Does it take a long time to set up the Horizon to dive?
No, the Horizon was built to be easy to use and easy to set up! As with all diving, you have to give yourself some time to set up and check your gear, but experienced Horizon divers can set up their unit in about 15 minutes.

Does it take a long time to breakdown and clean the unit?
No, the Horizon does take a little longer than traditional SCUBA gear to clean, but the whole process takes about 15 minutes for an average dive.

Do I need special tanks to dive the Horizon?
No! You can dive the Horizon with any nitrox tank above 30% so it's easy to rent tanks while abroad or borrow a tank while on a boat trip. This is a unique feature of the Horizon system that makes it easy to dive!

Can I travel with the Horizon?
Absolutely! The Horizon was designed for travel! The unit weighs less than 40lbs and can fit in a standard suitcase that meets airlines requirements. Since you can use standard tanks, you do not have to worry about bringing tanks with you!

Are rebreathers more dangerous than other SCUBA?
All diving comes with risk, but the Horizon has several features to minimize risks to a diver. The Horizon is built for recreational use and helps divers make safe dives!

Do you really see more marine life?
Yes! You will be amazed at the surreal calm and quiet of the underwater world!
