5" Racer 2 coil not very deep

Jack I re-read you comment, are you saying that on the R2 that the new 5" coil is way deeper on the R2 then the OOR coil? Like the OOR is best utilized on the R1 and the new 5" is best utilized on the R2?

Thanks,
Brian

Brian that OOR coil is surgical as it gets, I just received another as to this coil is going to have a cult following for those that realize what it can do. The 5" is way deeper than the OOR and almost seems for a lack of better words unteathered on the R2 in deep mode. Physics I don't know but these sure seem to defy the standard logic behind coil size and depth. I've worn out some places with the 5" coil then put the OOR on and dug some more in the same spot, all involved with trash. I think the big thing with most not getting any depth is they don't know what to listen for or better yet they rely on numbers way to much. Both come into play most of the time but the blending is what confuses a lot of the new users.

Lot of variables to factor in, but in order to achieve maximum depth you need to have minimal to no EMI and maximum gain. I have dug 8-9" (measured) coins with my OOR RC13 DD 13 cm x 12 cm (5"x4.5") coil on my Racer1. I don't have (or see the need to obtain) the new 5" coil that came out with the Racer2, but it's possible it may not be as deep as the OOR coil?

Also I believe that a coil can go no deeper then it's width is purely urban legend, I've dug plenty of targets that were far deeper then the width of the coil. What's the logic (or physics) to support such a claim?

hh,

when I read Tom's comment:

Tom Slick said:
[size=medium]Honestly I can't really tell the difference between the two.[/size]
That is exactly how these two coils have been impressing me, and I own and use both. I have the 4.[size=small]7[/size]X5.[size=small]2[/size] 'OOR' coil on a Nokta FORS CoRe and on one of my Racer 2's, and I have the 5½" DD on another Racer 2, a Gold Racer, and my FORS Relic. I've been using all these coils in the same densely littered, iron infested old Relic Hunting sites as well as in urban Coin Hunting applications ... and if there is any real notable differences it is only in how we happen to picture EMF's in our mind from visual observation about 5 to 6 feet away. They work essentially identically.


Tom Slick said:
[size=medium]I think there is a psychological difference (at least for me) when using them in that you feel like you're getting better coverage with the 5.5" and you feel like you're getting better separation with the OOR. In actual side by side testing, and actual field use I think the results are the same[/size]
Yep, same-o same-o results for the most part. From ample time afield aI am very comfortable using either of them, and while I really,. really, really like the excellent looks and performance of the 'OOR' coils, I have come to more of less prefer the newer 5½" round DD coils. Again, part of that is just due to the fact that it looks like I am getting slightly better coverage.

Tom's has the same feelings I have. Take your pick, they are both excellent choices. :thumbup:

OK wheew!
Thought I was going to have buy the OOR too lol. I have the 5's on my relic and on my racer 2 on its way to me.
Good to know I have enough.... for now lol
 
I thought the OOR was no big deal until I cranked up the gain and it came alive! The glory of a small coil is EMI resistance and not as likely to commingle near metal items. Somehow the Racer OOR is something special. While not everyone discovers this, it is still very clear to those who have. So much so that I am reluctant to talk it up with those who hunt my dirt! :detecting:
 
The achillies heel for the racer is mineralised soil, i could get maybe 5' with my R2 on a big coin with the 5' coil, maxed out at 9' for the stock 11x7 coil (reading 3-4bars mineral scale) so as much as i liked the many features it had it lacked the one feature i really needed, depth in bad ground.
Some detectors get bad ground better than others and my current detector fitted with 5' coil nails the same coin at 9' (same as R2 with 11x7 coil) but if it was an air test competition the racer would beat it hands down lol

It's the Golden Mask 5, here's a short vid of it on a penny in my garden with 5' coil, its the same coin the racer was barely hitting with stock 11x7 coil, so i dug it up just to be sure of depth as it was a fair while ago i burried it.
 
since your comments about Racer 2 performance with a smaller coil sure don't match up with mine, nor a number of Makro & Nokta users I know and periodically hunt with.

Also, since you have no 'signature' to reflect any makes or models of detectors you own, and also noting that with this post it only makes a total of '13' posts on the Findmall Forums, I, like most readers:

• don't know much about you
• don't know where you are located [size=small](to hint of the type of ground environment you might deal with)[/size]
• don't know how long you have been using metal detectors or how frequently you hunt [size=small](are you an 'average' Hobbyist or an Avid Detectorist)[/size]
• and we also don't see what settings you are using with the Racer 2, nor the sweep speed or search mode you compared performance with.

I presume you mean 5 inches and 9 inches rather than feet.

You didn't describe what the "big coin" was, and that can make a difference is it is mostly silver or copper or ??? because the Racer 2 does operate at 14 kHz and that can be a factor on detection ability. Also, depending upon what your description of "mineralized soil" is, I will say most sites with a higher iron ground mineral matrix tend to be more challenging for almost all detectors than it would be compared with lower mineralized ground.

What was the Ground Balance reading for the specific site you used as a test comparison? Describe th4 search mode you used and settings, if you will, because I have had splendid results with both the 4.[size=small]7[/size]X5.[size=small]2[/size] 'OOR' DD coil and the newer round 5½" DD coil. I did view your added video of the GS5, and it also looked liken the coil was mounted backwards. Couldn't see the GB phase reference, nor other settings, and I didn't see the Racer 2 used in a side-by-side comparison.

Smaller coils are designed to assist us for hunting in and around brush and rocky, and working close to metal structures and dealing with highly littered sites. Also, smaller coils were not designed to provide astounding depth-of-detection. That said, I have had very good in-the-field results with both of these search coils. Typically we can expect to get coin-sized targets of 'average' size at depths usually comparable with the size of a search coil's diameter, although that has always been simply a rough guestimate of a coil's detection depth.

I have found quite a few long-buried targets, both Coins and similar-size Trade Tokens of various denominations and metal buttons with my Racer 2, and I have compared it against my other favorite detector models, on many of these located targets prior to recovery. I used the Nokta FORS CoRe that operates at 15 kHz using the small 'OOR' DD coil, and my primary-use FORS Relic w/5½" DD and it operates at 19 kHz.

I also compared the Racer 2's audio and visual responses on located targets against a few competitor's models such as a Garrett AT Pro and AT Gold with their smaller-size coil, a White's MXT Pro and MX5 w/6½" Concentric coil, and a Fisher F19 w/5" DD coil. This was in both relatively clean urban hunt sites ad well as the very iron littered ghost towns I like to hunt. I have been very impressed with the Racer 2's depth-of-detection with both smaller-size DD coils.

Again, I watched the video you posted of the other detector, but can't compare it with the Racer 2's performance because I don't know your settings used. I know the 5½" works for me, as well as the 'OOR' coil, and I should be off to an old site for some detecting tomorrow where I have confidence my Racer 2 and small coils are going to continue to work well. This year my old coin count with the Racer 2 w/'OOR' started with a silver quarter, but that was followed by three silver Barber dimes that were recovered from 5" to almost 7", all using a coil with a smaller coil diameter than their located depths.

I'll continue with my Racer 2 and trusted smaller coils,

Hi Monty,

I'm located in Northern Ireland.
Been hunting regurarly for 10 years, maybe 8-10 hunts a month, more in the winter, used mostly minelabs, ctx, etrac, 705 used others on loan, f75, T2, older vikings etc and recently racer2 which i had on pre order.
Settings with the R2, mainly 2 tone, or deep on pasture, iron audio 2, no notching, ID filter 5, tone break 10, gain 85+ where possible.
'Big coin' is a copper victorian copper penny, one of the most regurarly found coins in my hunting areas.
3-4 bars on mineralisation scale for R2, ground balance 65-75
Sold the R2, as did a few of my hunting buddies who got similar results, so a side by side video not available at moment.
Ground reading in the GM5 reads same ground as R2, mostly med-high, will do another clearer video to show.

I also hunt old sites, mainly from the 11century to modern 18th century derelict building grounds, so there can be several hundred years of iron and other items to contend with, also hunt old pasture that might not have seen a plough in decades, i don't hunt modern coins in parks.

In my opinion the R2 loses roughly 50% depth in my soil with the stock 11x7 coil, it hits the 'big coin' at 18'' in air and misses or barely hits it at 9'' in ground, better in all metal, the nel tornado hits it better but only just, the 15'' racer coil hits it well.
Keith Southern has got a video showing a similar result with stock coil in bad ground.
So in my humble opinion, yes the R2 has some cracking features and i guess in good ground it would shine and get good depth, but in my ground it's an average performer compared to the GM5 which slices through my soil losing very little depth compared to its air test value in both 8khz and 18khz, and it can hit the same'big coin' at 9'' with the 5'' coil fitted that the R2 struggled with!
P.S. the coil is fitted correctly in the video lol
Thanks Robert
 
Love the OOR, finds those hidden coins in the school break areas usually littered with pull tabs and wadded foil. Depth between 5-6, at best, but it makes it up in separation.
