Treasure hunting is fun and extremely exciting. Probably the easiest place, in reach without really getting serious, is the Florida Keys. However, it gets complicated and some time down right scary if you get on someone's claim or don't have the right permits. I was not even pitching the underwater detectors, the land ones. For instance, I made 3 dives in Hawaii while teaching a local shop how to use underwater communications. All were fairly deep dives so now I am dirty and can't dive until the next day. What do I do, walk the beaches of Honolulu checking out the great scenery (if you get my drift) while stroll along detecting. Within a short period of time, I found a gold and platinum wedding ring! It had Japanese writing inside. I also found a pocket full of change, 1 ear ring, a Sako dive watch and two small silver rings. Its also good exercise.
I have used my detector in Taiwan, Bangkok, Coco Island, Singapore, Japan, Florida, Alaska, Virginia - well just about everywhere I go! I have to warn you though, you will get a lot of heckling from teenage boys. For some reason they love to make fun of you? That is, until they lose their car or house keys. Then they become your best friend!
