About This Calculator |
| This calculator is pre-loaded with Bunjie, Jr.’s specs so you can see how your crossbow compares!
Find out how efficient your crossbow is (or any crossbow) by entering accurate data to get a pretty good estimate. Crossbow efficiency isn't talked about very much, but it's quite important. This is a measurement of how much energy your crossbow stores when it is cocked, and how much it delivers to your arrow when you pull the trigger. The higher the percentage of efficiency, the better—more efficiency means more energy imparted on the arrow, and less energy left over. Leftover energy is wasted, dumped into the limbs and riser and scope, and creates sound and heat. More leftover energy means more potential damages to strings, limbs, and other parts.
