Re: Crossbow engineering question
The compounds do utilize the same technology with less hold weight to a degree than peak draw weight. The recurve styles hold thier full wieght at the trigger latch.
With that said, crossbow triggers still hold tremendous forces at the latch so trigger pulls all on the heavy side. Several manufacturers are adrressing your suggestions though with redesigned triggers that allow much lighter pulls.
I think this will be a direction we see crossbows go as trigger designs improve. It is a heck of a liability though with crossbows. There is alot of force stored in the limbs. Not only is the user concerned with where the weapon is pointed, but that all fingers and appendages are clear of the rail at all times.
Bowtech went with a new trigger design that did not hold the entire weight of the limbs. They had to recall it soon out of the gate. Winchester tried as well but had to redesign the trigger which resulted in the pull being heavier.
As far a letoff is concerned. Compound crossbows have it but I suspect that not on the same level as compounds becuase the power strokes are half of a typical compound. 80% let off cams may not produce enough force in such a short stoke to generate the desired speed.
I support all hunters, regardless of weapon or technique!
