Multi Salt is a dedicated simultaneous multi-frequency mode that rebalances the VX7's algorithm for conductive saltwater environments. Saltwater is highly conductive, and naive multi-frequency engines treat wet sand and surf like a giant non-ferrous target, causing false signals and unstable threshold. Multi Salt adjusts the frequency weighting so the threshold stays smooth and the two-tier Target ID keeps calling coins and rings cleanly right up to the waterline. This is the single biggest reason serious beach hunters step up from the VX5, which does not include Multi Salt.
