All metal sounding off on every swing ????

[jbow]

Sorry I forgot about this thread. Thanks Brad for reminding me!

I will be checking everything out but I am pretty sure that it was the Garretts pinpointer because I never had this problem with the original F75. I didn't have that pinpointer then... then again I hardly ever hunted in AM mode with it.

I wont be able to get out and test it until sometime next week but I WILL be letting you know what happens. I had already learned to leave my cellphone in my truck when I use the F75, the cell doesn't seem to effect some detectors like it does the T2/F75. It never even crossed my mind that my trash pouch or hand digger might cause a problem... I try to keep my shovel back out of the way but i'll be checking that too. Maybe a shovel quiver would work well. Obviously all pinpointers aren't a problem, else the SunRay inline probe would be a big problem.

and I suspect you just got the answer to the left swing report in AM thing. On the other issue, certain ground matrix conditions will keep a VLF from hearing a minnie at half the 11" you're trying. It can even be a strain for a top of the line ground balancing pulse. The reason I asked in your other post about checking GB values off the target and over it is to check and verify the amount of difference between the two. Your BBS is detecting it (using it's auto trak) but as iron at least initially and that "initially" is what we go by more often than not unless we are investigating every target in detail. When I hunt over around Culpeper, I have to do that as most of the targets have a partial or total "ferrous" ID signature but there are PLENTY of signs to figure otherwise if that is the case. I just want to see if the single freq VLF's that don't autotrak can "see" the target at all and the two GB values will give you an indication of that. IF the two values are in fact different, you should at least have a shot hearing something when the LTD is in AM switched from BP or CL from the disc side of the menu along with whatever sensitivity/threshold setting gives you a rock steady threshold.

Maybe that was my prob the other day. First time I wore the probe on belt.. Clarify please..so I can make certain your saying what I think you said. Thanks appreciate it.

over the bullet the GB is 2 digits higher. When I BG a foot away then move to the target I can clearly hear the negative response then the balancing... then it ends up 2 digits from the TID of the minnie. I am going to try tomorrow setting the GB on the White's V3 really high in single freq 22.5 and in 7.5 and see if that does anything.

Thank you!

I think what they are saying is that the Garrett pro pinpointer coil is tuned close to the same as the F75 coil and it interferes a lot when the probe is off... don't ask me to explain, I cannot but i'm pretty sure that is the deal. When it is on it does not interfere as much if at all. I guess it is just when one is one and one is off that they have a problem. I'm just glad to know about it and glad that the Uniprobe doesn't do it too!

I am just having a problem with this. No transmission, no signal. (Current) How can it interfere when their is nothing operating.

I could see this if it were picking up the windings in the probe. Be just like any other metal target the detector goes over, or is near.

Does the probe retain some sort of stored current in the windings that still gives off a signal. ???. Does this fade after time off.?????????

Is the stored current why Cell phones interfere, Is it the Battery that gives off a signal in the probe ??? ..Is it the battery in the phones??.

If thats the issue. A shielding should stop that issue.

Capacitors, Or something.. So if the electrical wave( Eddy I think) is getting to the electronics of the machine.. There has to be a shielding issue.
This could be a relative small fix. If the probes are off, then there is no frequency being transmitted...........if the electrical is still active (stored)..then it's just plain old electrical cross talk.Next question is....Coil, or workings in the detector..Which is picking up the current.?????????

because it makes no difference if the battery is installed or not. Also doesn't matter if the battery has been rermoved for days.

I agree Brad.
The test I did with my F75 and the pro pointer were conclusive. I didn't see any depth loss when the pro pointer was turned on or off and held in front of the control box on my F75, all the while sweeping the coil over my deepest buried dime. My F75 confidence is still optimal.

Have you checked this condition in several areas ??

Get some shielding foil and form it loosely aroung the Garrett pinpointer. Ease it down into the holster and remove the pinpointer. Then use something rounded, like a cigar tube or rounded off wooden dowel to press the shielding into the inside of the holster. Maybe do a double layer. If it works but tends to pull out with the pinpointer or come loose so that it may get torn... add a little adhesive between the shielding and the inside of the holster.

I bet that would solve the problem... for that matter I bet lining the inside of the finds pouch (I use the really great SunRay finds pouch) with some heavy shielding, that will hold up to abuse will fix the problem from the trash and the hand digger... or at least keep it to a minimum.

I can't think, offhand, how one might shield the relic shovel but I bet that at least the handle could be shielded. Maybe wrap some shielding around the handle, from the spade end all the way up to and including the handle. Then wrap that with some grip tape. The kind used for tennis rackets or baseball bats. My friend showed me some the other day he found somewhere that only sticks to itself... it is great for taping a foam handle, no danger of harming the foam if you ever remove it.

I'll try some of this but it may take me some time to get to it. Critterhunter may know a way to ground the shielding if it needs to be grounded... he seems good with this sort of thing.

Frankly, I don't have the expertise to directly explain this but DJ and Mr Bill both have told me their take is this is a situation where the two tuned coils (PP and the coils of the high freq Fisher/Tek) coincidently just happen to be at the resonance point of each other. Location has nothing to do with it...proximity of the two coils do.

I really don't think it is a big deal....just something to be aware of so that you wear the probe "appropriately". The biggest watchout is if you're hunting in AM and are trying to hunt the whispers and the probe (because of wearing it on your side instead of around back) affects your threshold potentially causing you to miss a really deep target.

 

[jbow]

I was hunting in an old park. I was running the disc side with the sens between 50 and 60 and the disc at either 20 or 6. When I use the AM side I was in motion; sens 60; threshold quiet; fastgrab GB.... if there are other settings that matter I don't remember then right now.

I had no problem whatsoever. I think maybe the problems arise when you are in clean, low mineral ground where you can run the sens high and the disc low. I tried using my Uniprobe but it stopped working again.
