Using a Timex alti watch in my Windsong it recorded 3700' AGL as the highest
attained.

On a somewhat related note, I know some individuals have used a series of
variying width white stripes on the lower surface of the wing as a means of
estimating altitude. Obviously this method does not work for very high
altitudes when the aircraft is at the very limits of one's vision.
For us
. Does anyone have a
reference, guide or link to information how one might go about utilizing
these stripes as an aid? Specifically I am looking for suggested widths
and
placement of the stripes.
On another related note, most hunting scopes (for rifles) have graduated
lines on the cross
The July 1998 issue of RC Soaring Digest described a
pattern of chordwise stripes of varying widths (6 to 1/2)
which can be used to estimate altitude.
We'll make the article available as a downloadable PDF on
the RCSD web site, hopefully tomorrow, Thursday. RCSE

Take a look at the Zlog. http://www.hexpertsystems.com/zlog/index.html It

A good source for the Suunto altimeter watch is http://www.rei.com/outlet. Keep your eye out at this site because they often go on sale at the end of the seasons (summer/winter). I picked up mine for about $120'n change... ;^)Blue skies, Doug

If money is no object and you want to keep track of your max altitudes without the need of a laptop, one can go to Paragear and get some very ruggedequipment. Check eBay also for the same things. These units are tough and take a LOT of abuse - mine is constantly getting dropped and knocked around

The highest that I've verified was around 1850 m if I remember correctly, a
couple of years ago with a Picolario. I used to put my Casio altimeter watch
in my XC, and it had a max altitude, along with max rate of climb and summation
of altitude gained.The highest I recorded with the watch

There are 2 types of temperature dependance with respect to electronic
