1 tank boat diving

[dashark]

Ramon's villiage on amberguis caye, Belize does 1 tank dives all day long. most of the sites are only 5-10 min away . most of the boat rides are within the barrier reef as well.
You could do 2-3 dives a day there and do your surface interval at the resort.
Or go someplace where the shore diving is good....

Many operators on Bonaire, including Captain Don's and Buddy, offer boat trips that are almost all one-tank trips. Most also offer "dive and drive" packages in which you can get a certain number of boat dives and unlimited shore diving with a vehicle included.

Grand Turk is also a good place for one-tank boat trips as the sites are close to shore (although not generally close enough for easy shore diving).
