Pro Pointer
Well, I just received one, but we're still iced up here in the frozen North (MN) so I won't get any field use in until spring.
I have three other pinpointers, all from detector pro. They are the Uniprobe, the pistol probe and the uniprobe with headphones. This last one has been outstanding, as are all the Detector Pro products.
But...I ordered the propointer for a different reason. Its true the detector pro gets the most depth of any pinpointer I've ever seen. That's good in most situations. However, if the pinpointer will detect a coin 4" to 5" inches deeper in the hole, you've basically not gained much, in a way, as your detector already told you how deep it is. Knowing the coin is 4" deeper is good, but that's really not pinpointing any better than what your main detector told you. So I wanted another one that had a bit less depth (yes LESS!) as there are times when all I want, is to find the target in loose soil I've already dug. Also, the Garrett signal (both audio and vibrator) increases in intensity the closer you are to the target. My air tests get about 3" on a silver dollar. and approaching 2" on a silver dime. Its hard to explain, really, but the Garret's size and overall design looked to be very rugged (it is, too!) and the features were such that I thought it could fill a niche.
Another reason is, I love detecting so much that I can't avoid buying accessories that I think might come in handy. If its well made and durable, goes 'beep' close to metal, and is reasonably portable, I usually save up and get one!
