Pinpoint sensitivity adjustment

Is there a way to adjust the pinpoint sensitivity on the V series? From my basic understanding, I thought adjusting the AM would control this.

In pinpoint mode, I don't hear an audible sound until I'm practically on the target. The VCO is enabled. Once I'm inches from the target, I get a really quick increase in pitch until I'm past the target and then the sounds disappears as quickly as it came. Now if I slow my sweep speed to a snail's pace, the increased pitch can be heard better, but it's still fast.

Is there a way to slow this pitch down so I hear it longer before it gets to the target?
 
I don't remember an adjustment for what you want, but increase the All Metal sensitivity and see if that helps.
 
The AM doesn't do anything. Ironic isn't it - the machine is super adjustable but you can't decrease the sensitivity with the pin pointer....:stars:
 
Pinpoint is All Metal and All Metal Sensitivity DOES affect pinpointing.
 
I never heard your complaint. Raising the AM sensitivity will definitely pick up the target sooner and last longer. It also will make shallow targets harder to pinpoint especially when there are close targets.
 
Sounds like you may be pulling the trigger a bit too close to your target. Go into your menu and un-check "Ratchet" just below VCO. Try raising your search coil well above the target, pull and hold the trigger while lowering back toward your target. If you try to pinpoint too close to your target, auto tuning will reduce the size(area) and try to tune out your target. That is the reason for a quick blip in pinpoint.
Good luck and please keep us posted.

I have the VX3 so there's no ratchet adjustment. I've been detecting for 7 years and have never had this problem with White's machines. But as you said, yes it's like a quick blip unless I REALLY slow my swing speed down and then I can hear the rise in pitch with pinpointing. As an example, I will pull the trigger a solid two feet for the target and sweep across, about the same speed of actually detecting. As soon as I touch the target - BLIP. The sound doesn't come on gradual at the speed of my sweep. My sweep is at normal speed.

With my old MXT using a 950 coil, while holding the trigger and the coil is about 6 inches for the target, you can hear a low pitched growl. Gets louder until it finds its target. With the VX3, if I do the same thing, I hear nothing. Yes, VCO is enabled. When the edge of the coil is just about touching the target, then the low sound can be heard. You have to creep to use the pinpoint otherwise, you missed it cause all you hear is a quick bleep.
 
Just for the heck of it, turn the VCO off and try a pinpoint. If you hold the coil in the air,trigger pulled, do you hear a threshold? You should have one. If no, try to increase the thold. Also turn the SAT off and try it. Is the Vx3 new?

mxt has concentric(950) coil....doesn't vx3 have dd coil...if so....pp is different....just a guess??? hope ya figger it out.
 
I got the d2 coil for my vx3 and it was like i woke the machine up. I made some good finds with the 950 coil but the d2 coil is like night and day on my vx3 in my area.
 
I can't stand the 950 for my area. I bought another coil from a member but am waiting for it to come in the mail. I'm not too confident on international purchase though.

I hope a new coil makes a difference.
 
You had a 10x12 white SEF. If it won't handle your soil I don't know what will. Why did you sell it? The 950 is a great coil in all but the worst soil. Where are you located and what coil are you getting?

All my Whites coils and SEF pinpoint fine.

I do have a 10x12 SEF that I'm going to be trading. I want a 6x10, 6x8 SEF or a 4X6.

I need to make it clear that the pin pointer works fine, BUT, it just seems overly sensitive than my old MXT. I'm very competent with pin pointing. I just have trash everywhere I hunt.

I live in Phoenix, AZ. Severe mineralization. We call it "Caliche" out here. It's like cement in some places.

Phoenix has little history to dig anything that's worthy. Most of the historic places are skyscrapers now. Everything is covered by asphalt and cement. Unfortunate.

Occasionally, I've endured hunting in the old area of town where homes were built in the 20s and 30s. My oldest coin to date is a 1910 penny. That's pretty old for Phoenix.

The problem with hunting in the old part of town is that it's all run down ghettoville. Lots of gangs and very dangerous. IMHO, a detectorist has no business being there. You're asking for trouble. I had a very close run in with an attack last year. Maybe I'll post that story. Quick thinking got me out of it....

IMPO, you will want the 8x6 SEF. I just got one last week and it beats the socks off the 6x10 coil, at least my Eclipse which I got from day1 with my V3i 2 years ago. Depth is unbelievable on the SEF, and separation is wonderfull. If you really want PP, the 4x6 is the one. The 6x10 has always been a low achiever for me. martin
