We've got two of these along with a White's Surf PI. Good machines. First machine I've used. You'll find a lot (of stuff). Plan on digging.
We got done looking through a 7 acre lake. Took us 1.5 weeks. Two of the Sea Hunters going non-stop 9 hours each day. What they were
looking for wasn't there. I guarantee it. However we did find about 100 soda cans, lead sinkers, fish hooks, 5 porta-potties, 1 cool OBX license
plate (now on the front of my truck), a remote control sailboat that didn't survive the waters, an Ugly stick and Penn reel, roofing tiles with aluminum
backing. Visibility was 2 feet at the surface and zero at 18 feet. bottom was from hard sand near shore to "muck", 4 plus feet of it, after the first
thirty feet out. I found cans at an arms length into the muck. Strong signals. Pinpointing with the coil.
Oh yeah, don't forget to take your wedding band and dive watch off, that always seems to get me for the first 10 minutes.
