Alittle More Research
ANiceMonkey
I have a Bouny Hunter Sharp Shooter II, Bounty Hunter 505, I am happy with my machine. I paid $250 about 2 years ago, purchased from amazon.com. If I had it to do over again I probably would have bought a Garrett Ace 250 or spent alittle more for a dectector that was alittle more versatile than the BH. The Ace 250, I believe is going for $212 on amazon.com presently. I don't like buying used. I am not sure how much your friend is asking for his machine? If the machine is in good shape and is below the $300 mark then it may be worth buying. IMHO you may want to do alittle research before buying a used detector. You may be able to find a mid range detector that approaches the price of the used detector that you are considering buying.
