Thank you for your response. I have been interested in detecting for MANY years. To illustrate this point, my first detector, of which I still have and it works fine, was a Pioneer Bounty Hunter EX. I dabbled over the years in the hobby, then, I purchased a Teknetics Delta 4000 a couple of years ago and still dabbled, but more consistently. However, lately, I have been consumed with the hobby, watching videos, then I started looking around my area as I travel daily. I have a large river with an old fort, a large lake with camp grounds, about 1.5 hours from one of the most beautiful beaches on the gulf of Mexico, as well as a town within 20 miles that has a hughe historic district, with restored homes, from 1823. Not to mention the old schools. I am dive qualified, if this goes well, I thought about eventually getting a detector that is water proof to about 15 o 20 feet, to detect some of the natural springs we have around here that are used for canoeing.
