My old Henderson Marine pump had a 3 foot long hose and needed to be filled with water before being able to pump anything .
---> Oh what a joy this pump is - compact - perfect hight for a sea-kayak.
Powerful stream of water streightaway.
It even floats do to high visibility foam floatation.
Found a small eyelet near the top - so now it is tied to the boat with a fixed length cord.
I'm been extremely pleased with my new Harmony bilge pump. It's one of those necessities that you carry but don't think about until you need it. On a recent float down the Duck River we had a boat swamp and I was amazed how quickly I was able to get the water out of his boat and get him back in it. One of the best investments I've made.
My friend was paddling in a borrowed kayak and his kayak had a slow leak. I let him use my Harmony bilge pump and it worked great. It's lightweight but very powerful. It pumps out the water in seconds, not minutes. I'm very happy with my Harmony!
This is a fast pump. Even people who have regular pumps ask to use mine because it pumps while moving up and down.
Works like a champ. You could use it empty your bath tub.
