Kellyco offers a bunch of cheap diggers, earphones and the like to sell more detectors..Really are a big outfit and bound to get compaints, shop around on the net for smaller outfits..They also offer good prices along with more of a one on one service. With Kellyco and their large amount of sales you are just a number. Many swear by them but I would shop around with their amount of sales they should beat everyone for price with the large numbers they buy and that is not the case...
