  1. Hi Folks, First Post on any site,first metal detector. Reaching out to the more experienced detectorists to ask if anyone has seen or heard of problems with the Nokta Simplex +. Last August I purchased my first detector ,a Nokta Simplex. The Battery was at 3 bars ,half charge, when taken out of the box. My job of 140 hours a week, never allowed me to go detecting once last Summer. I put the detector in the closet . Yesterday I got it out to look it over and charge it and it still had 3 bars. I properly connected the charging cord and charged it 3 hours. It still only had 3 bars. So I tur
  2. Just now reading Ridge Runner's contest (I know , it's over!), I noticed some comments mentioned looking for one....... I live in my RV so inverters (and solar) are in my wheelhouse ARRRRRRRRRRRRRRRR ! I am partial to the pure sine wave (PSW) type as the sensitive electronics like computers (or a Nox) , are often a bit "gun shy" around the modified sine wave (MSW) units. I just got a Renogy 700watt PSW inverter last summer and am very impressed with it. ANNNND My Nox seems to like it too. A bit more power than the prize unit but it will charge two detectors including head
  3. I have been married two times and it’s been a long time.haha To win this inverter tell me the total number of years to both wives. Please only one guess for each person. I’ll stop the contest on 3/17/18 6PM CST and the nearest guess without going over is the winner. If someone gets it correct sooner I’ll stop it then. Chuck PS Has one USB port
  4. Whites 5900 Di SL Pro Need a way to power the unit, New adventure.. , but I would rather copy What options do I have? (Welcome to suggestions) What can I replace the "C" holder with? For instance, moving the 4.5 volt power pack to a waist belt and cable system, using a 1/8" phono/headphone jack to quick disconnect. Or perhaps a rechargeable battery pack that can be plugged into a charger without removing. Has anyone designed a battery system that is fairly quick and easy? (and perhaps even lighter than 4 "C size batteries) Sub "C" or Dou
  5. Got sick of buying 9v batteries for my Profind pp. Blackube just came out with rechargeable 9v lithium batters that have the same voltage as an alkaline. A little pricey at $25 for 2 but the PP no longer falses out when put on it's side then turned back up. This used to drive me crazy. Batteries put out near full power until they run out instead of fading in power like alkalines do. IMO worth the few extra bucks.
  6. Curious to your thoughts on the LiPo batteries contained within the Nokta machines. They (Lithium Polymer batteries) are a wild breed in many formats and within the RC community tales of exploding fire batteries are not uncommon. They have special regulations regarding transport/shipment (especially within aircraft) and I've read they can be extremely fickle in regards to charging/storage. I'm only looking for input on the batteries themselves. The product line is amazing and what you get for the price is impressive (SIMPLEX!) and not in question. Hope everyone is well! -Bryan
  7. I took a Fatshark battery pack that holds two 18650 li-ion cells and fed it into a buck converter adjusted to 6.86V output and used it to power my GP Extreme. I'm testing out a (TDI) Beach Hog coil at the beach. I have a Barrie Johnson Nuggettfinder MKII that has its own speaker/amp as well as speaker/phones volume controls. The buck converter has less than a volt dropout so it has a reasonable life of about an hour and a half. I did run into a problem though - if the coil got too near my scoop the detector overloaded. Something, the audio amp, the detector, I don't know which, overloaded
  8. I notice that RNB now has a lithium battery pack for the Vanquish priced around $60. I have been using RNB battery packs in my Etrac for years and probably will buy one of these Vanquish batteries, if there are no bugs needing to be worked out. I intend to keep the Vanquish in my car trunk and will only use it sporadically. Regular rechargeables don't seem to hold a charge if they are not used for a long time. In contrast, the RNB batteries seem to hold a charge indefinitely. I want to be confident that the detector is going to work even if it has been sitting unused in the car trunk
  9. Hey All, Measured White's TDI SL factory battery packs and discovered the following differences. NiMh Battery - HD #802-5321, 2200 mAh. After full a charge, one day later..........................................10.99 VDC AA Battery Holder - #802-7150, 8 cell. With Nuon Industrial Alkaline from White's Factory............12.94 VDC With Member's Mark Alkaline from Sam's Club...................12.96 VDC With Energizer Ultimate Lithium...........................................14.46 VDC Was very surprised that with Alkaline batteries, the t
  10. Buy yourself a metal detecting flashlight holder $5, and a power bank with built in flashlight $5-$20. I personally prefer the larger waterproof solar power bank with dual LEDs. Great for night time surf hunts All available on eBay.
  11. It took me 4 short hunts to finally run the battery down. Total run time was approximately 11 hours and 35 minutes. That sure beat the 3 1/2 from the factory battery. I ran about 95% of the time in AM and only switched to Tone or Mute to check targets. Running mostly presets on the other settings. The audio of certain targets is starting to become inbedded in my brain now. Nickels are easy to recognize now.
  12. Got my BBB (Beachnut Big Battery) 11 hour (est) run time battery today. Hope to give it a spin tomorrow. This should help me from having to backpack extra gear around for 3 1/2 hours or until the first battery quits me. I opted for the standard headphone connector to keep things simpler. The standard FT hearphones seem to sufficient at this point. Although I have been reading a lot on some of the threads about adapting other headphone for the AQ. That may be something I need to address down the road but not for now. I am just now starting to discern one target from another and don't
  13. This Battery musical chairs .....was a big thorn in my side ..... This Pack is all black and well balanced it looks like the rest of the machine was built to compliment the battery pack ....I chose the M12 connector from my old 3030 headphones gray ghost when they made good stuff my daughter bought me a set for my simplex last Christmas never worked I called left a message never called back new In box .....still dead ....guess they went out of business...anyway .... you can shift this a little up or down to balance it out a little more on coil control.. Good Job Big Joe.....
  14. Just a short note on Joe’s “shorty” AQ battery. It fits well under the cuff and balance was not noticeably effected from the lighter than stock battery. Run time for me in “tone mode” was 6 hours 20 minutes. It is my understanding that in all metal it is approximately one hour less. The M12 (CTX) phones connector was a welcomed change and the power cable with a small loop and ninety degree connector also worked well. Get one of his battery set ups and avoid changing batteries in mid hunt, while they are available. I believe he has other set ups with even longer run times. Knocked it out of the
  15. I even bought the universal charger with 4 USB ports from Minelab and NEVER used anything but this to charge the machine. I have used it three times, I plugged it in the first night and I though it charged it fine. I had not been paying attention and today the fourth time I took it out it flashed BF. Left charging all day and green light even stays on indicating that it is fully charged but when I turn it on its flashing the battery meaning its less than 5% charged. very frustrating, going to try another charger that has greater than 2 amps. Thanks for any comments / feedb
  16. Being a Fisher Repair center for the South East Back In Los Banos era I met and talked with some very incredible people from Jim L. President of Fisher Research Labs To a few legendary Relic hunters of that time in the south east that needed help Repairs inspiration or a pointer in the right direction...... To this day I still have my Repair manuals and updates some the best electronics ever conceived Mike asked me not to sell or give out the technology .....I have always kept my word. I would have 3D printer or a jig and router and a one inch extension of the battery lid on
  17. After a busy week, doing an effort between heavy rain interruptions, I finally finished this work! Thanks for all people involved in this project for their knowledge shared... Underwater test next week(I hope)
  18. Click or double click any photos in this article for high resolution versions. I bought this 4 x 26650 battery holder on eBay after quite a bit of Google work. They are a surprisingly rare item. It comes with sleeves that can use 4 x 18650 batteries also. It ran me $29.65 delivered including shipping and tax. I ordered it on June 25th and it arrived from China on July 14th. The holder delivers 16.8V via a DC adapter plug or 5V via a USB outlet. It has a thin oring on the lid for an IP67 seal. I also ordered an IP67 M8 4 pole 16.4 foot female to pigtail cable from Automation Direct fo
  19. I hope this topic hasn't already been covered and I'm not writing it in the wrong place. Recently, based on my lack of knowledge in this sector, I have however noticed large differences in actual life, not only because of battery chemistry ... I mean something about the use of power itself in using the tool. Thinking of a mobile phone, the standby time is merely relative to the battery capacity, as is the duration in call or video call, much less long ... So every time a detector is used in an area where there are several signals and we are busy digging or at least hearing many of them
  20. Joe, are you using a bms module inside the 4s1p tube?I hope not because.... I actually don't know if I'm correct but seems to be the easier combination for a self balanced recharge without the need of multiple solder and little cables around cells, not to mention the module itself presence inside the pod... I'm developing a similar pack for the Tdi and can be the base for the future of my dreamed AQ...
  21. Hi! after a year of snorkeling with TDI BH I concluded that I can clearly note the sensitivity goes down ones the voltage of my battery pack goes down. Other conclusion was that even at 12.6V the TDI BH is noisy underwater at maximum settings: it reacts to the waves. Thus at the moment I really prefer to have just a stabilized battery pack. For my experiment I took a couple of 21700 5aH Li-Ion cells and a dc-dc booster board. the plan is to get "one hunt" battery pack.
  22. Does anybody know if its possible to use a solar cell panel to run a small electric bilge pump for a small highbanker? Will it have to be in direct sunlight ? Mine is a Johnson 2200 gph bilge pump that pulls 8 amps at 12 volts What size panel will I need and what do they cost? Can I run the output straight to the water pump or do I need a controller thing? Or can I use a panel to recharge my 12 volt ,15 amp gel cell and how long will it take? Thanks. -Tom V.
  23. I just finished the next iteration of my 9V to AAA battery adapter for my Pro-Pointer AT (Carrot). You can read about it in my blog post that will be uploaded soon (see my profile for the link, if you're that curious), but most of the "juice" is in the pictures. In case you're wondering (or you don't recall my prior blog posts about this building process😞 1. Yes, waterproof integrity is maintained.2. Yes, the performance when using this adapter is identical to using a regular 9V battery.3. Yes, this can still use a regular 9V battery.4. Yes, runtime is less than with a regular 9V bat
  24. I've successfully removed 9V batteries from my Garrett Carrot (which now uses AAA batteries) and I've started on the process and getting rid of 9V batteries in my Fisher F2. I've taken the approach if trying to use a single battery to power the F2. A while back, I read from somewhere that the F2 ran off two 9v batteries running in parallel. However, this means that if I use a single battery for the F2, it should work (assuming the single battery has the ability to provide the necessary current). But when I try to use this set up, my battery gets warm. I eventually realized that the Fishe
