Shopper Will this fit onto an AquaLung Impulse3 Snorkel?
HAROLD E It's a standard snorkel keeper. Should fit anything near average.
MICHAEL W YES, it will work fine, just remove the lower FLEX tube and slip the Keeper in place much easier to remove from mask strap with this Keeper! Safe Diving!
JAMES P If you send the diameter I can measure for you.
DAVID B Can't answer as we use Impulse II's.
