Ross Oliver asks:

Does anyone, particularly in the SF Bay area, have experience with
this
brand of compass?

I'm not in the SF area, but I've got a SIRS compass in my homebuilt.

What is involved in swapping out the ccompass compared
to repairing?

Take out four screws, swap compass, put in four screws. Should take
about 10 minutes. If it's electrically lit, you'll have to do a two
wire connection - maybe another 10-15 minutes.

....Yes, swapping will be more expensive, but to me it would
be worthwhile if the SIRS compass really does perform better.

I had a vertical card compass prior to the SIRS. Didn't like the
position I had it in, and didn't like how it operated. It was a bit
sticky, and needed to be adjusted every 6 months or so. I put the SIRS
compass in and love it. Very accurate, doesn't need adjusting (at ALL,
yet, after about a year), and easy to read.

I definitely recommend it.
