I just used it in freshwater for my first time and it was awsome! I hunted in both all metal fast with background threshold and in disc mode with the disc set real low at about 3. It sounds off sweet on targets. Loves bottlecaps, but so do most detectors. The coil is nice and thin and slices through the water with ease. Ground balancing was simple and it was the first time I ever had to do it. For the price I don't know what more you could ask for. I found a ring, several clad coins and a bunch of bottle caps the first time. I wouldn't trade this detector for anything. My thinking was if you are going to buy a detector for underwater detecting get one with a lifetime warranty. That left the Tiger Shark. When I researched it I never found anyone that had anything negative to say about it. Now I see why. I also want to hip mount this and try it on land. I see Tesoro makes a hip mount pouch that works for this and the Lobo. You will not be disappointed with this detector. I also have the 10.5 inch coil. Make sure you get a good sand scoop! Check out the T-Rex, it is light weight, stainless, and strong.
