When the fence was originally introduced on one occasion due to a certain need i forgot to turn the fence off at the 100km comfort break , booted half the group.
It went well… 3 got fired from the canon and then everyone else relaxed and sat back with the beacon. I actually only needed to use it sparingly after a couple of sprints rather than the entire ride.
After this my first lead with the “Bug Zapper”…I’m giving it a thumbs up.
