Which Search Coil Are You Currently Using?

[John-Edmonton]

I cut my teeth to metal detecting way back on the Garrett CX model, GTA, GTI, Ace Series, using concentric coils. The older models used the crossfire coils, which really worked great. Garrett then designed a new concept of DD coils which were and still blunted on both top/bottom, giving superior depth over previous DD models. In my fairly mild dirt I prefer the concentric coils over the DD coils, as they tend to get more accurate ID, especially on bottle caps and twist tops. I get better depth with the concentric coils 9" x 12" Concentric vs. 8.5" x 11" DD, possibly because it is slightly larger. On the downside, I have to do more narrow swings to cover that hot spot on the concentric coils, especially if I grid an area. I also find it easier to pinpoint with concentric coil.

To me, the ability to pick out good signals amongst a lot of trash is not so much different between the 2 types of coils. The best separation coil is always the smaller coil. And the 5" x 8" does a great job at that.

I am going to get a 6.5" x 9" PROformanc concentric coil and do some testing with it. I am interested to see if in fact I get better results with the 5" x 8" DD coil, which I use often, especially when hunting in the woods vs. 6.5" x 9".

I love using the 6.5" x 9" concentric coil in parks using the ACE Series.

If anyone has any experience using any of the after market coils, it would be interesting to see how they work on the AT Series, especially on the latest release.....the AT Max.

prophylactic coil? Oh PROformanc. Whew!

I've always used my 5x8 on the AT Pro. I've got both small coils for my Racer 2 & Impact but wasn't impressed with either.

5x8, 8.5x11 and just got a NEL Storm

Beginning with the stock coil for now...may add a few in the future.

I had the 8.5x11 the other day but the love of my life (5x is back on

Have the 5x8, 6x9 and the cors 6.5x9.5 which took a dump . I was really liking that coil too. Currently I have the Garrett 6x9 concentric coil on the at max. Starting to like it and I can pinpoint with it just like a dd coil. Haven’t used 8.5x11 stock coil. Still in the wrapper. I hunt real trashy sites so I haven’t used it yet.

I ordered a 6.5 x 9 concentric coil and am looking forward to trying it out.

Sure is alot of Nel/cors coils failing.. mine, yours, and have read several on the forums. Can't remember if I ever had a detech coil fail but I've had a couple Nel coils fail..

 

[Albert]

Yes . The problem is you have to send them back to Ukraine or wherever they are made to have them repaired. Cost more money and time than to just throw them in the trash . I’m going to try and stick with oem coils

I put the 5 x 8 coil on my pro about 700 hours ago and have never taken it off. I detect mostly sports fields, parks and curb strips, with a little desert gold prospecting thrown in just for kicks. This coil has found 75 rings, and 1500.00 in clad over this period.

The AT pro to me, is the best bang for the buck you can get in a metal detector. Once you become one with this detector, the sky is the limit. You will know beyond any reasonable doubt when you are one with it.
