Beach Mode For Park Cherry Picking With Far More Accurate Id's On The Manticore

For example, we've been told in the 800 manual that Beach 2 gain/sensitivity has been scaled back from Beach 1.

Lot's of good analysis in your post regarding the comparison of the VDI scales and sensitivity ranges, but just wanted to clarify that ML states that transmit power is reduced not gain/sensitivity in Beach 2 or when the Nox goes into Beach black sand overload mode.  So I'm not sure mode plays into the sensitivity variation equation when comparing Nox and Manticore.  FWIW.

I found the lower the sensitivity goes the more stable my ID's get.  Less is more it seems when it comes to the Manticore, 

I have been exclusively salt beach hunting in and out of the water and use beach low conductors and surf modes. While wet sand hunting yesterday I was running beach low conductors around a sensitivity of 23. A little on the edge of over sensitivity for my conditions. I’m always thinking about small chains being so difficult to find in salt conditions I tend to run as high as I can. I got a fairly good sounding target but the ID was jumping around and the audio wasn’t a good solid sound. For the heck of it, I lowered the sensitivity to 20 and everything calmed right down with the ID solidly locking on a good number and the audio was solid and consistent. It turned out to be a dime about 10 inches deep. So I do agree that when I checked a questionable target by using a lower sensitivity it was spot on. I am using the prospecting audio as I found it seems to hit targets deeper and it has a sharper audio response. Lots to learn and experiment with. So far I’m pleased and it has gone 25 hours totally submerged with no problems.

Also, the Sensitivity control on many detectors effects the receiver Gain AND audio Threshold levels.

3) I'm throwing water on the argument some people are claiming:  tying the the gain scales together on the two detectors.  25 on the Eqx 800 is 25 on the Manticore?  Where'd you get that?  25 on the Eqx is 35 on the Manticore?  Where'd you get that?  Since when is what you expect a substitute for the truth? 

From page 1 of NASA Tom's Manticore thread he states:

"Yes..... Sens now goes up to '35'. And yes..... a EQX Sens of '21'..... is fairly equiv to a Sens of '21' on MC."

Good to know!  Thanks for clearing that up.  "Fairly close" is still open to interpretation, but if he had said 'exactly' I would have been skeptical.  ?  Apparently ML made an effort to align the two scales, within the constraints of changes in hardware and software.

Addendum: Here by 'align' I mean what Tom D. is quoted above -- similar numerical values correspond to *approximately* the same gain.

I don't know about the scaling, but I do know that my nox 800 with sensitivity of 25, recovery speed of 4 IDing targets as iron, which manticore with sensitivity of 28, recovery speed of 4 ID the same target as nonferrous (jumpy ID). Now manticores at my country gets a bad rep among other detectorist due to bigger and deeper holes and they jokingly said that the manticore is no longer allowed to enter the sites ?

I've been playing with the Manticore quite a bit, I can't do much digging unfortunately as we are in a drought and the grass is a bit dry and brown, if I start digging up the fields I'll be causing damage which I don't want to do as I want to maintain my access to these areas without causing trouble so I've just been finding targets with the Vanquish or Equinox 800 and comparing results.  The Vanquish is and has always been my best cherry picker out of the multi-IQ machines, its jewellery mode and EMI handling is just great around here, perhaps its the v12 elliptical coil helping I don't know but it is always the most accurate with ID's on these deep coin targets, and that's still showing now.  I wish the Nox had the Vanquish coils.

The Manticore is actually doing better with EMI than the Equinox, mainly because I can run the Manticore in lower sensitivity settings and still get the depth, where the Nox starts to drop off the Target in lower sensitivity the Manticore is still doing great at 14 sensitivity, these are coin targets at 20-30cm deep (8 to 12 inches), I have dug a couple of targets just to be sure what I was finding but I'm purposefully not digging much at all unless in a spot I'm not concerned about the ground like in the dirt car parking areas.

The 2D Target trace is working very well, ID stability although not quite Vanquish is doing pretty good on lower sensitivity settings, if I try go over 16 to 18 the stability of ID's drops away, this is in All Terrain General, in Beach mode I can have 25 sensitivity and still maintain stable ID's on the same targets.

The fields I'm detecting are in a town that does have quite a bit of EMI even underground powerlines under the field,  outside of the town area I may not see this Target ID instability in the higher sensitivities, I'll find out with time when I try it in more places, it's just hard at the moment as I can't really dig anywhere where I'd find good stuff with the dry ground so it's not worth going anywhere further away.  I may have to wait until a change of seasons before I can go and see if the Manticore will find me anymore silvers in my fields I've missed with the Vanquish/Nox and then CTX.  It's certainly showing promising depth, it is deeper than the Equinox and Vanquish, that I'm sure of.  I'm not so sure it's deeper than the CTX though, I can't lift the Manticore coil off the ground and still get good hits on deep targets like I can the CTX so in long grass the CTX is likely to be the better choice for me.

Plenty to learn with the Manticore, I'm much happier with it now I know to keep my sensitivity lower and I won't be missing these deeper targets by doing so, it really has improved the Target ID a lot by doing that.  So far so good, really like the Manticore.

The more I read. The more I think the scales are NOT aligned. My thoughts are the Manticore is ahead on performance number for number with the Equinox.

I'm confident they're not aligned.
