I'm ready to pull the trigger on a small coil for my Racer2.
Have you made the coil decision yet? I am, and have been since June of '68, partial to smaller-than-standard size search coils for most of the site I hunt because I deal with trash ...
dense trash ... with ample iron debris in the mix. I also hunt sites where I deal with building rubble and heavy vegetation so smaller coils work better.

Per a rep at metaldetector.com, the only difference between these 2 coils is the physical size difference.
It shouldn't take a rep much to figure that out just by looking at them! The
'OOR' [size=small]
(a name I started using on the forums to describe the slightly 'Out-Of-Round' search coils years ago)[/size] was listed by Nokta/Makro as measuring 4.[size=small]7[/size]X5.[size=small]2[/size] inches. The other, that they call a 5" DD coil, measures about 5¼" across the center axis of the coil not counting the thin coil cover. It is a round shaped coil
On my Nokta Impact and one of my Relic units I keep a round 5¼" coil mounted for very littered sites, and there is no
'OOR' coil made for them.
On one of my Nokta CoRe units I keep the
'OOR' DD coil mounted full time3. There is no round 5¼" coil made for it.
On the Makro Racer and Racer 2, both sizes are compatible and interchangeable, even though the website only shows an
'OOR' for the Racer accessory and a 5¼" for the Racer 2 accessory small coil. So, with the original Racer or the Racer 2 the consumer has an option. I had BOTH the
'OOR' and 5¼" DD coils ...
my preference was the 'OOR'.

Has anyone done, or know of, a side by side comparison of the RC13 and RC13E to verify?
Yes, I did a lot of in-the-field comparisons with both of those Racer accessory small coils and compared them along with the CoRe w/
'OOR' and Relic w/5¼" and recently with the Impact and 5¼".
Dave_E said:
Do they really achieve the same depth and target separation?
Both coils, on either Racer, will provide depth of detection that is much better than anyone would expect such a smaller-size coil to achieve. 'Depth' however is not a strength we usually expect from a smaller-size coil and, at times, such potential can work against us in some metal contaminated environments. Smaller coils are at their best working in and around metal objects, brush, structures, and isolating smaller-size targets in amongst masking trash.
Both of these coils can provide closely similar in-the-field performance, but depending upon what the particular good-target/bad-target challenge is, one might show and advantage over the other. in a couple of very challenging side-by-side comparisons, the round 5¼" coil had a slight edge in performance over the
'OOR' coil. But overall, I still prefer the
'OOR' coil, and it will have it's strengths shine at times as well.

Are the ears the same quality?
I would say so, and I have never had a problem with any of the more recent production Nokta / Makro search coils.
Dave_E said:
Coil cable length and quality the same?
Close enough that I don't bother to measure them.
I will comment on after-market search coils. Personally, I have never really been too impressed with some of the coil offerings made by a non-detector manufacturer and have always favored coils made by the detector manufacturer. That said, if I had either a Racer or the newer Racer 2, and all I had was the standard 7X11 DD and no smaller-size coil, them my choices today would be amongst three coils. The Makro
'OOR' coil, the Makro 5¼" round coil, and the NEL Sharp round coil. I guess I might add the CORS Point which is essentially the same coil from their sister company. I was very impressed with the performance it provided even against the two Makro coils ... most notably on a smaller-than-average size coin challenge on the
Nail Board Performance Test. On common US coins I prefer the
'OOR' coil in trashy environments, but a very close 2nd choice would be the 'Sharp' and then the Makro 5¼" DD.
