Hi everyone, I have begun to hunt more frequently with my 5x10 HF DD coil on my 705. ---- I have discovered that by using 4 tones, and the All Metal mode, this coil keeps getting better and better. -- The soil is fairly mild in most places I hunt, (primarily coins and jewelry), and though I own 3 other ML coils, the 5x10 is my favorite. --- I had not tried using the 4 tones before, thinking that 3 tones was all my brain could handle. --- To my surprise, 4 tones is easier and better. -- It gives the higher conductor coins, (both silver and clad) a much more distinctive tone. ---- On my hunt yesterday, I was able to identify my targets (for the most part) without looking at the VDI display. --- I would take a guess at the number before looking at the display, and was usually within a digit or 2 of the readout. --- If you haven't used the 4 tone option, I highly recommend it. And the all metal mode will get you 1-2" more depth. Just thought I would pass it on. Thanks
