My wants include
a light weight detector but with a lower leg strong enough to help old knees up off the ground.
a MD that comes out of the truck ready to go [ auto balancing, self-adjusting, etc...]
a MD that will reach down a couple feet.
a MD that can accurately tell what is in the hole, sort alum from gold, etc...
and a coil that can expand or contract to meet my needs that day.
