Last week I got my x35 coils and I installed v5.1. Went out for a few huntings but I noticed the connection between the coils is falling away from time to time, the coil is running much more unstable than the original (old version) LF coils on the very same fields and spot. I reinstalled v5.0 to check if it that may solve something but unfortunatly it didnt fixed anything. Already contacter my retailer but he is enjoying his holiday at the moment. So I was wondering if others experience the same problem and if it Just might be a software issue?
