Put it this way. Hunted for years without a pin pointer, then used a few others like the Whites and Centech and all of them were more hassle adjusting then just digging the coin without one. Then a friend shows up one day with the Pro Pointer that his wife got him as a gift. When I heard she paid north of $100 for it I thought "yea, she got took...no pin pointer is worth that much..." Needless to say after I "borrowed" it here and there that day it wasn't soon after that I bought one myself. Just over $100 and worth EVERY penny! Now I'm so spoiled that if I had to give up my Pro Pointer I would give up metal detecting. I mean that. A few times the battery died and I didn't have a spare 9V in the truck. I just left rather than hunt without it. Gone are the days of fussing with the sensitivity setting on other pin pointers and still not getting them to not false, and even when tuned just right they just didn't get any worthwhile depth. Gone are the days of having to get back up to use the machine to re-pinpoint the target. Gone are the days of waving the plug in my hand over the top of the coil. Gone are the days of giving up on a coin because it's under a bunch of roots and you can't figure out exactly where to poke your digger to pop it out of there.
Check this forum for a recent thread with videos and comparisons in depths of the Pro Pointer to the new Minelab. My Pro Pointer is only a tad shallower in air tests when the Minelab is turned all the way up, and when I super tuned my Pro Pointer (easy to do) it matched the 3" in depth the Minelab got super tuned. And, I was using a clad dime as my target while he was using a big token about the size of a large cent as his target. For that reason I bet my Pro Pointer might have got even more than the matched 3" in depth because a bigger target will sound off at further distances. I might test that today with a large cent and post the results in that thread.
The Minelab has some extra features that some might want to opt for. The ability to turn off the audio and still have it vibrate is attractive to some, but some Pro Pointer guys just tape foam or something over the speaker or use their thumb to cover it if they don't want it sounding off near people or something. Being able to lower the sensitivity on the Minelab is a big plus to some, but I can also detune my Pro Pointer by putting the tip near metal when it's turned on too. Useful for isolating multiple metal targets in one hole, or to trace out the shape of something to see what it might be.
The biggest issue for me is stability when it comes to pin pointers. The Pro Pointer auto tunes at power up so it's way less hassle than all my prior pinpointers were. On a rare occasion it will false due to the ground, but that's an easy fix by turning it on with the tip touching the ground.
If you want the extra features and a tad more depth without supertuning then get the Minelab. But if you don't need the extra features and possible will get even more depth than the Minelab (remains to be seen...going to test that) when supertuned then get the Pro Pointer. Both are excellent units from the looks of it. Way better than anything else on the market, but we'll have to see if the Minelab keeps it's performance over time with use and abuse as well as if it suffers from any reliability issues.
