I don't know if anyone has had this issue with the locking mechanism on the E Trac, but the top lock that is on the unit has decided to not keep the shafts secured to the unit itself This is also where the internal connection is made. You don't want that part slipping out when you detect lol So being the simple guy I am , I duct taped it....what, doesn't duct tape fix everything?? Well it worked until last hunt and I spent most of my time putting the shaft back in with every other swing rofl So I found a quick, good way to fix it since I can't get myself to send it in, cause I'd miss it dearly I took some self adhesive aluminum tape (real aluminum not plastic) like you tape up duct work with or pellet stove pipes and folded over a small piece. I opened up the cam lock and put it inside to give it extra the thickness it was lacking. No the cam pushes the aluminum shim against the plastic part that hits the shaft. Now it is tight and does not move. Just a quick fix if you ever need it.
