I found .33 cents, no jewelry, and no trash ??? with mine in a week of detecting in Destin last year. I was NOT impressed with it in salt water. It is an AWESOME machine in fresh water, but my experience with it in salt wasn't impressive at all. I had the sensitivity adjusted to just a hair below falsing in the water ( it would still false when a wave flowed over the coil so I don't think I "dumbed" it down too much ), a low threshold, volume full up, salt mode, and hunted both in AM Fast and Discriminate - set no higher than 2, with the 8" AND 10" coils... Yes, I ground balanced it! Nothing I did would make it perform in the salt. At the end of the trip I did an "underwater air test" and found it wouldn't hit on a quarter 4" off of the coil, or a dime at 3", re-adjusting the sensitivity didn't help, it just made it false constantly. It WILL regularly hit on a single stud earring in fresh water, but seems to be blind in the salt. I am heading back to Destin the 23rd of this month, with my new Excal II... I will hopefully enjoy my vacation in the water this year using a proven salt machine, without all the frustration of trying to use a machine that is out of its element. I still have the Tiger Shark, because it WILL find very small gold that doesn't even register in air tests on the Excal II, but for me it is a fresh water machine only. Kudos to those who can make them work in salt water, I have seen the posts, and know there are a <very> few of them out there, but mine wasn't up to it. By the way, I had NO problems with it up in the dry sand, found plenty of junk up there!! HH Joe
