Zoop air mode vs nitrox mode at 21%

[Lizard Leg]

Just wondering if anyone has any experience diving the Zoop on air mode vs. nitrox mode at 21% - does it calculate everything the same?

I can't speak directly to the Zoop, but I believe all the Suunto computers work similarly . In EAN mode, my Mosquito (and all Suunto computers) rounds the %O2 up (to 22%) for its MOD calculations.

So by the formula MOD @EAN21 should be 187 ft, the Mosquito gives me 177 ft (equivalent to MOD for EAN22).

All of this is entirely theoretical since that is well below the recreational no decompression diving limits..

The Zoop is supposed to be identical to the older Gekko. If it is the it does round up 1% O2.
