mention that they were going to broaden the GB swing to include salt? Most Single Freqs you have to change a button/setting to enter salt mode. So does this new machine swing far enough "natively" to cover salt? Which is what you seem to be indicating.
If you have a chance next time you're near the beach, would you take a small piece of gold, set to FP, air test for distance, then GB against the salt, and re-air test for distance? It would be interesting to see if there is any sensitivity loss once the GB has swung that far. Because what you are describing is pretty wild!
If you have a chance to do that thanks, if not, I understand, you're a busy guy.
