It is a really fun little unit. It is easy to conceal to hunt places where detectors are not allowed. I use a full face snorkel mask which is fantastic to use while hunting. I can hunt 4 hrs plus without stopping. Have you been to my FB page, Goldsboro Treasure Hunting Lounge? Look through the photos to see what I have found with the Scuba Tector. At first, I did not think it would be fun finding newer coins, but I have become addicted. I have found a lot of jewelry as you can see in the pics, a couple gold rings, a few silver and even more ice rings. I slide a quarter up the shaft until the detector starts to beep, then back it off until beeping stops, and secure the quarter in place with rubber bands. That gives me an extra inch of depth. A little trick. Get on my FB page and let me know how you do when you get one. If you have any questions, please let me know. Also, Quest now sells a black one (vs the bright orange), which I would opt for for more stealth.
