audible at 1 setting (0 is silent), second column is detector volume at max with threshold at 7 (6 silent) Headphones max......................-... Detector max dime............. .............9" /10" ...- ..7" / 10" Buff nickel......9-1/2" / 10-1/2" ...-.. 8" / 10-1/2" IH penney..........10" / 10-1/2"....-....9" / 10-1/2" As we see there is no difference in detection distance between the 2 settings but a more modulated audio response with the detector volume at max. I also tried the dime with the detector volume at max with a 0 threshold setting and the results were a full volume report to 6" with a max detectable distance of 9", for a 1" loss. Because of this it is apparent that ML has designed the threshold level to follow the volume setting (7 equals 1) which would allow max sensitivity when the detector is used without headphones in cases where a high volume setting is needed to overcome ambient noise. The loss of response on the dime indicating a negative threshold setting because at this volume setting 6 is actually zero. Since these were coin sized targets and not tiny nuggets the difference could be even bigger when nugget hunting.
  3. That was some fantastic advice & info that every gold detectorist needs to watch. Thank you Steve for putting that up.They put it across in such an easy & simple to understand manner. The VOICE of the detector (threshold). What a great way to put it across because that is exactly what the threshold is. The voice of your detector talking to you, telling you what it is "seeing" & why it is so very important to get that "voice" as stable & smooth as possible through ground balance, sensitivity settings & soil timings. One thing they emphasized near the start was using head phones. There was no mention of boosted external speakers..... So I would like to ask the question...... What are your guys thoughts on head phones versus boosted external speaker set ups & why & what do you prefer & think works best for you? Here are my thoughts & what I use now. When I first started gold detecting back with my GP 3000 I was a head phone user. I went from that to boosted/amplified head phones. I tried external speakers but just didnt like them. I liked being locked in to my own world with the head phones. No out side noise influences. Just the sound (voice) of what my detector was telling me. I found I was able to focus & concentrate so much more with out out side influences. Mentally ground balanced to what the "voice" was telling me. For quite a few years I was happy operating this way. When Mrs JW came out detecting she was not going to wear head phones. So I rigged up an external speaker through a booster for her. That put me off them even more as every time Mrs JW got a signal I would hear it half a mile away. WHAT THE HELL, I would think.It just sounded so out of place out there up in the peace & quiet of the hills & open country. I just couldn't get my head around why any body would want to use an external speaker, especially through a booster. But over time I noticed a few detector operators that I hold in high regard & who were finding good amounts of gold, were using external speakers through a booster system. Now I am not the sharpest tool in the shed, a tool maybe , but not the sharpest. I thought....there must be something in these external speaker/booster systems that these people know that I haven't cottoned on to yet. So one weekend I went out detecting & I deliberately left my head phones at home so I had no choice but to use the external speakers & booster all weekend. Well...the rest is history. I dont even know what it really was to be honest. But something just seemed to click with in me with the external speakers & booster system. I havnt used head phones ever since except on the 2300 & that is because I havnt got the 1/4" head phone adapter that I could run my booster system through. Only if it is blowing an absolute gale will I consider head phones. Thats me, what are your thoughts. Cheers. Good luck out there JW
  4. JW - I've been running WM12/Booster/Headphones for the last few months. (recently adding JP's booster) I like this and have tested this against the setup without the booster and did not notice much difference. I enjoy using the booster more as a volume control as adjusting headphone volume is a pain.
  5. Hi all, I just picked up a Pro-Sonic wireless system from Rob and am eager to hear what you all have to say about a headphone recommendation for it, I've always hated the Koss OEM GPX headphones but am torn between something like a Ghost two ear coverage or a Rattler with one ear for use in snake country. Have any of you used the Rattler one sided headphones and were they worth the reduced hearing or should I go two phone coverage? Thanks all Jen
  6. Hi Forum Members , I have just read an old 2015 thread regarding wireless headphones , Vanursepaul purchased TDK , wireless guy explained kleer technology and tvanwho mentioned the transmitter with the RS160's plugged in wall . Wish to know if this transmitter will connect to SDC2300 battery and if so what size is it . Cheers goldrat
  7. Just back from Colorado and have enough experience with the deteknix W3 Lite model to relate my impressions. Keep in mind I'm just a buyer/user with limited (compared to many of you) experience. Since getting home I noticed they've added two new models to their line: They now offer large, what appear to be over-ear headphones (designated 'Pro' in their listing) to the on-ear (now designated 'Lite') models that have been available for several months. Just to summarize, the six models are W6 Pro (6 mm plug with large headphones) WA Pro (Garrett waterproof connector w/large hp's), W3 Lite (3 mm plug, small hp's) W6 lite (same as previous except 6 mm plug) WA lite (same as previous except Garrett connector) and WR lite (3 mm male for transmitter connection, 6 mm female for receiver to headphone connection). I have the W3 Lite model for which I paid a bit under $90. My model actually came with a 1/4 in (6 mm) male to 1/8 in (3 mm) female adapter/connector. I'm going to break this review into two parts since that seems to be appropriate given the two approaches -- you supply the headphones vs. they supply. 1) General usage: Obviously these are wireless headphones and as such represent that technology/ergonomics to the user. This is why I got them (hate dragging my detector around when it is tethered to my head!). They certainly accomplish that goal. I've been as far away as 10 meters (> 30 ft) from my detector without loss of signal. The transmitter (about the size of two matchboxes oriented end-to-end) is connected to your detector by (default) a custom rubber band which is actually an O-ring. This is OK, but "in the wilds" where you're bumping into rocks, trees, etc. it can come loose. I recommend velcro attachment -- an 'aftermarket' mod which looks pretty easy based on a YouTube video I've seen. (Quite a few YouTube video reviews of these, BTW.) I'll be making this mod with mine soon. As far as lost connections, my experience over an integrated 15+ hours of use is that it isn't a problem. I noticed what appeared to be a skip in T/R maybe four times, all within about 2 hours, and each lasting less than 1 sec. It is possible my plugs (I was using a 1/4 male to 1/8 male adapter which came with my unit so total of 2 connections) weren't completely inserted during that session. Even if this were to be systematic issue (which I doubt), I can't see how it could be an issue given its infrequency. BTW, I mostly use mine in all metal mode with a constant audio sound above threshold. But when I did run my detector in silent discriminate mode they never shut down (power saving?) as I've read that some other brands of headphones have done. Battery life: The longest time I used these without recharging was ~6 1/2 hours and they didn't run out of juice, so I don't know the limit. Each component has an LED which shines when the unit is on. If I'm taking a long break (e.g. lunch) I turn both off to save the batteries. It took about two hours to recharge after that session from my laptop computer -- that was the headphone/receiver recharge time. The transmitter recharged in less than 1/2 hour. Regarding recharging, the unit comes with two DIFFERENT cables. Both have the 'standard' USB (12 mm X 4.5 mm) connectors at one end for plugging into your computer or automobile console (for newer model vehicles) but different micro-USB connectors for the transmitter and headphone (receiver within) connections. The purchased package does not include an AC wall socket to microUSB assembly like you typically get with cellphones, but I'm sure you can find/buy these. The two microUSB standards here are common as I have cellphones (current and past) which use these connectors. 2) Choice of headphones: As mentioned, I have the 'Lite' on-ear version which I'll review below. However, if you have a set of headphones (or more :) which you really like then I would suggest the WR model where you can put the receiver on your person and have the chord attaching there. You are still detached from your detector. And I have no idea how the new 'Pro' headphone models from deteknix perform. (From their website it looks like the retail cost net difference between Lite and Pro is $60.) Hopefully there will soon be or already are reviews online somewhere of these. 3) 'Lite' on-ear headphone performance: Basically these look like not-so-expensive music audio headphones you might see teenagers (or old farts, for that matter) wearing walking down the street. They even have what appear to be pause/play and fast-forward/rewind buttons on them which, AFAIK, have no use when used with a metal detector. The on/off and volume controls on the headphones do work with MD's. These are almost completely plastic (there is a steel band running through the overhead structure) which probably makes them susceptible to breakage for hard-core detectorists, especially in hot desert environments. They are small enough to fit under my full rim flyfishing hat. However, I tried putting them over a baseball cap and then I wished the extension arms would have gone out a bit more. (I don't think I have an unusually large head, well, not literally but maybe figuratively... :). Regarding sound quality, I found them quite usable/agreeable. I never got into extremely noisy environments (e.g. heavy auto traffic or raging/rushing water) but they did fine in the wind. Again I expect these perform similar to typical on-ear headpones. As far as comfort goes, I didn't notice them over the four hours of my longest non-stop session, so for me, no problems there. Overall I'm pleased with my purchase. I realize there are other options, but AFAI can tell those are more expensive (in some cases much more expensive), and for my demands/requirements these fit-the-bill at an affordable price.
  8. i was at the pleasonton gpaa gold show yesterday and got my hands on a pro-sonic. there price is $269 and they said they shipped them out to all the vendors on friday so everyone that wants one should be able to get one shortly.
  9. I seen they are available now on the Garrett website . I ordered one from . Im looking forward to trying this one out and cuttin the cord.
  10. I was looking over on Chris Gholson forum and he's got the new Garrett Z-Lynk for 127.46 with free shipping. He is also putting your name in the pot if would like the new Minelab Pro Sonic for 269.00 plus free shipping. I'm just wondering if the one that has a higher price that much better than the other ? I know Minelab puts out a great product and as far as I know always has. But is the added 141.54 better than the American made one. I can't go out and buy both to find the answer to my question so I hope over time you can. Chuck
  11. Hi guys, Mrs JW & I had spent most of Thursday doing some landscaping out the front of our place. We went down to the Shotover River & got some big slabs of schist for some path way stepping stones & did some tussock grass plantings. We had finished by about 3pm. Mrs JW said, "Do you want to go to ........ & do some detecting?" I hadnt been there for about 18 months due to not being able to get any more gold out of there so I sort of umed & arred....not sounding too keen on it. I was a bit knacked from wrestling with the slabs of schist & digging them in to place. "You havnt tried the Zed there have you?" No I havnt I said.....still not too keen. "I just want to get out of here & it is a nice place to be." she said. I couldnt argue with that so off we went. The last time I had been here so had someone else before me & had left big un filled holes. I was really pist off with that & the holes were still there. I pointed them out to Mrs JW. Oh...they are big she said. Not holding my breath I rigged up & got in to it. This area has had all the overburden ground sluiced off from the oldtimers right down to schist bed rock. I had done well here back with the 3000, 4500, GMT & GB2 until I was getting no more. Not 1 minute in to it & I backed up on what I thought was a very very faint signal on top of the schist bed rock. Well I'll be buggered. It was repetitive with each sweep. All be it ever so faint. Probably a lead pellet. Bit of a scrape of the top & it improved but was still in the schist. Down now in to the schist & getting deeper & better. Down in to a small deeper crevice in the schist. How small is that. You can just see it on the coil in the above pic. What gobsmacked me was the depth for such a small piece. A few minutes later. Another very very faint signal. Exactly the same scenario. Down in to a deeper schist crevice Then another faint signal & down in to the schist wash. Wasnt in a crevice or schist bed rock but down a wee bit. Still bloody small. Then it dawned on me that I hadnt got one crap target. Just gold gold gold. One after the other. Shows how heavily this ground has been detected. No crap signals left. I then wondered over to one of the unfilled dig holes & waved the coil in to it & around the outside. What was that?? A signal. I backed up & on the top outside edge of the hole was a definite signal. I scraped away at it & it was still there Gold it was. Another very small bit. You may just make it out beside the G on the coil. If you go... I walked back towards where Mrs JW was sitting waving the coil as I went ready to pack up & head off when I saw another shallow scrape from some one else in to the up on edge schist bed rock. Ha....they must have got a wee thin bit stuck in the on edge folds of schist. And as I do..... I waved the coil over there scrape. Well I'll be darned....a faint signal. Must me another thin piece jambed in there some where. They cant have re scanned there dig after recovering their target before moving on. BIG mistake. Well to cut a long dig short. It wasnt a shallow bit & I ended up having to smash in to the solid schist rock. No way I thought. Felt the pain for my pick....not to mention me trying to dig the bugger. Mrs JW was pissing herself with all the grunting & groaning coming from me. You may have to come back for it, she said. No way I said. This is going to be gold & I aint leaving it here. It still wasnt out at this stage. Look at all that smashed out schist. poor pick Oh well....back in to it Look at the depth in to that soild schist & Mrs JW having a good my exspense Finally it was out Ended up with 6 bits for .88 of a gram Now I realised that on my very first day with the Zed that there was something very special about this detector. For me it was the depth it was getting small gold at. I realized that any bigger gold would take care of its self. I cant fathom why there was so much bagging of this detector from so many when it first came out. I can only put it down to people being so stuck in their detecting habbit ways with the PI's. The Zed is a different beast & needs to be used as such. I guess I am lucky that & a bit of water has flowed under the bridge since its release & learning curves been learned & I have benefited from that. One thing that really stands out for me is from what JP said. Be conservative with your settings. When I first used it I had the threshold up a bit & the sensitivity to the point where it was running a little bit ratty. Just like I did with the 3000 & 4500. Getting that top end max out of it. The thing with the Zed is the faintest of signals still lift with the thing toned down a bit & so getting rid of that Zed warble, especially with JP's B&Z Booster system. The swing arm helps immensely too. I wouldnt be with out it to get that total coil swing control. Even & parallel to the ground. Mrs JW & I did go out yesterday for a detect with a bit of success. We are in for a few crap weather days so this will be my last report for 2016. Will do yesterdays outing in the new Year. Cheers guys. All the best to you all for 2017 Happy New Year JW
  12. A new Treasure Talk blog from JP
  13. Here is all the latest along with the new instructional video.... Video Review... Specifications and pricing....
  14. I couldn’t find a wireless delay specification for the GPZ 7000 WM 12. So I tested it. The attached oscilloscope display is the audio waveform envelopes from a US nickel passing over the GPZ-19 coil at approximately 40 inches per/sec. The upper yellow waveform is from the earphone jack on the back of the GPZ 7000. The lower green waveform is from the earphone jack of the wireless WM 12 receiver. The waveforms are sweeping in time from the left side to the right side. The entire display is divided into 10 horizontal increments of 50 milliseconds (0.050 sec.) each. The audio (wah-wee sound) created by the nickel is spread across 9 divisions (450 milliseconds) with the nickel crossing the center of the coil at approximately 4.5 divisions (225 milliseconds). Close measurement of the green trace displacement to the right indicates that the wireless WM 12 receiver audio is delayed by 20 milliseconds. The nickel speed of 40 inches per second is equal to 1 second divided by 40 = 0.025 sec. = 25 milliseconds to move 1 inch. So a delay of 20 milliseconds is less than a 1 inch position error which would be imperceptible during normal searching. When slowed down to pinpointing speed it would be a minuscule error. A 50 ms delay would result in an approximate 2 inch position error which at sweep speed is probably not that noticeable to most of us. Again at pinpointing speed it should not be a problem. For information; the scattered positive and negative spikes are noise spikes from the GPZ 7000 transmitter pulses. The wide bandwidth / fidelity of the oscilloscope allow it to capture these spikes. The spikes are too high in frequency for the human ear to hear. Electromagnetic Interference (EMI) that we randomly hear resembles the waveform envelopes shown in this display. This is somewhat technical so I hope I have made it understandable to some. Have a good day, Chet
  15. I have often wondered if the detector itself is more sensitive than the speakers that it has and even though the signal is there we don`t hear it. Perhaps a speaker with some kind of a meter that would indicate we are passing over a target even though the speaker is silent I`m sure there are meters that could indicate the presence of such signals, perhaps big gold at more depth?
  16. Is there a trouble shooting guide on line for the B and Z booster? When I left home, it was working now I can't make it work. New batteries didn't help. only time sound comes out is in bypass. Any help would be greatly appreciated. Thanks Norm

  18. I plan to try the Minelab PRO-SONIC on my SDC 2300. Would there be any advantage to adding a BZ Booster into the equation or not necessary?
  19. This setup works great and there's no headphone wires at all! Sound quality is good, head phones are light and comfy, i had to bend them to fit my small head, I usually got to find a happy medium with the volume on the headset and volume on the gold screamer. Be sure if you get make sure it's the low latency headphones cause there is two different on the link I posted. The right wire took me awhile to find, before I had to two peace it and I don't like having to many connections. I also got a secondary transmitter so I can use regular headphones or just as a back up.

  20. Makro dealers are now taking pre-orders for the new 2.4 GHz wireless headphones and transmitter module for the Gold Racer and Racer 2. They will start shipping dealers in June. MSRP: $119 PLEASE NOTE THAT THE NEW 2.4 GHz HEADPHONE OPTION IS NOT COMPATIBLE WITH THE RACER AND WILL ONLY WORK WITH THE GOLD RACER & RACER 2 MODELS. This is the last picture that was available but the actual shipping units may vary in appearance.
  21. Garrett News Release - Lightning-Fast Garrett Z-LinkTM Wireless Technology As announced earlier this year, Garrett will soon be rolling out wireless technology. The first introduction, to be formally announced later this fall, will be a Wireless Transmitter/Receiver Kit that will work with virtually any brand of metal detector and/or headphone combination. These wireless modules will employ unique Garrett Z-Link Wireless Technology providing a near-zero delay time between the detector and headphones. The Garrett units will operate six times faster than Bluetooth (the speed claimed by some current wireless transmitter kits). This means you are hearing the target signal while the searchcoil is directly over the target, helping you to pinpoint and recovery your targets more accurately, The new Wireless Transmitter/Receiver Kits can be ordered with either a 1/4-inch headphone jack cable (PN: 1627100) or a Garrett 2-pin AT connector cable (PN: 1627110, for use on AT Pro, AT Gold, or ATX units). The transmitter and receiver modules can be recharged with the supplied USB cables by attaching them to your laptop, your vehicle's USB port, or to a phone charger's USB power block. When fully charged, the units will provide up to 30 hours of operation-significantly longer field time than offered by other wireless models. More product information, including pricing will be announced later. Seen below is one of the Wireless Transmitter/Receiver Kits. Following the release of the new Garrett Wireless Transmitter/Receiver Kit, the Garrett Z-Link Wireless Technology will be implemented into future metal detectors and headphones. One of the products sure to create attention will be a new All-Terrain (AT) product that is slated for a spring 2017 release. Just like the current AT Pro, AT Gold, ATX, and Pro-Pointer AT, this new machine will maintain its waterproof integrity while adding exciting new features, including built-in Garrett Z-Link Wireless Technology for headphones. More specific details on this detector and other wireless accessories will be made available in early 2017.
  22. I've been running the GPZ, here in Yuma by the Sea, with the In Ear Monitors (Etymotic)+ 75 ohm Impedance adapter + mini stereo amp. My settings have been HY, Normal, Sens of 20, Low Smoothing. The main difference for the past 2 weeks has been full stop minimum Threshold. What I have found is that with more volume from the mini amp, I am hearing everything the machine has to offer with no threshold. Mind you, this is all pretty quiet ground and I really make an effort to avoid the trashy areas. Occasionally I hit the zones of red clay and the machine will heehaw to beat the band. No bueno for these settings. I end up running Difficult in those clay zones. As you can see from the the photos (past 2 mornings), I am finding some really tiny gold. All I can say is without threshold, the Z's background chatter smooths to a hum over tiny gold. They're a bugger to recover and I've walked away from quite a few that I just couldn't get into the scoop. They are obviously so small that it's not worth the effort. The big ones take care of themselves. The 6 gram piece was down about 14 inches on a small terrace above the normal dry desert wash. This system is working for me because with 0 threshold I'm not bombarding my hearing with constant noise. The Ety's are super noise isolating so I am hearing all changes in the background chatter of the Z. The down side is I will have trouble hearing that Lion or rattlesnake if he gets after me. Well, until that becomes a problem I'll stick to what's working.
  23. Disclaimer: My testing is not rigorous nor scientific in any way. Individual hearing is highly subjective and what works for me may not work for you. As always your mileage may vary. Detector: Minelab 7000 - HY, Normal, Sens 20, Volume max Earphones: Etymotic 4s 100 ohm impedance Adapter: APureSound 75 ohm impedance 1/4 inch headphone jack conversion to 1/8 earphone jack. Amplifier: FiiO A3 I have always used the Ety earphones in all my previous GPX detectors. Headphones are just too hot and cumbersome for me. The Ety's are top of the line In Ear Monitors with balanced armatures. Ety was primarily a hearing aid manufacturer and got into the earphone market for high end earphones. The 4s cost in the neighborhood of $300.00. Their 3 flange silicone ear piece is super noise isolating, but not particularly comfortable. If you are worried about hearing snakes, cougars, bears and such, you won't like this much noise isolation. Until I went out with Lucky Lundy I was very happy with using the WM12 external speaker for all my detecting. But after seeing his results with really good headphones, I was convinced I was missing some of the super faint targets. I switched to another brand of earphone while I was out there at Rye Patch and was getting decent results but the audio was harsh giving me more of an audio fatigue. So, for the past couple days I've been playing around with different audio setups trying to find a good balance. After locating a few undug faint targets, I switched back and forth between audio setups over these targets. My results were interesting but not particularly life changing. Adding 75 ohms of impedance bringing my total impedance to 175 lowered the available volume sufficiently for my 62 yr old impaired hearing that I added the mini music amplifier to give me more volume. My unscientific impression of adding more impedance felt like adding audio "smoothing". The audio seemed a little more stable and less jittery. Again, I switched back and forth over the same targets adding impedance and then without it. I even switched between the wireless WM12 and a direct connection to the detector, which did not seem to make any difference in the quality of the tone. I also ran Beats sports earphones with 27 ohms impedance. The audio sounded really harsh with too much uncomfortable scratchy highs. Adding the impedance made them tolerable, but not great. Results: Running 175 ohms impedance produced a smoother, more stable background but lowered audio volume. The most significant thing I found in my testing was playing around with the Threshold. I had been running Threshold at low 30's with the external speaker, but with the earphones that's just too much "noise" too close to the earbones. With these In Ear setups I found that I could run the Threshold at 0 and get perfectly identifiable target tones over these tiny, tiny targets. The best I can describe it is the detector has a rhythm of background beeps and bleeps, but over a tiny target the beeps stretch into a faint hum. A good target will come through loud and clear without any confusion. My target results are impressive. The smallest nugget is .09 gram. I found all these over the past 2 mornings in ground that I've been over dozens of times. I am certain that the earphones with their noise isolation improved my results, but adding the impedance probably just made the audio a little more comfortable. Bottom line, good aftermarket headphones already have between 100 and 200 ohms of impedance. Frankly, I don't think adding more than that will produce much benefit. Adding the mini amp helped me, especially running with 0 Threshold.
  24. I have a ML GPX 4500 and want to buy a control box cover that has a battery pocket. So, I need a shorter power cord...any idea where to get one (and ensure it meets specs)?? And, any suggestions on the best headphones? ...Killer Bee Wasp?
