66681EDIT: Philip Engle-Kestrel 4000
- Jun 7, 2005Hello Philip.
Thanks for your interesting and articulate OR below. I borrowed a Kestrel
for a while from a friend, in one of its lesser incarnations. I've always
been tempted by the full version, as I found the smaller unit a toy, and of
limited utility. Your edits follow. Please incorporate, and upload an HTML
version to the OR test folder on BGT. Thanks very much!

I believe is the case), do you think that this omission affects the utility
of the instrument, as nighttime minimum tent temperatures are useful to
know, and it's a drag to have to wake up to take them?

bounds of what the review should state into speculation about Kestrel's
marketing. I don't think these two sentences add anything to the review.
Please omit or add something that better analyzes your feeling that you may
not be the intended consumer. Why should that be? Does effective use of the
data collected demand a higher level of analysis than the average
backpacker possesses? Does this limit its utility seriously, do you think?
You rather hint at this in the discussion of the lack of interpretive data
and I'd like to see this expanded upon.
Incidentally, have you used this in conjunction with the Sierra Club's
useful text on regional meteorology of a few years ago? This covers
prevailing whether patterns in the Whites, for example. If I can dig it out
I'll send you some info.
