there is this endless fascination we all have at one point or another with speed, and arrow speed in particular.
heck, it roped me in enuf to have owned at least 5 different chronographs over the decades.
but, truth be told, you draw and release an arrow and you will KNOW if it's fast enough for ya at the distances you need to fling it for your hunt. what will matter much more is the consistent accuracy you can muster to deliver that super sharp broadhead. critters don't care 'bout arrow speed, they can out run and out duck the fastest of arrows, too.
i sold off all those chronys, 'cept one that i still use for working up boom stick loads.
imho, there are much more important things to trad bowhunting than pure arrow speed, or even knowing how fast an arrow can fly out of a particular bow. the true test of any arrow speed is during the hunt, not under arrow speed testing conditions in the basement range. :D
