I hope you've discovered the benefit of your new Electronic Conspicuity device when interfaced with SkyDemon?
It's like having an extra pair of eyes in the cockpit, even if they are on your knee/dashboard.
Don't fixate on your SkyDemon screen, but give it a quick glance on your instrument scan every 10 seconds, or so.
An icon indicates the position of other aircraft relative to you. The colour changes from No Threat, to Have You Spotted It Yet, to DECONFLICT AND MAKE IT SNAPPY!
Adjacent to each icon is a number indicating their height relative to you. + means they're above; - means they're below you. 0.1 indicates a height difference of only 100'; 1.2, and you have ROUGHLY 1200' of separation.
You've already RTFM'd (obviously!) so you already know this but one feature I missed is that you need to carefully coordinate the setup of your aircraft in SkyEcho and SkyDemon to avoid the dreaded RED SHADOW which may cause you to take avoiding action when none is required.
SkyEcho doesn't allow you to enter a hyphen in your call-sign, SkyDemon does. Check your SkyDemon now - Edit Aircraft and take the hyphen out if, like me, you were originally hyphenated.
Further down on that screen, also check you've entered your transponder's Hex Code. And make sure it tallies with your SkyEcho setup.
Any discrepancy between -Echo and -Demon and you may find you've picked-up a tail you can't shake. Like when you're riding your bike down the motorway and find a police bike in your mirror blind spot.
On the upside, uAvionix Support are brilliant and quickly resolved the issue with a phone call.
