Hi Andy, You need to get yourself a pinpointer!! They help you to locate the target in the ground. I personally recommend that you get a SunRay DX-1 Probe from Rick at R & L Detectors,he is G-R-E-A-T to deal with, and very dependable. He is also the monitor of this forum.
He has great prices on SunRay Products. They retail for $179+shipping, but you will have to get a price from Rick. Also, when purchasing from the dealers, IT IS EXTREMELY HELPFUL TO THEM, to pay with a MONEY ORDER. Credit card purchases REALLY CUT INTO THEIR PROFIT MARGIN!! The DX-1 SunRay Probe will get up to 3+inches on coin size targets in the ground. The handheld probes will cost you approx. $75-$100, will get you up to 1-in. to 1 1/2inches on coin size targets, depending on the make/model, and strength of your battery. I use to have a DX-1 Probe on my MXT, but I sold the MXT.
At present, I have (2) SunRay In-Line Probes on my Sov-GT, and my FISHER CZ-70PRO, and I would not dirt hunt without one. Also, Ronny Dugger at Dixie Metal Detectors in Brandon, Miss., also carries them, and he is also ONE OF THE BEST DEALERS TO DEAL WITH!!! Best of luck, whatever you decide, hh.
