I am going to build a new panel for my glider this winter and would
like to go with all small instruments.

The Altimeter is the only one that I am having trouble deciding on, I
thought I was going to need a "certified" altimeter but recently spoke
to a very reputable source and found out that a "certified" altimeter
is not required for VFR flying, so this opens my options.

I have it narrowed down to four choices listed below.


1) New Winter altimeter $900 ( A lot more than I would like to spend)

2) Used Aerosonic for $500 to $700 ( looks like a very nice
instrument, a bit heavier than the Winter)

3) UMA single pointer 20k $300 (These look very difficult to read
accuratly as the 20k is one full rotation)

4) Microtim digital altimeter from ( http://www.microtim.com/index.htm
) (This option looks very good to me, it takes up very little panel
space, easy to read, self contained long lasting battery, easy on the
wallet compared to other options)


I found a post by Mike Borgelt where he stated he was using a Microtim
altimeter and he reccomended it.

Does anyone know of any good reason not to install a Microtim?

Thanks for any advice,
Joe Simmers
