Hi Frank,
Why do you think the SN10's wind calcs are that much more (if any)
superior than the 302's? I've never seen anything empirical comparing
them. I don't think I've ever read anything even written that was
hear-say. I have seen a 302 in action and it's wind calcs seem pretty
good to me. You also can't beat the size; good vario, certified logger
and GPS all in one nice, small package.

However, the suggestion made to split the volkslogger from the sn10 and
thus have a backup system does have merit. As I said at Fairfield, the
SN10 can also now drive a PDA passing the GPS data through and adding
other info to it.

Just my 2 cents

Hi,

I have been using a SN-10B/Volkslogger combination in my LS-4 for the
last 5 years and have loved it. However, I just acquired a glider with
a CAI-302/PDA combination and am contemplating swapping the systems
before selling my LS-4.

I like the presumed flexibiity of taking the PDA with me at the end of
the day, having the flight log on the SD card as opposed to having to
upload to a laptop, and having the option of running different flight
software on the PDA. I also like the idea of having it with me at the
pilot's meeting and being able to set up the task and/or do what-ifs
for AATs without having to be at the glider.

However, I'm not sure about giving up the SN-10's simplicity and its
superior (I think) wind calculations.

At the risk of starting a religious war, I would like input on the
strengths/weaknesses of the CAI-302/PDA (running GPS Glide Navigator II
or similar) for competition use as compared to the SN-10, especially
from those of you who have used both for competitions.

TIA,

Frank
