After yesterday, I think my efforts would best be put to making an earbud set. The wind noise on the stock phones was pretty bad.

Get anywhere on this? Curious if it’s worth the trouble.

On sale because next version is much better - uses augmented reality and Apple’s VR headset.

Yeah I totally missed the fact that I was sweeping across the coil lengthwise!  But really I’m impressed as normally the depth will be the width of the coil - like 4-5”.  Actual depth typically can be better than air tests and will obviously be better for larger targets. So I’d say it is about perfect.  The majority of targets are in its range and hopefully it will miss some of the pop cans, foil, and tent stakes.

air test on gold ring (8.5”) and nickel (7.5”).

Here is another video of my Manticore at Newport Beach near Santa Ana River at an area with heavy black sand. I made an earlier video but didn’t specify what modes I tried. This one I do. However the default Iron settings are in effect - I didn’t try All Metal. 
Also interesting is this guy’s video that’s pretty close to where I was - he’s showing higher than normal radioactivity there!

Here’s a short video showing the ferrous content:

I saw one in a local mall but it wouldn’t accept my two iPhones from the beach that had water damage.  

Great news!

I had the coil wired bassackwards plus a shield was not being grounded.

I rewired it and man it runs perfectly in my front yard at least.  My front yard usually has a lot of EMI - but this detector is running dead quiet.  No jitter, no pulsating, nothing.  Not sensitive to shock at all. Can't tell its on unless you advance the threshold.  It was detecting who knows what in my front grass.  It remains to be seen how it does at the beach.  I won't be able to get out there for a couple weeks.

On my trifield meter the all terrain was a high output mode.  Maybe you have an issue with the detector or coil resulting in too low tx signal in the other modes. 

Got confirmation of n/c to loose pin.

The inner coax shield was left unconnected the way I did the adapter.  Maybe there is still hope for the Beach hog on the AQ…

As I’ve said on some other thread, it seems one of the AQ three coil connector pins is unconnected (it’s very loose). I know which is P and which is N. I can’t get my connector’s housing off to see without the likelihood of breaking the base connector. It just won’t undo.  I discovered that my Beach Hog has shield connections that I probably missed on my gpx to AQ adapter. 

Unfortunately it doesn’t work well. It has very good depth under the coil but is sensitive to changes in altitude over the sand. It sounds off with any abrupt coil movements. ATS and delay setting help quiet it down otherwise.  Just not practical due to the AQ design. It worked great on the Gp Extreme.  Next I’ll try it on a surf pi pro.

i took some more videos of black sand behavior of the Manticore as well as compared the AQ. Thought the AQ was going to work great until I walked with it.  Gold mode on the Manticore cut through the black sand pretty well.

i didn’t modify the AQ headset because I went back to my test site and this time could hear the whimper on the nickel at 16”. I had also been thinking of buying a Tony Eisenhower set but I think I’ll wait til I have an opportunity to try it first.  I don’t find a fault with the AQ headset and think I will likely move to a wired or wireless earbud system.

Finally decided on cable connector, got it quick from Mouser, and made an AQ to GPX adapter, and hope to try it in a couple days!  The shaft pins are 90 degrees off so it might move around and get annoying. I’d prefer it were longer too - the stock shafts are about 9” longer.  Any suggestions as to where to get the one I need?

What happened to the bad one?

Sorry I got you and Carolina mixed up. And he sent me a “12” case size number.

Yours looks great.

Joe, the shell size on yours is 14. On my 8” coil it’s a 10. Do they both have to be the same to mate?

Thanks, it might work (hope it does) but the one on my 8” coil measured 26x66, which is a UTGX6JC10E19P3, which seems not available anywhere. Yeah Carolina should know - he said he used them for other detectors too.

Also pin contacts are separate for UTS.  Next challenge.

The 30x7 is intriguing but too expensive for me to try. A $160 Arrow I would try. But I have a version of the 18x4 and will be trying it on surf pi pro and AQ.

You’re right.

If you are going to replace caps, test them after you remove them one at a time with a good meter that doesn’t just give you value but ESR and other parameters.  So many products have been damaged by people doing cap replacements without reason. The instructions for the XLT rechargeable pack say it is 10V not 12V. So either you are putting the cap in backwards or your pack voltage is too high. The CD4316 has a max VC spec of 10V so maybe you damaged several components with your “12V” pack.

So the one above is totally wrong.  Could be a UTGX6JC10E19P3, which no one stocks.  I’m sure I’m boring everyone with this stuff as probably less than ten people will try using gpx coils on their AQ… I measured the diameter and length of the plug on my 8” coil to match up to the above number. Easier to try the coil on my dual field first perhaps…

Maybe it is an artifact of running 5 tones? I haven’t tried changing to something else. Might be the highest tone in momentary bursts. Annoying for sure. Not repeatable over a physical area.

Indications are no pins included. Also there is a UTS and UTSX series and I’m not sure which is appropriate yet.

I don’t know why not much said about this type of coil with a pi. Actually should be ideal for the beach as it likely works better in black sand than a VLF.  As you say, just for recent drops.  This on a pi pro should be a fun, cheap, combo.  Detech makes several varieties of the arrow - wonder why not a pi one. So many detectors could use it.

Well I still haven’t gotten around to this and don’t know what if anything I ordered. So would this be the right connector (end of coil cable, going to the detector)?: 

UTSX1JC103S

Does it come with pins or do I need to order them?  (Not shown in Mouser’s photo)
