Rating: Great Computer!
Reviewer: Megan F.
I bought this computer for my best friend for Christmas! It was an instant success! We had a planned dive trip the next week, so she got to use it right away...she has an older Tusa dive computer, so it was an easy transition to the new one. Thanks for quick shipping and great customer service! Megan

Questions and Answers for TUSA IQ-950 Zen Air Integrated Air / Nitrox Hoseless Computer Watch:

  • Ralph:

    Does this item come with the transmiter, or does it need to be ordered seperatly?

    Bill  (Certified Scuba Instructor at

    The Tusa IQ-950 comes complete including the transmitter.

  • Kelly:

    Thank you, but if I make a purchase, does the package come with 3 transmitters?

    Aaron  (Certified Scuba Instructor at

    It only comes with 1 transmitter.

  • FRANK:


    Greg  (Certified Scuba Instructor at

    No, the TUSA IQ-950 does not include the compass function. I would suggest the VT4 Air / Nitrox Hoseless Wrist Dive Computer with Digital Compass.

  • Scott:

    Is it possible to buy the watch without the transmitter? If so how much would that be?

    Bob  (Certified Scuba Instructor at

    Unfortunately no it is not offered without the transmitter.

  • allan:

    sorry for my mistake, my question is dose this computer can be d firmware by myself use the tusa usb cable for this computer ?

    Darrick  (Certified Scuba Instructor at

    Hello Allan, yes the firmware is updated on TUSA website. So when they up-date the software you can go to there website and download the up-date.

  • allan:

    dose this computer can be firmware by myself use the usb cable ?

    Darrick  (Certified Scuba Instructor at

    Hello Allan, this is a special type of USB cable so not any UBS cable will work. If you want to download your dive onto your computer you would need the download cable for this computer.

  • robert:

    Can the IQ-950 Zen integrated Air/Nitrox hoseless computer dive watch be set to display depth in meters instead of feet?

    Darrick  (Certified Scuba Instructor at

    Hello Robert, yes you can switch your computer from imperial to metric as a push of a button. But that will work with any computer.

  • rob:

    I did not recireve a manual w computer. Can i download one?

    Bill  (Certified Scuba Instructor at

  • Kelly:

    What is the max depth of the dive watch? and does it come with 3 transmitter or 1 (I understand it can track up to 3)?

    Bill  (Certified Scuba Instructor at

    Yes this will track up to 3 separate transmitters. The computer is designed to be used for recreational depths up to (130ft.), but typically most will monitor up to 200ft.

  • Jeff:

    Is the soft ware Mac compatible?

    Bob  (Certified Scuba Instructor at


  • Ton:

    Dose the transmitter fit Atomic B2s 1ST stage? Need an adapter? It needs adapters for Tusa R-200 and R-600 1ST stages.

    Darrick  (Certified Scuba Instructor at

    Hello Ton, 98% the manufactures high and low pressure port are a standard size. Yes the TUSA transmitter will fit in all of those regulators without an adapter.

  • Chemy:

    Why the price in the product description is 899 and in the cart is about 500?

    Bob  (Certified Scuba Instructor at

    We have absolutely no idea. When we test it the product comes up at the correctly. Our advice would be that if you are interested in this item, GRAB it before what ever anomaly is causing it to show as a lower price goes away.
