I haven't used the Garrett, but guys seem to like it. I have my original VP and would not be without it.
In my opinion, a "pinpointer" should pinpoint, not just detect several inches into the soil, on all sides.
My VP only detects on the tip, and only about an inch away, so I can "pinpoint" my target easily.
If you need a pinpointer that has so much "reach", maybe your detecting technique could stand some improvement. As far as going detecting without a pinpointer and passing handfulls of dirt over the coil, I think that wastes alot of time. (not to mention the mess it makes unless you keep all the dirt crumbs on a towel or ground cloth)
I dig a horseshoe flap, fold back and put dirt on cloth. Pinpoint, and refill.......
Just my humble opinion, and it works well for me!
