Useless information probably.
I have two WM-10's (actually 3 but one is not working-battery) and Friday the unit I was using went dead. Battery charge exhausted. I got the backup unit and turned it on and it was also dead. So as I have an F75 as a backup detector and it has the Garrett Z-Link on it so I can use ear buds without a cable attaching me to the unit, I decided to try the Z-Link on the CTX. Very surprised to discover it is excellent on the CTX, maybe better than the WM-10. The Z-link is smaller, lighter, easier to adjust volume, etc., and about half the price.
As I said, probably just useless info, unless you have a bad WM-10, battery or whatever, and discover the cost to get it repaired or a new battery is more than the cost of a Z-Link.
