So I did finally find a review/air test of the pulsedive on youtube, 8" coil. While there was an increase in depth it was disappointingly small considering coil diameter. It was only somewhat better than a super tuned minelab (or other pinpointer I suppose) though I suppose you could potentially super tune the pulsedive as it is a non motion detector and has a somewhat expandable threshold much like a typical pinpointer. I paid about $170 for my pro find 40, I'd pay as much again for the pulsedive to get perhaps a couple more inches on a good day with no other obvious benefit, at least the minelab can fit on my utility belt along with trowel, spade, brush and every other tool I lug around. Likewise I'd still require the minelab to pinpoint the target precisely as the 8" coil is not quite as good at that bit. Hmm, I don't think it's an improvement, it'll add weight without enough benefit to make it worth it. The pro find 40 it shall remain until further notice is given or until one of these companies hears my prayers. I guess I shouldn't search after more, I actually do pretty good with that pinpointer finds wise, in fact, all of my very most impressive MD finds were made with that little magic wand. I enjoy hunting with it but no, you're not gonna find me crawling about with it, bent over perhaps or down on one knee to dig and do further spot searching around a given feature. It's a style of hunting unique to itself is what it is.
