Although I don't have one, the NEL coils are wound to be specifically compatible with the AT Pro OR the AT Gold, but not both. You have to specify when you order.
Contrast that to Garrett's offering which is advertised to work on both machines. That tells me the stock AT PRO/Gold coils are wound to be a compromise between the two machines different operating frequencies with slightly degraded performance.
I may have to try out the NEL sharpshooter which would be similar to the 5x8 in size.
I had the ATP and the ATG at the same time and the coils are interchangeable didn't notice any degradation between the two stock coils using them on either machine and also air tested to compare just for fun.
