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
