Been using Walkers for yrs. Started off with one..went to 2..and back to 1.
There' s little tecniques you can use to tell directions using just one..just takes getting used to.
I wouldn' t go to the woods without mine..my ears ring 24hrs a day and can' t hear high frequency noises..without the game ear I don' t even hear birds chirp.
I also use the silicone ear plugs you can get in drug store..instead of the ones that come with game ear..the silicone molds to your ear.
