Right on. Thank you for the input. I bought a Cobra w/SK-7 attached. The console actually keeps the SK-7 level while your reading the Cobra which is nice. I hear you on attaching an extra SPG. Suunto consoles do allow you to do this if you want. After studying the manual and the recommended safety steps to take if the Cobra fails, an extra SPG would be the key to maximizing safety stop time before surfacing (deeper dives). And a wrist watch would help complete covering the other bases. I have to admit I really like playing around with electronics so I am having fun with this before I am even taking it down for a dive. Very easy to use actually. I am still waiting for the PC software.
