Traded the Cobra Chinese unit in on a Sea Hunter Mark II as most of you know. I have had it out twice on practice runs and just waiting to find the time to get it out for some "serious " work or about as serious as I can get! 
Took it to the park and did some static tests first. Found a lot of junk but this is a small park that I personally have hunted it out pretty much. I am use to a machine with a big LCD screen and lots of bells and whistles. The Sea Hunter is a PI based machine with very little discrimination and it loves iron based metals as well as treasures! It reminds me of hunting in all metal mode with my other detectors. Was able to figure out what the tones were telling me to some extent. Although there is only one tone, the strength of the signal can give you some idea of the size and depth of the target. I am sure I will get better at it with use. It will pick up the smallest metalic target and I got strong hits on a couple of bobby pins!
Went to a local freshwater beach and did some runs on wet and dry sand and worked some knee deep water for about 30 minutes or so. Not seriously hunting, mainly just testing. It picked up targets equally as well in wet or dry sand and a little black sand did not interfere with it in any way. Worked equally as well under water as on the beach. Got a new scoop from Zeke and recovered all but one of the targets I hit in the water. Didn't find any jewelry or coins which is what I was hoping for, rather recovered a dozen or so large nails and one RR spike and some more of those melted globs of aluminum cans. The lake was up and I was essentially detecting the same area I had been over with my GTI 2500 when the beach was exposed. Was able to discriminate out pull tabs to where they just gave a faint whisper of a tone while a gold ring I tested rang out loud and clear. Gold and silver both ring out just like iron based metals so you never know what your target is. Like most PI technology it is a true dig everything detector. I had no problem pinpointing, just place the coil where it made the loudest signal and it was dead center every tiime. I had a little trouble locating underwater items with the scoop. The scoop worked fine, cudos to Zeke, but I couldn't see the coil due to muddy water conditions and it was hard to dig in just the right spot. I more or less had to slowly scoot the scoop along the bottom until I contacted the coil and then try to dig in under it. I was afraid I would damage my coil so I had to go really easy with the scoop. I would suggest a coil cover at the very minimum when using it in surf or muddy water. I don't know how you surf guys do it with the constant surf and sometimes rough water! I didn't go in more than about knee deep because I was alone and the old Cimarron River channel is notorious for drop offs and quick sand. The beach was not in very good condition due to constant rising and falling water. It was littered with much debris and a good portion of it was under water as the lake level was up. I explained on an earlier post that Lake Keystone is a flood control lake and the water leve fluctuates a great deal. This factor also made it evident that the beach I went to was not being used as heavily as in past years. There are better beaches to explore but this one is isolated and no problem with swimmers or sunbathers, just a good place to do some testing. There are some excellent sandy beaches and several old home places up there on the lake that can only be reached by boat but I sold my boat last year! Guess I'll have to hook up with someone local who has a boat? Hope this give you some idea as to what to expect from any PI water hunting detector. They all work basically the same. JIM
