Has anyone had a look at what they call the auto tether type systems. Think wireless kill switch, basically if you get more than 20 or so ft between the reciever and sending units it kills the engine.
I guess a possible benefit to this type system (in addition to not needing a physical tether) is that you can have multiple sending units.
Just curious if anyone has used and what there opinion is.
something like this.
