Thats what Ill be saying to my buddy, next time they run out of air. Once theyve tried this octo theyll want to be buddy-breathing all the time!! While I havent had to use it yet, Ive used it on a couple of dives as my reg (just to try it out!). Super comfortable, effortless breathing. Not the cheapest octo on the market, but worth every cent I paid for it!! I would reccommend everyone buy this octo - you will not be dissapointed!!

Questions and Answers for Hollis 321 Balanced Octo:

  • james:

    I just bought the Hollis 321 mouth piece and hose but i guess i need to by the regulator part and yoke too? Is that correct? Or is the regulator in the mouth piece?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello James, if you got this octo, it would come with the hose and mouth piece. Since this is the secondary part it would not come with the 1st stage part. You would need to order the http://www.scuba.com/scuba-gear-36/033189/Hollis-221-DC-3-Balanced-Regulator.html to get the 1st stage and primary regulator. If you would like to place an order or have any other questions please feel free to give us a call at 1.800.347.2822.

  • Vadim:

    Hello Sir! My name is Vadim. I live in Murmansk in Russia. Id like to buy in your shop Hollis 321 Balanced Scuba Octo and Sherwood SR1 DIN Scuba Regulator. I see, I can use Sherwood SR1 DIN Scuba Regulator in cold (ice) water, but I dont see it for Hollis 321 Balanced Scuba Octo? Thanks for Your help.

    Bill  (Certified Scuba Instructor at Scuba.com):

    If the regulator is going to be used in "ice" conditions the Mares Proton Metal would be a better choice. http://www.scuba.com/scuba-gear-33/035033/Mares-Proton-Metal-Octo.html
