Just messing around, did test. Four coins a quarter apart. F75; one tone an FA. Nox 600, top speed 3. Legend = 10.

Legend couldn’t handle it. Nox and F75 close, slight edge to F75.

Tried X-Terra Pro, notably faster than all. I’m assuming this generation of Minelabs would all be faster.

I no longer own an F75. It doesn't like the high iron mineralization and high altitude EMI here in Colorado.

Anyway I do own an Equinox 600 and two Legends. I also own an XP ORX. 

I did your test or something similar over 4 coins that were one quarter's width apart.

Equinox 600, 11" coil, sensitivity 18, Park 1 multi, recovery speed 3, 1 tone: I could hear all four coins during normal full sweeps at 2" coil height over the targets. The audio was a little elongated but distinct enough.

Legend with 11" coil, sensitivity 18, Park M1, recovery speed 5 of 10, 1 tone: I could easily hear all four coins during normal full sweeps at 2" coil height over the targets. The audio was much less elongated than the Nox 600 tones. Switching to Pitch tone made that audio even easier to hear.

XP ORX with 9" X35 coil, sensitivity 90, Coin Fast, 14.4 kHz, 3 tones: the audio tones were amazingly short and distinct even at normal sweep speed.

So, I don't have any issues with your test. The F75 in FA was really fast from my memory of using it.

I do have an issue with you stating that the Legend couldn't handle it which is ridiculous from my simple testing even at recovery speed 5.

XP ORX comes in 1st by quite a bit. Legend 2nd. Nox 600 distant 3rd from my testing.

This next part is mostly for the OP or anyone that is interested.

I keep my XP ORX for gold prospecting and for hunting in thick iron trash where I need extreme speed, don't care about depth and I'm am basically digging anything that gives even a hint of non-ferrous. I don't use my ORX for normal coin, jewelry or relic hunting where I need depth and where I need target ID accuracy due to not being able to dig it all in someone's nice yard or public areas. Target ID accuracy and up averaging of low to mid conductor non ferrous targets that are more than 3" deep drives me nuts using the ORX or any single frequency detector here. For me the F75 was not as capable as the ORX. Iron mineralization here just cuts depth in half of what normally is achievable with single frequency detectors like the F75.

So, these latest simultaneous multi frequency detectors have made all the difference for me vs single frequency. They have wireless audio, waterproofing, excellent ergonomics, lots of great features including selectable single frequencies when I need them, plenty of speed, outstandingly accurate target IDs even on deeper targets and great sensitivity to a wide range of target sizes and conductivity when set on multi frequency. 

Like Chase recommended, I am not sure you need a Manticore although I love mine. But, there is nothing wrong with buying a Nokta Triple Score, Minelab X-Terra Elite, Nokta Legend, Minelab 600, 700 or 800 (deals right now on the 800 are incredible). I think the 900 is overpriced compared to the great deals on the Manticore right now. I wish I could recommend the Garrett Vortex but it's just too early yet without more end user reports.

Any of the SMF detectors I mentioned above would be very capable gold prospecting detectors if they have dedicated gold prospecting modes or just using their multi 2 settings with medium recovery speed, low iron bias setting, all metal discrimination mode, conservative sensitivity setting and a good ground balance. Those that have 15 to 40 kHz selectable single frequency options would easily equal or exceed the F75 on smaller gold using similar sized coils.

Thank you everybody for your help. I've decided to just get the new 12-inch coil from Amazon for 190, and I also picked up the 6.5 in elliptical coil it's supposed to do better with discrimination, I found my F-Pulse was still working so I don't need to buy a new one and I found some old great ghost headphones so I'll use those and not the wireless Garrett...

Picked up a Black Friday shovel a sandscoop 

Doing another delivery today at a regular customer's house that's this nice 1932 building that's never been detected, I received another permission not only did detect the yard but also their basement if I like. 

I'm going to wait till I get the new coils and go dig up my Garmin camera, and I think I'll make yet another metal detecting YouTube channel with the tiny bit of videos I might have the time to make your and there.

It's not the detector of my dreams however, I know that it worked back in 2008 and 2014 I believe. Should still be functional better than none 🙂

I'm quite sure I have not even came close to using it to its limits. 

Perhaps you already know this, but if you haven't detected much in all metal mode on the F75, you might want to experiment more with that.

I've been impressed with how deep and sensitive all metal mode on the F75 and T2 is. I swing a Deus 2 but still love taking my F75/T2 to areas that I've hit hard. More often than not, I find a few keepers that I've missed previously. It's a great technique if your soil is highly mineralized, too.

This video shows you how to set either machine up in all metal mode:

Tried it again. Didn’t have Legend in Multi. That made the difference. The only thing I was trying to say, it surprised me that the F75 could hang with the others on speed in FA.

The original idea was to use the 18x4 coil for ground coverage. I ignorantly assumed I could get good coverage at about 18” a shot. It has tremendous width separation but very bad on length. If the area is sparse, killer combination. That coil has good park depth on the 75. However, if the area is a little trashy, you’ll be missing a lot of targets due to the length.  Found this out the hard way. Covered a lot of ground but got few coins. Put on smaller coil and realized I was walking over coins.

Sparse targets, killer combo. Even just light trash, you still have to take tight swings defeating the whole concept.

Hey that's a great video thank you. I was wondering if you ever tried the larger elliptical coil? I heard they have better separation? Yeah I like all metal too. I'm trying to get the sounds down that really helps I knew that that was similar for a higher ID items like coins you could tell when it doesn't drop on the coin but I didn't know that that would equate to iron on the all metal. Thanks for the info

You are right... the DD type coil is strongly affected in detection when there are more targets in the plane along the length of the coil... where the signal of a ferrous target can quickly cover the signal of a non-ferrous target...

But for example, the 18x4 "BigFoot" type coil which has a winding in the shape of an 8 /it is not a DD coil/ is really resistant to this phenomenon because both halves of the coil work independently of each other in separation...and can properly detect a non-ferrous target even if there is an ferrous target under the other side of the coil...

Otherwise, a single-frequency detector working somewhere at 14-30 kHz..can
Here the multifrequency detector has the upper hand..

As for modern multifrequency detectors... some of them have wide possibilities to work also on 1 frequency... which you can also change... and so for example optimize the detector for some type of detection...I myself use these possibilities a lot..
