I have noticed that my Excalibur II with 10 inch coil can occasionally produce false signals where there is wave action present in salt water. These false signals are typically quick chirps and/or changes to threshold. When I reduce sensitivity it does help out but even at the lowest sensitivity level (and when using auto) the false signals are sometimes still noticeable. While the machine is still usable under these conditions it is a hassle as I sometimes feel the need to recheck a signal to determine if it is a false signal or not. This behavior is also most prevalent when in deeper water i.e. a few feet or more.
I have tried with and without a coil cover as well as securing my coil wire with Velcro in a few spots. On some beaches, particular in Tampa Bay or in areas protected from wave action my Excalibur is very stable at 12:00 sensitivity going from dry sand, to wet sand, to low water, to waist/chest high water. However once I am at a beach where wave action is noticeable, such as Clearwater Beach, then I start to get false signals. Sometimes it is only occasional and other times it is more persistent. The rate of false signals seems to change even on the same beach perhaps due to variations in wave intensity
Is this sort of falsing normal behavior for the Excal 2 with 10 inch coil? And if so I wonder if it would be lessened if I were to use the Excalibur II with the smaller coil?
