I have two Discovery 3300's. After I bought my first, I got rid of allot of expensive MDs that won't do what it will. It's light weight, good discrimination, you can hunt right up against chain link or most metals, hunt old homeplaces in all metal or go to the park and discriminate out anything less than a quarter if you want, great pinpoint, runs forever on batteries. I haven't owned the SS II but if I remember corectly, the 3300 has an extra feature or two. I think that's what made my decision between the two. And I think the 3300 costs less. Check them out, apples to apples, $ to $. The SS II has a better written warranty but don't let that worry you. I'm never concerned about a BH warranty. BH will take care of you. Great people to deal with. I doubt you'll ever have a problem with the 3300, I haven't. If you get one you can buy your second one with the money you sell your Sovereign for. Digum
