electrical? battery powered? on a hunting bow?? novel idea....but i think ill pass..the catalog wouldnt fully download i could only see part of it...but the dont seem like it would work out well on a hunting bow...even if constructed super great...id like to hear from someone thats used one...and how it works etc..sounds way to complicated for a hunting bow...even if its simple for you...complicated electronics etc...in the rain...up and down a rope day in and day out...battery powered...nah..
