The dive shop located in the Lumber Yard Complex and it is $50.00 for the week. The equipment is usually in good condition and they give you a carry bag for each rental.
Everyting at Gallows Point rents equipment. I think the sign outside said it is $20/week, but you might want to call them and double check, since it seems odd that their price would be so much lower than another place on island.
It's like looking in your soup and finding a whole different alphabet.
I rented snorkel equipment from Hurricane Hole (I think that's the name) in Mongoose Junction. Equipment was in very good condition and a full set was $6 a day.
