I've had my tiger Shark for three years now, overall I like it and would buy it again. It is difficult to ground balance in the black streaked wet salt sand of east coast beaches, but it is usable there. It runs a little better on the white sand beaches of the Caribbean and Mexico. I start out in normal mode, and only use salt mode if it won't ground balance in normal. The salt mode does seem to reduce it's performance some, but it is incredibly stable in normal mode and can often be used this way in wet salt sand. I run the discrimination between 1 and 3, it depends on conditions, you'll have to play with that setting yourself. I have never adjusted the sensitivity from the factory setting. It is an awesome machine in fresh water, where I use it the most. It does hit on small stuff and gold chains that PI and multi frequency machines will pass over. The only thing I would change if I had to buy it over again is I would have gone with the 10 inch coil rather than the 8 inch.
