I have used this type of Telemetry since the beggining of the 90's and its never missed a beat! boy thats tempting fate .
I use a couple 3v XLF-3 Transmitter with it which also touch wood have never let me down, this telemetry has been chucked on the floor, slid off car roofs when I drove off and forgot about it and basically been pretty knocked about over the years but always came good, I can honestly say its been used every season since I owned it, the only thing I have added to it is a Pre-Amp filter which does what it says on the Box! it amplifies the signal and also filters out alot
