That goes for both the 7" for the Nokta Impact and the 7" for the Makro Racer 2. Those are the regularly-mounted coils, as my choice, and the smaller 5" DD for really dense iron contaminated sites on the Impact, and 5" DD or 'OOR' DD on the Racer 2. Since I am almost always working trashier sites, and I need to/want to keep the detector and coil package light weight and handy, and those are the only two coils I need for those models. I never make use of the bigger-size standard coil.

I got the 7" Concentric for the Impact first, and after hunting two or three really terrible iron plagued ghost towns, I just had to get one for my Racer 2. Coin Hunting or Relic Hunting, the 7" Concentric is tough to beat!
