I agree with Tim Taylor comments. I'm a long time user of the CAI 302.



I've heard some complaints that the software in the 302 was never updated..

Well I've never had a 302 Lock up, change settings all by itself, or switch to bluetooth because the lunar pull.

The 302 worked great form the get go and still does, IMHO



I think Richard from Craggy may have been getting false thermal indications because the TE setting in his CAI 302 was off for his particular glider.

The TE is easily adjustable.

BUT to do this and check it in flight you have to get the 302 to switch to CLIMB mode while cruising; this requires a switch installed, as the 302 automatically switches from Climb mode to cruise mode in straight flight.

You connect a simple switch to a couple of pins and you force the 302 to stay in climb mode, do some high speed zooms in calm air and you can see the TE compensation and then easily adjust it in flight.



Mike Borgelt and others have written quite a bit on what your looking for as far a TE compensation in your instruments and how to check them. This stuff is well worth reading if your not sure exactly how TE works and how it should be interfacing with your vario.





The 302 also has a option of pure electronic TE; you do not need a probe.. I used this setting on my Twin Astir and it worked super good.

Nick,

The CAI worked fine in the climb mode. The Cruise mode in my opinion it was showing false thermals.
