Hi everyone! I'm new to this forum and I find it very useful. I'm relatively new to detecting as well. Started last summer with an Ace 250 and now with a Tesoro Lobo, I've been thinking about upgrading to a GT as I've heard that's a great all-around machine and that's just what I need. I might to for an Excalibur to make it even more versatile, not sure yet 
My question would be, do these machines have multiple sounds in AM or just a single?
If I go for the Excalibur and look after it, will it still be waterproof after let's say 3 years of use? I would mainly use it on land and occasionally in salt and fresh waters.
Thanks!
