VLF-Several...BHID300, DP Wader, ( have a used CZ20 coming) in the wet sand and suds
Wet sand - CZ6a , DFX
PI - Goldquest SS V2 PI. Smoothest PI I have ever used in the wet sand and suds. Not waterproof though, although I am trying to work on at least getting a waterproof case to house the entire unit it. Once you have the GQ set up, you don't have to mess with settings. Threshold hardly ever varies and only when a wave goes over the coil, but it re-stablizes in 2 seconds. The reject and SAT adjustments along with the 2 filter switch make this machine easy to set up for any wet salt sand and suds hunting. Also, once you learn the machine, you can tell most shallow iron and nails. And its set up to hit hard on lower conductive targets like nickles and gold jewelry.
