Good to hear you found a good combination of machine and coil that works best for you. I have heard of the NEL coils being the best aftermarket ones out there for several different machines. I have the Hunter and the Attack 3 frequency on order for my X-Terra which should arrive in a couple weeks. Can't wait to bolt them up and give them a go! The former soviet countries are known for their technology hacking and improving on things, so it's no surprise that NEL coils come out of Kharkov Ukraine. If I had been into detecting a couple years ago, I could have stopped in and bought one direct when I was in Kharkov.
