I have one of these. When I bought My new detector from Kellyco, for a small price extra this was included.
I like it and it works well,but I have no experience with any other type, so I can't give an unbiased review.
Good luck & HH
80 bux is what they go for. i have two and both work well. my only complaints are that it is too big and is a little fragile. i still wouldnt consider hunting without mine though and for the money i think it is an ok deal.
