Purchased for use with my Eddyline Equinox kayak, this pump has been effective in emptying the cockpit quickly and easily. I kayak in the bay at San Felipe, Baja, Mexico several times a week, and the wind often comes up during paddling trips. That means that surf churns up lots of sand which ends up dumped into the cockpit along with water when launching or landing. A pump which could be easily disassembled for cleaning was a must. This pump suits my needs well, clearing the cockpit of sand-laden water quickly. Once back at the house, the pump body can be quickly broken down and rinsed clean of sand and made ready for the next trip.
