Ken,

How are you liking that 100' difference in altitude between the Aspen and the round gauge?  That's the most annoying thing for me with my Aspen, but the benefits more than make up for it...

Looks great, Ken.

Very nice, Ken.....please continue to spend a little time looking outside ;-)

I haven't flown with the new setup that much yet*. What's the cause of the differential if both are set to the same pressure ?

* I found a broken oil cooler mount this weekend so I'm grounded until I can arrange to get that fixed.

I wish a had a good answer, but I chalk it up to simply having 2 different instruments measuring the same quantity.  I saw the install myself, both instruments are tied into the exact same static line.

I figure the Aspen has a pressure transducer, while the round gauge uses antiquated aneroid wafers, so I typically side with the Aspen.

My usual altimeter setting procedure is to set the baro on the Aspen, and then move the hands on the round gauge to match the Aspen.

Anyone else with an Aspen experience this?

Thanks for the pilot report.  I'll be that much further ahead when I get mine installed next year.

My Aspen and my altimiter are in agreement most of the way up to 10k. A quick peek at your altimiter calibration records on the old gauges will show you how awful those things are for accuracy though!
