Just ordered the Ultimate 13 inch coil for the V3i

I am still new to the Whites V3i, but I have heard good reports on this coil so I have one on the way. Is there anything special I have to do to the machine after I hook it up? Any pointers would be welcome.

great coil. you'll love it. mine stays on about 3/4 of the time. the 6x10 and 5.3 get the rest. I can hit a 9" dime loud and clear in my test bed with it. None of my other detectors with any coil will do it. I just set my coil setting to the 300 12". at that setting I'm within 1/2" on coins. some say to use the d2 coil setting but I found it was a couple of inches off.

Thank you for the reply John. I am waiting on the v3i to come back from whites ( Tune up ), and during that time I am getting things ready to go. I also ordered a 6x10 coil for it.

I've had the U13 for my V3i about 2 years and it is an excellent choice for coverage and depth. I think you will find the weight and balance very favorable. I have the U13 for three different brands of detectors but have the most time with it on my V.
Good luck.

My U13 didn't come off for 2 years them I got the Detech 12x15

The 13" ultimate is an awesome coil. It's very stable, especially for a larger coil. It's hits a 12" quarter with accurate vdi numbers.
It also has amazing separation. I use it 75% of the time. You'll love it and good luck !

I'm new to metal detecting but I've been vigorously using my V3i every day for over a month with the stock coil. Even with my noob skills, I noticed a huge difference in the U13 the very first day I put it on. It seems like I can cover more area and I get better discrimination on coins. I may try other coils at a later date but for now, between stock and U13, the U13 will be my daily driver. Great coil for a great detector.

Happy Hunting!

Hi John,
I enlarged the words above to bring attention to them. I am getting a V3i tomorrow. I have a 13" Ultimate that will work on it.
What do you mean by" setting to the 300 12"?

How does one do that?
Also, do I need to let the detector know every time I change a coil?

He's referring to loop selection of Super 12 (300 mm = 11.81 inches) in the advanced settings. This will give the most accurate depth readings during pinpoint + OR - a 1/2" with the U13 mounted.

Does one need to do this every time one changes a coil? So if I put on my 13 SEF, I make changes in loop selection but then I put on a 7" coil, I need to make changes again?

The coil settings don't have any effect on performance.your depth readings will just be a little off. You will need to play with your recovery delay. Raise it to a little higher number with a larger coil. I usually run between 80 and 90 with the 13" I usually run it about 45 to 60 with the 6x10 and 30 to 45 with the 4x6. Thats what i found works best for me. The numbers will be a little different depending on what filter you are running and you sweep speed. I made a test bed in my yard about 3 years ago and it lets me play around and find the what works for me in my soil.
