Ok, that is probably worded wrong. I have been detecting for quite awhile, but just started scuba diving again. With land detecting there is often the problem of finding locations to search because of ethical considerations and local, state and federal laws. Are there any problems like that when scuba diving? Is it ok to detect in just about any lake you dive in? I imagine National Parks, etc., are out of bounds. I have been searching the subject awhile and it appears that since there aren't a lot of questions about it that there must not be as many location problems? I just don't want to buy a $1500 detector and find out my ability to use it is severely limited.
