I DO like my kill tether! Had a friend and his wife get thrown out of their boat last year up from the sand bar when they were cruising at 50mph with no traffic. They did not have a kill tether at the time. The boat cicled them like a shark about to attack for quite awhile until a passer by plucked them out of the water. They followed their boat running in circles at 3/4 throttle as it made it way downstream with the current. A couple of patrol baots finally ran it aground with no injuries to anyone in the end. You never know when a new sandbar that was not there last time out will GET YA'.
