Have had the Kestrel 4000 for several years and provided accurate Readings in all modes of measurement. Although, recently it just stopped working, so I presume they only function for a given period. This one worked well for four to five years.

Without the Kestrel 4000 Pocket Wind Meter long range shooting pin-point accuracy at 1000-1500yds would be inconceivable. This instrument gives one the necessary crosswind, humidy, ect. information that one needs to feed into their ballistic program to be completely successful. It is the best made one there is!
