Any advise?

[999digger]

I recently set up a test garden for my GTP 1350. I burried a wheat penny at 6 inches and was surprised when I went over it. My detector did not a make a sound. Shouldn't the detector be able to sniff that out of the ground in a heartbeat? It did not make a sound for a silver quarter at 7 inches either. Is there something I am missing here. I want to get more depth. Does anybody have and advise. Should I look into a different brand? Which detector? Any advise would be greatly appreciated.

Sometimes a freshly buried coin will not register a new target until it gets the halo from the ground around it and settle up with moisture and all. I would suggest turning up the sensitivity also and see if that helps, good luck, Tim

Thanks for the advise. I already had the sensitivity on high though. What do you mean by halo? Thanks

The ground absorbs metals from the coin slowly over time. Like when you dig up a rusty nail and notice the soil around the nail is a rusty color. That is called a halo which is the soil in contact with the target and when moisture is present it kind of supercharges the halo and that is why you can find deeper targets after it rains and the conditions are good. hope this helps, Tim

Sorry, Garrett's aren't known for being depth demons usually especially on freshly buried coins. Since you already had sens turned up, there isn't much you can do except use a larger coil or change brands.

I disagree,... I have the AT PRO with the DD coil and I can EASILY bury coins to 8" and even 10" and although the signals are not the 'same' as a coin that has been in the ground for years, the signals are still very obvious. I just found a Buckshot Pellet at over 9" and an Lee-Enfield (known as the '303' here) shell casing at 12" and both gave me a very strong signal. Proper adjustment of the Ground Balance and Sensitivity is crucial.

Some years back I dug a 1917 wheatie at 11" and decided to test the test bed theory right then and there. I moved 25 feet or so from the spot and cut a plug, measured 8" deep from the surface to the bottom of the hole, then plopped a clad qaurter in and covered it.

With the same rig I had just used to find the wheatie at 11", I could not hear anything from the clad quarter. Same settings, GB, etc..

Swung around it for half an hour wondering if maybe I forgot to put the coin in the hole. Nope, pulled the plug, coin was there.

Sandman and LowBattery are correct, I have done the same test on Minelabs, Whites, Fisher and a Tesoro I have owned...... Airtests also are not the same as being in the ground either, some think if it airtest 10 inches it should hit on 10 inches in the ground, ground mineralization, position of target, ground balance as well as other factors figure into it......

Water that coin garden it will help.......

Yes, water the garden a and be sure to add some 10-10-10 fertilizer.
