I have the pro chrono and like it a lot. I have a setup like the one in the picture and it comes in handy for adjusting the height when shooting up close or when putting next to the target to get "down range" speeds.

ProChrono Digital Chronograph

Measure the velocities for your rifle/pistol bullets, arrows, shotguns and pellet guns - at a price anyone can afford. ProChrono Plus features an expanded shooting area that's nearly two times the size of comparably priced models. Measures velocities from 56 to 9,999 feet per second and runs on a single 9-volt battery. Shoot in all weather since this chronograph operates in temperatures as low as 32° and as high as 100° Fahrenheit. Has all of the features you'd expect in a chronograph costing much more. Allows you to review 50 shots with power-down memory (review at home), high and low velocity settings, standard deviation, number of shots, average velocity, deletes current velocity and even has a printer interface so you can hook it to a printer to get a hard copy of the data. Shows metric or FPS scales and features durable plastic diffusers.
