Throw away your bait pump. The Sonubaits Pro Expander pellets don't need any bait pumps to create the perfect expander pellet.
These pellets were designed by England International and world-class angler, Des Shipp. Des wanted an expander pellet that would stay on the hook well, and that every pellet you soak, created a useable hookbait, which wasn't the case with most expander pellets on the market. After lots of testing, differing processes of pre-pumping, and fishing tests, they managed to create an expander pellet that Des was happy using for all of his soft pellet fishing.
