First, thanks for answering some questions, and great video once again!
OK, just tested my Pro Pointer with a ruler on a clad dime. Keep in mind it's been used and abused and dropped, although it seems to work like the day it was new. The battery isn't new like yours and probably has about two months of use on it. Don't know if these things have voltage regulators to make that a non-issue. Also keep in mind this was in my backyard, and I have a power line running right over head. A clad dime also isn't as conductive as a silver one, so all these above things could shorten the numbers for the Pro Pointer perhaps a bit. I did the test in the grass, as cement can have rebar under it and alter things.
I powered up and did both tests right after, so no drift of higher sensitivity could take place as others elsewhere have noted with both these pinpoints I believe. Some say they get more sensitive the longer they are on due to drift. Normal hunting conditions means using right after powering up, so that's how I did the test.
Normal operation- 1 & 1/4" on the clad dime. That's 1/4" deeper than your test of your Pro Pointer that showed 1".
You said the Minelab got 1 & 1/2" for your first test which you didn't say but I think was 4 clicks up from lowest gathering by how many beeps down you went later on (4)? I think you did beep it four times when you lowered it, and then the longer beep tells you you can't go any further down but still doesn't equal another setting drop? That means the Minelab is only 1/4" deeper at it's 4th highest setting.
Your highest setting, which I believe was 5 clicks up based on the beeps I heard (?) was a just A TAD over 1 & 1/2", so the Garrett was only roughly a tad over 1/4" less in depth than your highest setting. That 1/4" difference could easily be due to me testing near EMI, or the fact I'm using a clad dime instead of a silver one, or that my Garrett has been through the wringer while the Minelab is brand new maybe?
Supertuned- 3". Wow! That's more than I thought I'd get. Judging from your video the Minelab also got 3" about in depth super tuned, so it appears super tuned they are equal. That's probably the clincher for me, because I don't want to mess with various sensitivity buttons. If I need extra depth I just super tune and it appears it matches the Minelab supertuned. Keep in mind I was using a clad dime too while you were using a large token, so the Pro Pointer probably would have gave me more than that 3" even.
Also keep in mind for both these pin pointers that these are air tests and not with an actual coin in the ground. Besides having the potential for a halo, the very ground load could push the pinpointer more towards the edge of sounding off, so I suspect at least for normal unsupertuned operation the depth of both pinpointers might be a bit more.
One more reminder, my battery being a few months old (that should only make a difference is the Pro Pointer doesn't use a voltage regulator), my clad dime (versus silver), my proximity to EMI producing lines right over head, and the fact that I still used the clad dime for the super tuning versus that large token could have all altered these tests for me, not to mention my Pro Pointer has had a rough life while the Minelab is brand new.
At this point, the lack of more depth of the Minelab super tuned (and probably less depth if I had used a large token as my target too), combined with what I've heard of it's weaker audio and vibration (from some), I think I'll stick with the Pro Pointer until I see more that says otherwise, which very well may happen.
I'm a Minelab guy so I'm not knocking the thing. I just haven't seen anything yet that shows me more depth here when super tuned, and the slight 1/4" increase at the 4th and 5th setting non-supertuned isn't going to make me take the leap yet. Detuning is as easy on the Pro Pointer as super tuning so I'm not worried about being able to do that with a button too much.
I await more Pro Pointer/Minelab video comparisons, as many variables can alter results. Your video was an EXCELLENT head start on that regardless, so I thank you again for doing it.

Once again, thanks for taking the time to make the video and also to answer some questions. I'm sure many will like what they see for various extras such as being able to turn off the audio and take the jump for that reason alone maybe.
We need others to test the Pro Pointer with a silver dime for comparisons to mine, as well as using a large token as the target when super tuned to judge more either way here on the Pro Pointer's exacting performance under more similar conditions, but I think it held it's own nicely even with some possible handicaps in my tests.
