I use a Propointer and am very happy with it in all respects. I have never used the Harbor Frieght item, but, I know that piece of crap freebie, the Automax V4 (free when you buy a detector, about $50 if you buy it outright from Kellyco), isn't worth having. Yeah, it works, but, you better have that silver dollar touching the end of it to make it sound off!.....plus, it is big and clunky. Although it may be better than nothing, it ain't a Propointer! I gave mine away.
Whoa! I just took a peek at the Kellyco site to make sure I got the name right and the Automax V4 is now $140!! I guess the new belt clip is really expensive!! Also, they are no longer "given away" with a detector purchase, they just knock the price down to $59.95!!
Edit: Crap......I already said all this once! My only excuse is alzhiemer's.
