I'm sure Monte can answer this for me. I used the Conquistador to hunt a lakes waters edge a while back. I did find 3 rings and the machine did good, but at 2 freshwater beaches, the machine had a couple of false signal spells. I figured it was electronic field interruptions. Went back today with the Silver umax to both beaches, and had no falsing. I did get the coil wet on the Conquistador before it went a little crazy. Is the spoked Conquistador coil waterproof? The coil cover is still on it. Maybe that needs to come off for a cleaning? Thanks for any help.
