So the other day I got around to re-testing my Pro Pointer with a large copper token that looked to be the size of the one he used for his target when he super tuned. I kept turning off/on and re-supertuning the Pro Pointer to verify results and I was getting 5 & 1/2" some times, 4 & 1/2" others, but most of the time after turning off/on I was getting right about 5". So it appears the Pro Pointer might beat the Minelab when both are supertuned, because using a clad dime the other day I still matched his 3" supertuned depth. I know these depths are probably going to be much different in the ground and don't expect to get that much depth in normal use, but it's good to know the Pro Pointer appears to have the raw power/sensivity to at least match the Minelab when both are supertuned.
Now, here's one thing about it...I did all my prior testing and then this test by laying the Pro Pointer flat on it's side in the grass, so that it was being soaked in a ground load. Because you can super tune these pin pointers and do air tests and get great depth maybe, but when they are touched to the ground they'll sound off even if no target is present. You have to back off the air adjusted super tuning a bit once the tip touches the ground in order to make it not false on you. That's why I did my test with the Pro Pointer on the ground, so that I wasn't getting better testing in the air that is unrealistic because it's useless when it touches the ground. See what I mean? Also, the testing has to be done right after power up, because both will get more sensitive over time due to the capacitors heating up and causing the auto tuning to drift.
Anyway, so I'm pretty happy with the results. Looks like the brand new Minelab was only a little deeper at it's max setting, and my Pro Pointer has been through the wringer in terms of abuse and dropping on hard cement about three times by accident. I wonder how the Minelab will do say a year from now after it's been beat up as well as how realiable it's going to be. I'm also curious about it's battery life as I get close to a year out of my Pro Pointer's. Somebodoy should read the amp draw on the Minelab with the speaker and vibration both turned on to match the Garrett, and take measurements with the unit not sounding off to a target as well as under load (audio and vibration going off). If the same is done with the Pro Pointer we'd then be able to see which one has higher amp draws at idle and sound off, and then that's the one that won't get as good of battery life.
