an Outlaw too..?
Congratulations! You two are going to have a great time!
Read up on that Outlaw and how the red button works. I use the button mostly in parks to detune/pinpoint in disc. mode. Remember to retune after using it though... Do that by holding your coil up off the ground a couple feet, then either hold the red button in again OR flip your toggle switch over to "auto" and back to disc. Either of those will retune (reset) your threshold sound and sensitivity.
You can pinpoint fine just by "X-ing" the target, but also using the detune function will get you right on center.
BTW - I like to set threshold so I can barely hear it. Doing that gives me the best info on depth; small, deep targets give softer signals and shallow targets are louder.
Run sensitivity as high as you can, and ground balance slightly negative. If sensitivity is too high though, and ground balance also set too positive, larger coins like quarters will sound weak. You need to find that just right balance for best depth and relatively quiet operation in disc. mode.
