Shooting my Vertix yesterday from my tree stand 20'+ up only to hear a clang and seeing the harmonic dampener with barbell bounce off my platform and disappear into the leaves. NOT found Call my local shop to get a replacement (not warranted WTH ?) and none in stock. $40 for a replacement, and also said I'm not the first to have it happen. Say some guys are using a small zip-tie to keep it from being lost if it pops out. I think I'll use a little RTV to "glue it in". SO...keep an eye on yours.
