Manticore M11 V M15 Sensitivity

[Tony]

I picked up the M15 coil a few days ago and revisited the same beach that I hit with the M11 coil a few days earlier.

Is it just me (I don't think so)....but I was able to set the Sensitivity quite a bit higher on the M15 than on the M11.

I recall the M11 was set on 21-22 but the M15 was happy on 24-25.....wet but not saturated beach sand.

I'll test again but it appears that the M15 can be set about 3 points higher in the damp sand.

It's not that way with my M15, I've actually had to stay at the same sensitivity level and even bumped it down a notch some days. I'm hunting very salt saturated beached though.

That's what I would have expected as well but so far, the M15 (same setting for setting) can accept a slightly higher Sensitivity setting.....I'm sure the environment was the same (similar tide times and area of beach).

I'm wondering if it's related to the GB settings that I may have had (or not had). I recall the M15 hitting higher GB values when doing the GB procedure.

you read  my mind, Tony.  I was  just going to put up a post asking if anyone had had the 15 in to salt.  NOX was pretty crappy overall just not handling the fast surf and  contours.  To be  fair, 5 tone spreatd the  signal  out a bit and made it less chattery.  Keep  us posted...

Hello Clive,

I've only used it in ankle deep water for a short period of time so any observations are somewhat limited.

For me personally.....and in my conditions, I "feel" the 15" in the water. These "open web" coils have a lot of leading edges that the water really grabs onto. In deeper and/or calm water then it may not be too much of a problem. I'm finding that lower sensitivity settings isn't diminishing the reach of the Manticore on deeper targets. I'm still trying to find the sweet spot with the Sensitivity settings.....I don't mind running a detector a bit ragged but I feel the Manticore doesn't offer a lot more "depth" at the higher settings....more so in the saturated sand. I've used pulse detectors for a long time and so running the Manticore in the "Prospecting" and "Deep Beach" is just an extension of the pulse detector. I don't want to make the same mistake I did with the "10uS Pulse delay at all costs" mistake I did many years ago.....too much salt noise and not enough gold in fast salt conditions !

How ratty do I run the Manticore.......no point in running at 25 when 20 does the job just as well (and getting better target ID)

Love this machine....seriously impressed. Got some homework to do in regard to the Sensitivity setting on the Manticore......so easy using the Sens on the Excalibur (let it false slightly and then back off a touch).

Maybe I need to read your book !!

I ran higher sensitivity usually 23 - 25 because of micro gold jewelry.. on my beach the lowest sensitivity I tested  was 21 for ring/coin size targets.. Running higher sensitivity gives better chance for the manticore to 'capture' the fine jewelry/whisper faintish targets on discovery swing.. IMO..

My problem is I like chasing big gold.....big and heavy gold is down deep and I don't want to drown out these fringe targets with too much salt signal audio in the background.

Hi Tony

It is odd to see a larger coil that can hold higher sensitivity. I have had larger coil options on many different detectors over the years.

My question is: have you fringe depth tested compared to the 11" coil?  

I would be concerned this coil may not be working correctly.  If you are for sure getting the same depths or better...........Don't ever sell that coil!!!

With the modern machines, Equinox, D2, Manticore.....I have been setting my sensitivity where I know that fringe target will respond, and I can hunt comfortably without a lot of falsing.

Then if I need a better look at just that one target, I up my sensitivity, two points or more if I can.

I have 6 hours of beach time with the 15" coil. It was mostly dry sand/towel line and all I can say is it is deep. Deeper than any other non PI machine I have used. I think I have figured out whether or not something truly is iron and worthy of digging but if you are going to use the 15 on a beach you must dig everything. I dug a quarter in the dry sand that had a non-ferrous tone but red numbers in the 40's and 50's. It was down at least 18" in that the dry sand was no longer dry but wet. The key to dig was the tone and by no means was it good or clear, rather it was just not iron. You cannot go by any of the basic signs like you would if digging in the dirt, you have to dig everything. 

The 15" is the real deal. I have a job tomorrow to try and find a couple of gold bracelets. I took my wife's gold bracelets out and compared my 800 with the Coiltek 10x5 and the Manticore with the 15 to see which machine I would use to find them. The 15 identified each different bracelet/chain by tone and TID, the nox and the 10x5 never even saw them.

The manticore represents a new day in detecting capabilities. It's a game changer.

In my testing the Manticore is a chain killer. 😎
