I don't like hunting tot lots. When I do I get in and out as fast as I can. To do that requires the use of a CleanSweep Coil! I have considered wiring one onto a Compadre to take advantage of the ED180, but some of the older uMax's use it too. Another reason the Compadre is so good on gold is the smaller coil. You could put one on any uMax. Too slow for me. Can get closer to metal bars and such with DD CSC anyway. Still might try a Compadre out one day but really don't feel the need.
