Questions and Answers for Submersible Systems 1.7 Cubic Foot Air Xtreme:

  • lani:

    does it come profiled with air?

    Bob  (Certified Scuba Instructor at


  • Peter:

    This says, "Not for SCUBA or snorkeling" and further down says, "can be used for SCUBA and water sports". Im snorkeling and looking into some type of emergency air. Dont know if a pony tank would work or this?? What do snorkelers use, anyhow?

    Darrick  (Certified Scuba Instructor at

    Hello Peter, yes this would work for you in an emergency. Since this does hold compressed air you would need a scuba certification to get this filled at your local dive shop.

  • lani:

    will the Spare Air, 1.7 cu. ft. Package be rugged enough for a rafting guide or is the extreme sport designed for rough impact?

    Darrick  (Certified Scuba Instructor at

    Hello Lani, this unit would be ideal for you. When you just need to help upright your raft or if you get knocked off the raft and you are pulled down this would give you the time you needed to recover.

It varies based on an individual’s lung capacity, approximately 10-15 breaths on average. It will give you enough air to get out of an emergency where you are held underwater for a short period of time. See specifications for more details.

How much does it weigh?

At only 2 lb. (for both breathing unit and vest) You won’t even know you are wearing it!!!

Do I need training to use the product?
