Really nice folks. They do a special if you rent 10 tanks in advance, an electronic card.A good place to rent gear on the Lahaina side is Aloha Maui Diving and Westside Air (same place); Closed on Sundays. Check as their hours can very. Contact: (808) 495-9559; 130 Kupuohi St D4, Lahaina, HI 96761. This shop is terrific! They never give grief about solo diving, and they have free weights they will rent. Many will only rent integrated weights.
