  1. Bunch Of Nokta Impact Coin Digs Filmed

    Nicely done video, I really enjoyed watching his live digs. Got a kick out of his excitement over finding the half too. He may claim to be a relative beginner but you can tell by the amount of targets he dug learning the machine that he has the right attitude. Good job! Tom
  2. Steve The Fisher 1270 was like that. The volume control also controlled the gain. With the volume set high you could still get coin sized targets at good depths with the sensitivity set as low as 1. Also if the machine got a bit cranky at high sensitivity lowering the volume smoothed it right out. It wasn't just me that observed this behavior Keith S. also commented on it. Tom
  3. Part of my beef with the 705 was the faint target response on 10"+ coins. They were there but oh so faint. Whether or not that was due to running the threshold at 7 or not I do not know. Now with he Mars 10x13" Tiger coil in place of the 10.5" DD ML coil and the new set up, targets in that range are clearly heard. Could be mostly attributable to the larger than stock coil or a combination of both. The end result is I'm happy with it as a deep coin hunter..
  4. Hi Steve In disc with a wide open screen I set the threshold at 0 anyway for silent search. Using a stock or modified coin mode is were this helps being able to hear the blanking of the threshold. Re the Impact, I am not sold on it however, as it turns out I am getting the chance to test one here in a week or two. Word is the audio is at least somewhat better than the blendy/bleedy R2. It doesn't matter to me how well it performs if I can't adjust to its language. Tom Oh and by the way, the proper way to set the volume is to start low and increase it to a comfortable level. Try it, you will find it not set as loud vs the way you were doing it.
  5. Very nice finds. Any idea how old the gold ring is? Tom
  6. 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.
  7. TNSS I simply meant dominated as in the choice of many (but not me) for deep coin hunting with good TID. Sorry I didn't make that more plainly stated. Would have saved you the long post.
  8. $3000.00+ for a machine that will beat the better single freq machines by an inch or two on a dime? I would not pay it! The cost benefit ratio just doesn't add up in my ole noggin. If you want to dominate the market with such a machine, IMO you have to take the opposite approach that ML has, $2400.00 for the CTX has always been a huge joke to me. I don't hunt salt water beaches or trashy city parks, I just want a machine that punches deeper in my mild to medium ground. It would not have to be waterproof to 3 meters either since I use single freq machines for fresh water hunting. Current multi freq tech has dominated the market for a lot of years. The return on investment to develop the tech must be huge for the manufacturers. I do not know how detector makers calculate ROI, is it 5 yrs or 7yrs, to break even? Or would looking long term to dominate the market with a price tag that beats ML style pricing be better? FTP, I'm looking at you. All this talk of be willing to pay 3 grand is silly! I would not pay a penny over $1500.00 for a better next generation coin machine. The ole Jackpine
  9. Storms Are Good

    Sweet ring. Going to brave it tomorrow at a local beach where the ice is out. Tom
  10. The New Tesoro Mojave

    IMO 630 Hz audio freq is just plain dumb. Us old guys need 750 Hz minimum. Listened to the audio on one of the vids and would not like it at all. Tom
  11. My First Ring From Last Year

    Nice chunk of gold!
  12. I have to go with Steve on this. While a nice top end machine that is capable of many types of hunting, it really isn't doing anything much different from what is already out there. I feel I have it covered with what I currently have and enjoy using all of them too. Tom
  13. Somebody Should Make A Jewelry Detector

    Going along with the lower frequency idea I got out the "new" Id Edge and put the 6" coil on it for some testing. First thing I noticed was the thing was responding to my hand at several inches????? So, I taped my (pt) .1 gram test nugget on a ruler and the dang thing hit it with low positive numbers and clear audio out to 1 1/2". Had to recheck the manual... 6.25Khz. crazy. Now that I think about it, the smallest gold chain I have found fresh waster wading was with the ID Edge. One thing about this detector, it has a narrow field which helps in iron but you really have to use a lot of overlap. Also, having used a lot of so fast response iron hunters I can say that the ID Edge gives the most accurate target ID I have ever seen on severly co-located coins in nails and not just your typical nails, large rusty spike sized nails.

  14. Why Dig Zinc Pennies?

    Funny thing about how alloys effect the conductivity. In actuality when alloyed together two high conductors read lower. Take the ring I posted, although it has good mass, the fact that it is 20K or 83% pure gold helped push it up into the zinc range. I have found many large 14K mens bands and none of them read much higher than tabs. Tom
  15. Somebody Should Make A Jewelry Detector

    Mike I agree on the lower frequencies being better discriminators. Detectors such as the Fisher 1270 with an expanded disc range in the right area and a volume control that acts more like a threshold control can eliminate small foil bits easily by the audio response. No screen needed. Tom
