hi everyone,thought id better introduce myself,into all kinds of hunting,got 1 lurcher ,a hutch full of ferrets and a pcp,and a shed load of longnets,lol...
which won't happen with a mk3 because of the frequency it uses (although your mobile will interfere with a mk 3 if it's within a few inches of the locater)....you will however experience problems with the new crappy oversized magnetic collars, usually reduced signal if around metal fences or ground with a high instance of metals or even more usually a signal that is very erratic......in my experience that is
batteries for the old collars are 394
and for the new collar are 393
the batteries MUST be silver oxide NOT alkaline
knocker mate,i think youll find the batteries are 393
