I also have a Sea Hunter Mark 2 and I believe that it is more of knowing the beach, combined with a little luck. I bought the sea hunter because I didnt know if I would really get into the water hunting, however I love the water. As far as the sea hunter goes, If I was making a decision today it would not be my detector of choice. After taking the 3 hour trip to the beach today to give my new explorer a test run, I would go with a minelab excalibur. I will probably sell the sea hunter and do that in the near future. Anyway, after seeing the performance of the Explorer 2 twice on spots I hammered and also at the beach, minelab knows how to do it. Plus they seem to hold their value fairly decently. Look at the resale of a garrett and look at the resale of any minelab unit, there is a big difference on resale value. I was simply amazed with the explorer in the wet sand plucking coins out from 14-18". I not trying to sell minelab and I am fairly new to this hobby, so if you want a newby thoughts, there you go!!
