I am buying a Metal Detector in the next week or so to use on the beaches here in MB. I do not have a lot of money to spend but am looking at Bounty Hunter TK4 Tracker IV. I am mostly doing this to get out of the house and get some exercise. But I would love to have some excitement too. What do you think of the Bounty Hunter? I only have around $100 to spend. Thanks in advance for any tips or suggestions.
