The primary unit of measurement for spine is deflection in thousandths of an inch (a deflection of 500 equals 0.500 in or 12.7 mm) Deflection is sometimes converted to pounds of bow weight by dividing 26 by the deflection in inches. (26 in⋅lb divided by 0.500 in equals a spine of 52 lb) [23]
Lighted nocks, and other custom features for arrows associated with night bowfishing are commonly available. Line is attached to the arrow by tying to a hole in the arrow shaft or through the use of a slide system. Bowfishing line is often made from braided nylon, Dacron, or Spectra. Commonly used line weights range from 80 to 400 pound test ...
A type of arrow rest that has a prong or blade that supports the arrow for the entire draw cycle and shot. The prong or blade of a drop-away rest that supports the arrow when the bow is at full draw, and drops down as the arrow is released. let-off (measure) – The difference between a compound bow's holding weight and draw weight. Expressed ...
Modern compound bows are typically equipped with substantially stiffer arrows than an equivalent draw-length and draw-weight recurve bow would be. Another advantage of the center-shot riser is that the arrow need not bend around the riser (nearly as much or at all) during the shot. Fine-tuning may be accomplished by adjustment of the arrow rest ...

Traditional target arrow (top) and replica medieval arrow (bottom) Modern arrow with plastic fletchings and nock An arrow is a fin-stabilized projectile launched by a bow.A typical arrow usually consists of a long, stiff, straight shaft with a weighty (and usually sharp and pointed) arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and ...
A bowstring joins the two ends of the bow stave and launches the arrow. Desirable properties include light weight, strength, resistance to abrasion, and resistance to water. Mass has most effect at the center of the string; one gram (0.035 oz) of extra mass in the middle of the string slows the arrow about as much as 3.5 grams (0.12 oz) at the ...
Computer analysis by Mariusz Magier, Adrian Nowak and others published in 2017 found that heavy bodkin point arrows could penetrate typical plate armour of the time at 225 metres (738 ft). The depth of penetration would be slight at that range but would increase as the range closed or against armour lesser than the best quality available at the ...
