Gold and polar plot

[Low-Boy/LCPM]

Anyone able to tell the difference or have a better clue on gold verses trash. Any tricks that may help? I was able to tell crown caps from clad because of the different Freq that hits on those targets. How do I program the V3I for polar plot? And what do I give up when I do that does it add it to the other readings or do I lose something in order to use it?

I am one of the few V3i users who find the Polar Plot feature useful. First of all, it is set by going into the Expert Menu>>Configuration>>Analysis>>Polar Plot>>ON., Then simply push the toggle forward and sweep the coil over the target.

On gold targets you should see the blue or red lines being the dominant frequency. Solid rings should show as straight lines, but other jewelry may show as curved or even squiggly lines, so I would not think it would be very helpful for gold ID.

I like Polar Plot because it helps me determine whether the target is a coin or a button, usually in the red or green range, but it has been helpful on some gold as well. As with any ID, whether an old meter or a VDI number, gold is very tricky. My only advice is to dig it all and deal with the trash.

When using the Polar Plot feature, you give up the sizing feature of the V3i. Personally, I think the audio is a better indication of target size. Small targets have a tight pinpoint sound, while larger targets, including twist off aluminum, have a somewhat more spread out pinpoint.

Thanks for the info I will try it and see how I like it. So you use it for relic hunting?

Yessir!

There is no way to tell gold from any other metal that has the same VDI. The day a detector can perform this trick it will be the only detector sold. Over the last couple years we have had many screen shots for the Polar plot and analysis screen. They all tried to see a pattern for gold and all failed.

Experiment and see what works best for you. I don't use either screen but that is my personal choice which is not better than other peoples. Rob

Neil, you are not alone oh wise one! I too find polar plot useful. Coming from a GTI 2500 as my former detector which features sizing you would think I would value sizing over the polar plot, but that has not been my experience. The polar plot has really helped with sprinkler heads out in the dry country where I like to detect. But as another good V3i vet once said; "when it comes to the V3i there are many options and different bites for different likes." I find they all taste pretty good too!

I hunt only for lost jewelry with my V3I, beach / sports fields, what I have experienced with polar plot is that it gives you a indication on ferrous or non ferrous targets and that's all I got from Polar plot.

You still have to go by the solid VDI number for Jewelry, over the 4th July weekend, I was dry sand hunting at my local beach, and got a solid 11 VDI reading

( I was thinking it was the 110th foil target of the day) and when I kicked the sand over the target, to my surprise a gold ankle bracelet with a gold charm go's air born

I made the mistake and showed it to my wife, and have not seen it since?

Dig all your (foil) VDI's at the beach


Good luck HH

Absolutely! In order of importance I go with tone-VDI-frequency-analysis (polar plot, etc.) and it works very well because I do not dig all that much trash. For the exception of some very odd bottle caps and a single type of pull tab that ring in a good VDI's and give all excellent indications. Yet they fool me no where near as often with the V3i as they have with other machines.

Digging the foil targets is great advice on the beach. Not to mention it clears you beach for you! Ok, that was a joke but it is great advice.
