Rating: Excellent regulator... Low price.
Reviewer: Alfred Clair Jr
Zeagle was a new name to me. Turns out they make excellent diving equipment. All American made in a factory in Florida. This regulator works beautifully. It was an amazing price too. Its not Zeagles top regulator, but its fine for me and the price. Zeagle does do lab testing and they publish all of the results. ALL of their regulators far exceed U.S. Navy required standards, for "Class A" regulators.

  • Kim:

    Does this item come with hoses?

    Aaron  (Certified Scuba Instructor at

    Hi Kim, This regulator with come with the hose that connects the 1st stage to the 2nd stage.

The ZX DS-V regulator outperforms many regulators with outstanding reputations- why? Among many reasons, two stand out:

It has an internal structure that allows direct airflow through the 1st stage, providing outstanding performance.
Zeagle’s conical precision high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.
Work of breathing at heavy* demand:
1.09 Joule/Liter
*198 (60M) depth, 750 psi inlet, 62.5 RMV (liters per minute respiratory volume)

Like all Zeagle regulators, The ZX DS-V comes factory ready for use with EAN/ NITROX to 40% O2.
