Personal Transponders - which one ?

[Dynamite Arrows]

Hi ,

I have two original AMB PT s with breaks in the leads, I know these can be repaired , - however , if I want a new PT , which to go for ?

MRT PTX or AMB Harry ?

Is there a drawback to the current MRT ? Does it work with any AMB system RC3 and RC4 ? at around half the price of an AMB Harry for a heatshrunk MRT , is there a practical advantage to go for the Harry ?



thanks
