Congrats! Please tell me how you like using it once you get out in the field with it.
When I got mine in the fall I took it to a place with high target density (trash+coins together), a place where the stock 11" Nox coil was having a hard time separating. Maybe I started in too challenging a place, but I observed two things that concerned me: it wasn't giving the cleaner separation I was expected, and the sounds+target ID's were not very consistent with what I was used to on the stock 11" coil.
After this initial experience I tried it at a cleaner park and, sure, I could find coins with it - but again the sounds+ID's weren't exactly what I'd come to expect from the Nox.
Across all my fall detecting outings I used it maybe 5 times, but ultimately went back to the stock coil - and now I'm not sure what to say about the 10x5 coiltek.
I'll go back and do more reading on it, but I got it to help with better separation in target dense sites. Maybe I need more practice with it - could be that simple.
