Flungdung
You've been out of Oz too long to remember the distances! You are right about those machines but they don't do surf patrols at a max height of 200 ft behind the surf well out of beach auto range & on one occasion 30 miles out to sea because the Lismore machine declined to go. The SLSQ machine is still a non float equipped 350 & will remain so despite the other machines you mention.
