Is there any place in or near Kona that has weekly unlimited tank rentals like they have in Bonaire? We plan on shore diving mainly and would like to be able to grab two or three tanks each and head out to dive. All of the dive shops I have seen so far are priced for one tank and you have to bring it back each time for a fill. This would be inconvenient and waste a lot of time not to mention renting two or three tanks each over a weeks period would be extremely expensive.
