Re: which crossbow for dad?
So many choices and levels of expense.
Recurve style usually louder, slower and wider making it a bit harder to maneuver. But they are simple to maintain and lighter up front. Compound style usually faster, narrower and quieter. But harder to maintain and heavier up front.
Cocking a crossbow is also a consideration. Most are cocked with rope cockers or a cocking device such as a crank. Crossbows with longer power strokes require more effort near the end of the stroke to fully cock them with rope cockers. Cocking devices such as Parker's Sidewinder and Ten Point's Accu Draw make cocking a breeze for anyone. If the effort to cock the crossbow is a concern, consider one that has a crank available, or if using a rope cocker, one with a shorter power stroke.
The Excalibur Axiom is a recurve style, lightweight, affordable and is bulletproof. Not available with a crank but does have a short power stroke making cocking relatively easy with the rope cocker.
The Parker Enforcer and Tornado are compound styles with great performance, quiet and compact. Heavier up front though. Parker's sidewinder cocking device will work for both as would a rope cocker.
Both Excal and Parker have great customer service.
If Dad is gonna be hunting from the ground and wants a super reliable, easy to maintain and cock bow, look at the Excalibur Axiom.
Alot to consider and good luck.
