Hi guys,

I am not having any problems with pinpointing.

The only thing I do not like is the tone.

Wish it was as sharp as the compadre tone..

Test your Mojave Pinpointing :shocked:

Just thinking today, in my post I said my Mo with the 7" pinpoints like a DD and not like the usual Concentric.
So I did a quick experiment with my dirt box 15 minutes ago.

Took a quarter, gold ring etc.
Turned down the disc into or below iron range.
Swept the coil across the target 5" below the coil.
I would get a positive signal from the coils edge to the coils rear edge.
Pinpoints just like a DD.

Now, run the disc higher slowly all the way until the target is disc'd out.
After each adjustment found the target response narrowed towards the target marked on the coil.

This would definitely explain issues I had with pinpointing.

Anyone else find this happening?

Just checked this air testing and in my test bed.
No difference with different disc settings.
Mine pinpoints great.
Is it possible that the coil on yours is wired backwards?
Inner transmit, outer receive?

No, something like that is obvious and would have been caught at the factory. The detector would not function at all.
Will wait to see if others respond.
By the way the 8x9 does the same thing.

That's puzzling.
Just front to back?
Not side o side?

Sven,

I got a chance after supper to replicate your finds....first test was on a clad quarter at 5" depth with a sen 4 and a disc 0... the Mojave hit hard on the quarter on the heel, center and toe of the 7" coil.
Next turned the disc so the quarter just disc out ..then turn disc back so I just got a hit in the center of the coil...began to move the heel of the coil ahead of the quarter and lost the signal...same results with the toe.
So with quarter almost disc out you only get the center of the coil picking up the target...
Got the same results with a gold ring as well....next changed out to the 9x8 concentric coil....finding were identical to the 7" precision coil.
Any idea why?

Whimp.

Don't know why but it is interesting. Kind of reminds me of the old Compass X100 detectors which had a switch to go from a wide beam (normal) sweep to a narrow beam (sharp) sweep.

It just may have some use.....................

It also tells me not to be to heavy on the disc....or your working with a 2" coil :)

Is this the only detector you guys are finding this with.
You used the other cencentric so it's not the coil.
I'm curious whether this happens with other detectors?
Does the ground switch play any part in this?
Very interesting finds guys. I have no idea what would cause this...

You have a bunch of Tesoros, try them. See what happens. I never paid any attention to this before, it just dawned on me-----Because of some observations made over the years:
Anytime I had a Tesoro that had all metal pinpoint, I used it. Faster than motion pinpoint. The Vista Gold I had was motion disc with a DD coil, no pinpoint button, which would have made it a perfect beep and dig. With a DD took way to long to pinpoint. Also, my PI search coil acts like a DD coil and a mono/ concentric coil when it comes to pinpointing.

The Mo ground switch has no effect on what happens.

I have been pretty much sick with the flu, so I can't get out and hunt with the Mo.............

I never noticed it but this merits further checking on my other units. Maybe it's something that happens on all models, or maybe just all 5 pins.
When I have time I'll test it out too.
Very interesting find I probably wouldn't have even noticed. Lol.
I only make it that high in disc when thumbing to help figure what's there before I dig.

Sven,

After testing my Golden µMax, Mojave, Silver µMax and Bandido II µMax....the results are the same...used different concentric coils all tested identical.
Definitely a loss in coil foot print at a higher discrimination...didn't test DD coils...only have the 3x18 clean sweep.
Not sure if it follows true with other make and models...but it's a sure thing with Tesoro's.

Whimp.

Well I'm happy with that.
I live the way mine perform and if the others do the same as the Mojave, it's no loss to me.
:-)

Thanks for the testing Sven!!!

Something new to me.

After 15 years of owning a Tesoro, never clued in on it.
Mainly I think, usually set disc just below foil 99% of the time and for faster pinpointing with a motion detectors switched over to slow motion or non motion all metal. Or I would hunt in all metal mode and just use the preset disc for target checking. With the Mo, since it is motion disc only detector, this is the first time I had tried thumbing the disc to help ID a target. Learn something new every day. So there is a very good chance there is nothing wrong with my Mo, just not using it properly.....and possibly GB is not set up spot on for the soils outside, it is somewhat mineralized with magnetic black sand, dirt and quartz sand. Will have to try the Mo in some different areas. All my Tesoros but one the Amigo had adjustable GB, so I never really encountered any ground issues. The Mo is what it is for the buck. It will find coins down to 6" so far and it loves Canadian clad without any problems. For that intended purpose it works just fine. But, still prefer a modified Silver Sabre Umax (just missed one) or a stock Eldorado.
