Has anybody used both the m8 and m9 to compare performance?

I am considering buying the m9 for some parks I hunt that have some moderate trash so trying to justify another $300 bucks. Doing the math on the area of each coil says the m9 is 63.62 in² and m8 34.56 in2 or 46% so it seems like it should get quite a bit more depth.

The m11 would and does also work great except just a bit big enough to create some masking issues so I started kicking around the m9 as my confidence in the depth of the m8 depth isn't that high although it runs pretty quiet most of the time.

I would not sell the m8 to get cash to work with as I think there are times when its sniping ability will be important, but don'know if I will gain enough depth to make the m9 worthwhile.

I woiuld be gratefull to hear from anybody that has experience with both

In water hunting (mainly salt water) the only Manticore coil I use is the M15, The bigger the coil the more area covered. I also use the Excalibur with the 15 inch WOT (Wonderful Orange Thing). I also have 4", 5X7", 18" and a few other sizes for different detectors ATX, ATPro, Infinium, Fisher X8, Detector Pro, Tesoro. Each combination has found it's own unique environment to be used in, from the depths of salt water to fields and forests to home attics.
Yes, attics; I have found and returned 3 wedding bands while swinging a 4" coil over insulation and in-between attic joists.

M9 has my vote hands down. Best combination of separation and depth.
