There really isn’t Jim, it’s an addiction. We have ALL questioned our own sanity at one point or another regarding how far we might drive, how many hours we might spend, how tired we might be and still go detecting...but in the end it’s a quest to SEE IF WE CAN DO IT....the thrill of the hunt. We’re not ”making money” at this. In some cases it has taken away from family time, or put other projects on the back burner....but it’s OK. An addiction with an actual positive return is one I can get on board with! Thanks!
