Comments about Tusa Zen Air Integrated Wrist Dive Computer (IQ-950):

I recently bought tis divecom in the store during my business trip in NYC. Upon unboxing back home in Malaysia, tis divecom is stuck perpetually in Dive Mode. Any attemp to change the mode (press de M Button) will induce the divecom to perpetually cycle through the 'normal/gauge/freediving' modes. The only way to bring it to Watch Mode is by removing and replacing the battery. When press M button again, it will jump on to Dive Mode and perpetually cycle through the 'normal/gauge/freediving' modes. Basically it is jam stuck in a perpetual cycle. User manual mentioned 'should not dive' with divecom if it doesn't perform to factory intentions.
I had excellent service from David and he is trying too help me sort out this mess. U should look for David when u r in the store. I can't bring it in for exchange as i'm now thousands of miles away. Hope to be able to test out Zen Air on a dive soon. Update u guys.

Questions about this item:

mike m  what is the size of the screen and bevel? thanks
Angelo F  It's a little bigger then a Casio G- Shock : but the number display slightly larger then g shock ... It is easy to read
Frank M  Would like a spare battery for the transmitter I also need a new o-ring when I replace the battery the item cr-2 does not specify if it comes with a battery if not what is the part # for the o-ring. ?
ACHILES B  The CR2 lithium battery does not come with an O-ring. It's a standard battery that you can find in most electronic stores and supermarkets. If the O-ring on the hatch is undamaged, there is no need to replace. I've changed battery numerous times and have not needed to replace. Just make sure it's properly seated before replacing hatch and you may need to lubricate.
Catherine T  Since the price for the IQ-950 has change, I am now considering the IQ-900... just wondering if I could eventually up-date the software of the 900 to make it air intergrated?
JONATHAN K  I think the problem would be more of a hardware issue. I don’t believe that the IQ-900 has a receiver.
Catherine T  thank you Jonathan.... it would explain the price difference as well! Now I have to decide wether I give up on air integration... or keep on spoiling myself ;) but you gave me the answer I was looking for.
