Boat Fills
While the John Jack does have a compressor, the boat is not in the business of providing fills on day trips. If you have a problem or a special need, we will try our best to oblige you. If you will need fills on a day trip, you MUST make prior arrangements with the Captain. Fills on a day trip will cost approximately the same as a tank rental. The boat is not responsible for dives missed because of compressor failures on any trip.

Shop Fills
The John Jack has an affiliate business, Dive Gasses Unlimited. This fill station is located on Staten Island. We can provide you with any breathing gas you need air, Nitrox, Oxygen, Trimix, and Argon for suit inflation. This is where we fill the rental tanks. We pride ourselves on giving “good” fills, not inexpensive ones.
