Looking for a beach machine? Here are a list of PI/VLF and Waterproof and Non Waterproof machines. This is not every machine out there that works on the beach but its a very comprehensive list. Also, please note, any machine will work on the dry sand in a salt beach so I am not including those. These are machines that will work on the wetsand and/or water. Also, these are machines in production. Older models are not included. And for those that do not know VLF is a machine that can tell the difference between iron and non iron and PI means dig everything. If you are not sure if you need a PI or VLF that means you more than likely need a VLF. PIs are not really beginner machines in most cases.
VLF Waterproof (multifrequency):
Whites BHID 300
VLF Non Waterproof (multifrequency):
Tesaro Sand Shark
White's Dual Field
White's TDI (Non waterproof)
Garrett Sea Hunter
If a machine is not listed here its probably not going to work on the salt beaches wetsand/water. If you are unsure please ask because new models are always coming out.
