Nah, you guys just didn't practice long enough. You're just being a bunch-of kill-joys. Tsk tsk. I mean, shucks, do you find a gold coin every time you go out md'ing ? Of course not. So why the double standard when evaluating this product ? Huh ? Huh ?
They do indeed work. You merely take them out, wave them at enough likely looking ruins, pull our your detector to "pinpoint". Dig countless holes, and .... when you FINALLY dig up a goodie, then presto !! It worked !! (hard to argue with success, eh ?). And if you DON'T find a goodie, it DOESN'T mean that the device doesn't work. That only means either 1) You need more practice, or 2) durned those sun-spots anyhow !
