Minelab Geo Sense Pi

ML have filed a lot of patents the last few years regarding "improved metal detectors" or something to that effect. I wonder if this logo might not be a full detector but some kind of technology with it's own logo. Like MPS, SETA, etc etc.

For instance, something like this patent which seems to determine the position of the target in the ground related to the position of the coil using some coordinate system, and then plots it on the screen. This patent here is similar, except seems to use similar ideas to improve the performance of auto ground balancing, and specifically references PI machines so maybe the new "thing" has to do with it? I just read the abstract but it almost sounds like it uses GPS coords to "remember" the ground balance it learned at that spot, and uses the same information to re-ground balance to the same settings when you go back to the same spot? I dunno, I need to read the full patent some day, that seems pretty innaccurate since GPS is only accurate to like 9ft on a good day.

Or maybe I was thinking about this patent. Similar idea, with some diagrams of the guy moving his coil around.

Of other note, there are some patents related to enhanced signal processing (potentially discrim, or better ways to deal with variable ground) and dealing with salt. Also newer patents on constant current machines (the GPZ is one of these). It sure seems like a new prospecting machine should be on the horizon, but it just never seems to arrive...

Anyways, cool to have some mystery to look forward to again at the least.

My brain says it is signal imaging.

My offline moving map gps phone app with all mapping, mineral occurrences, google earth and tenements is my most valuable prospecting tool. Rather not have a big screen dangling off my machine. (Wish machine had small robust screen)
