Ever need to know how fast your bow or weapon shoots? I have a Chronograph for sale. Only been shot two times as you can see. The system works however is missing out on the front diffuser. You can buy it or make one out of cardboard, that's what I did. Chrony will certainly take it as a trade in for a more recent model if you like the gadget and ever desire to upgrade.
The Chrony has 2 eyes (or image sensing units) found in each of the black plastic housings at the front and back of the main unit. They are located under the Twin Lenses at the bottom of these housings and they detect the passage of a bullet over them by picking up the modification in the amount of light. (They discover a momentary modification in light strength.).
