Polar Plot Does Not Lie on the V3i

[Neil in West Jersey]

I made a video that I think will be very helpful to V3i users who are trying to understand the usefulness of the Polar Plot feature.

The video shows a target I came across with a steady VDI in the high 70's, with tall thin bars on the Spectragraph. It also showed the dominant frequency as 2.5 KHZ in Pinpoint Mode. Check out the video as Polar Plot is put to the test! (FYI, I was using Best Data)

As I've stated I don't use polar plot. In my type of hunting were I am hunting for deep silver the plot loses the clean lines on the deep ones. This is in my soil. How about doing a video on a deep target. It would be interesting.

I can see it's use on the shallow ones.

As I have said before. On deep targets the lines are never straight, but if the points fall anywhere on the right side near the horizon it is almost always a non ferrous target regardless of what the VDI or sound.

Interesting Neil, I know you have done allot of experimenting and researching with the Polar Plot. This is good to know as I have always looked for straight lines but never considered the points of the lines in the non-ferrous quadrant. This may be another method besides the ones already mentioned in the forum of determining if i'm looking at a nail 9" under the ground. Gonna have to try this. I sorta gave up on the Polar Plot on deep targets but it is nice to know if the deep target is ferrous or non-ferrous.

Thanks !!

I will try to capture it on video on my next outing. Thanks for the feedback.

I own a VX3 which doesn't even have polar plot,but interesting enough the VX3 owners manual has a good explanation of whats going on with this.
