I have a little electric saw I use for climbing and trimming at the chipper.
It's nice for climbing because I don't have to fuddle with choke, prime, recoil start, warmup, etc. I unlock the brake on the electric saw and pull the trigger. I also feel it is more forgiving than a gas saw when it comes to nipping a rope or lanyard. The chain spins slower (but it has more torque from that electric motor) so it would not have the same potential to cut through a rope from incidental contact. Just my opinion and reasoning. However I will admit I've had to go down for a fresh battery without a groundie there. Thank God for SRT.
I also use it when I'm chipping because I don't have a huge chipper and occasionally something needs a trim before going in. It's so rare I don't want to run a cold saw at full throttle for one quick branch and then shut it down. Too much wear on a gas engine and again, its nice just to pull the trigger and not mess with pull cord and all that jazz for one cut.
