Sounds like the one I have (around $150?). Works well, sometimes will slip and shorten if you dont do a good job locking the pole. It is barely enough pole for my boat though. I really could use a heavier pole for most any time it is extended past about 10-12 feet, as it will sag in the middle, and I just know it will break someday if I am not careful to not overload it.
I am using the mobile app now so I can't see what size boat you have, but if it is smaller than mine it should work well, if only a little larger, dont extend past 12ft and it will probably be alright.
