Highlander - Vertical Card Compass

[Chief]

During my the build of my Highlander I developed an equipment list. I have always liked a vertical card compass so I installed one atop the pannel, even though I had serious doubts about how effective it would be, considering all the metal surrounding it. Recently I did an eight point heading check on the compass, using the indicated heading on the FlightDeck-180 and the Garmin 795 as comparisons. The vertical card compass was right on the money. There was no adjustment necessary. I realize I probably got lucky.

I put one in the exact same location and could never get more than two directions accurate. Finally gave up and sold it.
