Telescopic. I have two--one is the twist to lock--and it is about 8 feet long. The second is the push button, and has push button end attatchements, which will allow brush, boat hook, happy hooker, etc on t, he end.
The twist to lock is faster to use, the button lock is more versitile. There are times when two boat hooks are good--like some of the narrow slot canyons of lake Powell...
