Recently purchased a new (12/16) t2 classic. Got the nel sharpshooter coil. Like what I see so for. Looking at getting a good coin machine and the e trac and ctx interest me but I am concerned that they will struggle (with depth) in my ground. Fe 3-4 bars (some 5 bars) and G.C. phase is 65-75 and some areas up to 85. Anybody using/used these machines in ground like this? Do they fare well or should I look elsewhere?
