When you press this button after turning on the detector, does this ground balance the unit. Must you keep the coil still when its going through all the beeps?? Have no book to refer to at the time I was out with my friend. But we turned the machine on, I hit Noise Cancel and waited for the machine to quiet down, and proceeded to detect. Found a couple of metal washers. Must you hit the button that says Detect?? I suppose to take him out this Friday and just needed to know the turn on and go procedure to get him rolling along. he likes to sweep very slow. is the explore a slow sweep speed??, I was moving the coil like I did with my XLT which has a pretty fast sweep. of course we are always told to slow down, but I take that slow down as moving forward and over lapping your sweeps. I will be hunting with my XLT. The DFX is in the shop and it would not ground balance in some of the Whites pre-sets. I called them and they said send it in. At least I will know the machine is working correctly. Just give me the quick turn on and go, no need for anything else on the explorer right now, Thank You.............Pete
