Hey guys, I went to purchase a garrett at pro at kelleymetaldetector.com and the sale says I can also purchase a cobra beach magnet for $180, a viper hybrid trident for $170, a 1st texas titan 9000 pro for $150, and a bounty hunter pioneer 505 pro for $110 on a second purchase. Are these metal detectors any good? Seems like low prices. Does anybody use these? Or are they just trying to get rid of not so good metal detectors? Opinions please. I am new to this, so not sure. Thanks, Gohndd
