I may be old-fashioned, but I prefer the mechanical counters; much less
prone to error and highly reliable. They can be mounted atop a clip-board
(or are they extinct?), and one simply assigns one to each type of data.

Subject: [ECOLOG-L] Dual counter
Dear listers,
I'm looking for a manual counter (mechanic or electric) to count flowers
in
the field. Since we are studying monoecious plant, female and male flowers
need to be counted separately. It would be ideal to have a counter capable
of
counting two objects (e.g. use thumb to click button for male and index
finger
for female flowers).
We have bought this electronic dual pitch counter
(http://tallycounterstore.com/ps116_electronic_pitch_counter_1.html), but
you
have to press a button each time you switch between two objects (which is
very
inconvenience). Does anyone have any recommendations for a counter that
fit
our application purpose?
Thanks.
Jing
