Bought my Excal in January, and for the last 6 weeks have been giving it a go, mostly at Hampton Beach in NH. Threshold-small whine, volume pretty loud cause I'm pretty deaf, disc-1, sens-auto-most of the time, have had conflicting advice on auto/man sens at highest livable level. Been digging pull tabs at a much deeper depth than I was with the Fisher 1280x, been finding lots of clad coins, foil, pull tabs, bottle caps, juice pouches, parts of lobster traps, plastic Easter eggs-the candy inside was wrapped in foil, and various aluminum stakes for the canopies people bring to the beach. Last Sunday, went at sunrise, I love being on the beach then ( hate getting up that early to do so), and beat the heat. Found an earring (wife says it's a belly button ring, whadda I know),925 silver, with an amethyst stone. Today, bunch of pennies, and quarters , and a 10K gold ring, and a 925 silver men's wedding band . Finally found something I'm not embarrassed to post here. ( I mean who wants to look at crusted up zincolns?). Artie
