Saw a youTube video very deep on small coins but you have to have clean ground I would think

Richard I have the Nokta FORS CoRe and will be using their large coil today and will report back on my relic findings. I realize it might not be the same as the coil for the racer, but hopefully I can help somehow

[size=large]I got one too but I can get a shovel in the ground over 3-4 inches..

Richard, I used mine on the CoRe yesterday and had a very hard time pinpointing when I was going after this target. Stock coil and pinpointing, no problem. But I need to learn where to pinpoint on the big coil...
Anyway, so I hit this valuable bullet with my shovel :-( BUT I WILL SAY THIS...This sucker was down a good 11-12 inches and about blew my headphones off. It sounded and TID like a large can, or belt buckle!

Richard, I used one on the core and it was the nicest, lightest, quality15" coil I ever used. Only used it once but got some deep keeper round balls in a pounded place. Sold the core and I can't use S rods with stock much less with larger ones so never would try it. Should work good if you can tote it.

It seems Makro has some work to do on their pinpoint technology , as it's abismial on my stock 11" DD IMHO, I wonder if it's a coil issue or different software revs. I'm pretty surgical when pinpointing on my F75 w/the 11" DD, so not sure what's different on the Racer?
I find using the old school technique of slowly zig-zagging the coil over the target until it stops an audio response, and then doing it again at a 90 degree angle to X the target seems to work better then the actual electronic pinpoint on the Racer 11" coil, should work OK on the 15" big boy too. Pinpoint works fine on the 5" coil as it's so small.
It only takes a little time and patience to master. They do have one thing in common with most Concentric search coils, and that is the target, if everything is of a favorable shape and position/orientation in the ground, will tend to pinpoint dead center. That's the relationship of the farthest functional-point in the EMF and where a target might be pinpointed.
Naturally, the size of a target can make a little difference, but for commonly sought targets that are of a roundish shape, such as most trade tokens, rings and coins, they should be isolated to about the center-axis of a search coil as long as they are laying in a flat-to-the-coil relationship. If they are on-edge, or if they are significantly canted to the left, to the right, to the front, to the rear, of off to any other angle, then that is going to throw the pinpointing off from the center-of-axis line to some degree with any type of search coil.
I know, I know ... somebody is going to say they can pinpoint off the toe or heal of an elliptical Double-D coil. Well, if a target is relatively shallow you might come close, but for maximum accuracy in making a close to perfect pinpoint, you have to have the targets of a proper shape and position, then do you best to isolate it with the coil's center axis point. This is generally much easier with a Concentric search coil, but can be mastered reasonably well with an elliptical [size=small](or round, but mainly elliptical because most DD's are)[/size] Double-D type coil.
At times I have to use a left-and-right movement in the All Metal or Pinpoint mode to narrow down a "line" from front to rear with the strongest response, then turning 90° [size=small](at a right angle to the line)[/size] and pinpoint left-and-right again, along that line, to find the strongest response in the center-axis of the coil. Sometimes I can just detune the audio of the Pinpoint response and get very close w/o having to turn myself from an initial position. It's all a matter of learning and mastering the detector's operation, knowing how to de-tune properly, then being patient and working at isolating the weakest, yet functional, pinpoint response from the target.
I still prefer a good Concentric search coil on most detectors for most hunting applications, but ... some makes don't provide such a coil, and some Double-D coils seem to handle the task at hand sufficiently well, so it's best to simply master what we use.
