Just a suggestion , but you might want to try some of the people who post their treasure hunting vids on You tube on a regular basis. You can get a pretty good feel for the type of character they are. Off the top of my head I would suggest you contact Nugget Noggin. Younger guy who posts great T hunting videos both in the water and on dry land. He seems very charismatic and is quite knowledgeable on the hobby. Look him up , you wont be sorry. I bet he'll be able to suggest some others for you to contact as well. Good Luck.
