The pump has a Dual Chamber construction. It’s 100% faster than a single chamber pump, and saves your efforts when going paddling. The paddleboard pump has Triple action modes to use at low, medium and high pressure conditions to maximize inflation efficiency. The pump is easy to pack and transport thanks to the detachable handle and base, which can be attached to the pump body when disassembled. The included hose fits the Halkey-Roberts valve (commonly used on inflatable paddle boards). High pressure gauge reads up to 29 psi.
