Rating: TUSA Zena Air DIve Computer
Reviewer: Arijit D.,
An excellent product. Got much more than what was advertised. The deep stop and safety stop features are really great. The audible alarms and back light are very helpful. Must have for entry level - intermediate level divers. The pricing is fantastic, great value for money.

Rating: TUSA Zen Air IQ-900
Reviewer: Martin D.,
The most advantage of this dive watch is that user can change the battery on his own. The digits are big enough compared to the watch size to be easily seen even in the Black See deeps. The free dive mode is excellent. Disadvantage of the free dive mode is that the history can only be viewed using the data cable.

Rating: TUSA Zen IQ-900
Reviewer: Tanya I.,  - View all my reviews
I recently used this computer for my dives. It works perfectly! The computer is not too big and convenient to wear, it has large clear screen and shows all the necessary info easy to read. It goes with all the necessary presets including water activation, but I cant say its very easy to change settings: I had to read a lengthy instruction. Overall, I really enjoy it and I would recommend it to a friend.

Rating: Need a back-up
Reviewer: Peter Z.,   
I purchased one of these for myself and use it mainly as a back-up, this purchase is for my wife so she now has a back-up. We use the Wisdom 3 as our primary dive computer but we had one fail during a trip Hawaii. I carry an analog depth gauge with pressure gauge just in case. The Zen allowed me to continue diving with Nitrox. The Zen is easy to use and doubles as a time of day watch plus the display has large numbers.

Rating: great dive computer
Reviewer: Cesar A.,  - View all my reviews
i bought 2 of this for a diving trip one for my wife and one for me, it is easy to use once you understand what you are doing (read the manual and take the online course first) it guides you to safety with the audible alarms. i used it with the conservatism level on and still have great dives. absolutely recommended.
