Just learned about this pin pointer and I'm intrigued...but then again any new pin pointer from a major metal detecting company catches my attention.
Based on the few videos I've seen and the Minelab website, here's my too-early conclusion about the Pro Find 40:
Compared to the Pro Find 35, this will be an improvement in terms of detection depth capability. At the very least, I imagine it will have the same sensitivity as the Pro Find 35, but will enjoy less intereference or glitching. It will also have better ratcheting or closing range, compared to the 35, too.
Compared to the XP Mi-5/6 and the Fisher F-Pulse (old version, at least), it won't be a significant improvement, but might have some nuances that make it preferable to some users from a personal-use stand point.
Finally, I'm surprised it's still using a 9V battery. My reading between the lines says this MIGHT be an indication that Minelab is either cutting corners out of laziness or simply didn't prioritize this pin pointer's development and that the Pro Find 40 is really a red version of the Pro Find 35.
All I know is that I'll stick with my F-Pulse for now. Maybe if I win a Pro Find 40 in a raffle or something I can do a direct comparision using my hunting styles and locations (like I did with the Garret Carrot and White's TRX...both of which handily lost out to my F-Pulse).
