"I, Snorkel Bob, present the best dive gear in the world, bar none, and I, Snorkel Bob, warranty it for 2 years (save your receipt). Serving 2 million snorkelers through the 80's and 90's and now the 00's with snorkel gear makes me, Snorkel Bob, different from the shirts in Chicago, LA or Tokyo, with their 14 floors, receptionists, secretaries, water coolers, coffee makers and don't forget the dictation. It's a dozen stressed engineers who last saw 8 hours of sunshine in a row in grad school, now testing theory in a swimming pool. I, Snorkel Bob, know what's best by listening to the wants, needs and satisfactions of you who want to breathe easy in the fluid dream."
Thus reads the advertising of Snorkel Bob, island legend and all around wacky guy. Snorkel Bob doesn't just talk a good line though - he rents (or sells) a quality product at an amazingly low price, makes it easy and convenient, and even throws in some freebies! ("a Freebie for You, In Appreciation of Behavioral Patterns Propitious for Me, Snorkel Bob.")
Snorkel Bob is reliable, cheap, and ubiquitous. You can pick up your gear on one island and drop it off on another. For the ridiculously low price of only $9 per week, you get a nice set of mask/fins/snorkel PLUS a mesh bag to store it in, a container of mask goop, a fish ID card, a map, and Snorkel Bob's very own tip sheets for the best snorkeling beaches on the island. And best of all, Snorkel Bob rents prescription masks for the visually challenged who forgot to bring their contact lenses along, like me!
They also rent boogie boards, beach chairs, and other beach-going goodies. You can buy inexpensive underwater cameras, and even book boat trips.
I, Truly Malin, heartily recommend your friend, Snorkel Bob - and I don't even know the guy!
Open 8-5 daily (but you can drop off your gear after hours)
Also located in Koloa and on the other islands.
