Generally, crossbow has 9 specs you should take into consideration
There are two main types of crossbows: the recurve crossbow and the compound crossbow.
The speed, or velocity, measurement of a crossbow refers to the rate at which an arrow is fired from the bow in feet per second (fps). Speed is the byproduct of a few factors including the crossbow’s draw weight, power stroke, and the weight of the arrow.
Draw weight is the highest amount of weight in pounds (lbs.) pulled when the crossbow is drawn. Draw weight corresponds directly with draw length, or how far back you will need to draw the string to fire the arrow.
Kinetic energy measures the amount of energy, or force, the arrow carries in the air upon being fired in foot pounds (ft.-lbs.). An arrow carrying high kinetic energy will strike an animal with more force and with deeper penetration, so it is especially important for hunters to consider this specification when purchasing a bow.
5. Power Stroke
Power stroke is also referred to as draw length and measures the distance of the string from rest position to fully drawn posture
. Like mentioned above, power stoke corresponds with draw weight and a crossbow with a longer power stroke typically requires a higher draw weight to bring the string to firing position.
6. Mass weight
The overall mass weight measured in pounds gauges the heaviness of the crossbow. Just like a rifle or regular bow, a heavier crossbow will be more difficult to carry long distances and harder to keep aimed on target when an arrow is drawn.
A crossbow’s length is the distance (in inches) from the end of the stock to the furthest end of the crossbow, which could be the stirrup or the dissipater pads on the limbs; this is not an industry standard. A longer crossbow also normally makes for a heavier crossbow. For this reason, taller and more robust shooters may be comfortable with a longer crossbow, while shorter, younger, and female users may prefer shorter models.
The width (in inches) measures the distance from end to end of the crossbow’s limbs when at rest. Just like with length, consider the width of different crossbows in proportion to your body. A wider crossbow may offset the balance of a shorter shooter, while a more compact model could constrain and be less comfortable for a more robust shooter.
9. Trigger Pull
Trigger pull refers to the amount of weight needed to pull the trigger in order to fire the crossbow. This is not an issue most shooters with dexterous fingers, but the average crossbow will have a trigger pull somewhere between 3 and 4 lbs.(3.5 lbs is the best), which is considered a safe and effective level.
