I would not be real quick to seek further technological advancement to remedy the situation.
I would always rather hit lower than higher especially when I was the one having to do any tracking necessary.
An old wise bowhunter always told me, "Never shoot at a deer that is standing perfectly still and fully alert"!
"Shoot them when they are relaxed and walking slowly with their front leg which is facing you is forward."
"That is because a deer will naturally flex it's muscles and lower its body to make the quick jump to escape."
"A heart shot is a heart shot if the deer doesn't react, and if the deer does react then you still will have a good double lung shot."
This was in the day of us hunting with recurves, and I have a hard time seeing that a deer can actually "duck" an arrow from a modern compound bow.
These days, I think everyone watches the "pros" stop a buck just prior to the shot with a "baaaaat" and thinks that is the best thing to do in every situation.
Obviously, they don't show you the footage of the 5.5 year old buck that whips around at the sound and is a mile away before they know what has happened.
It is my opinion that a deer that lowers it's body enough for a complete missed shot was reacting prior to the shot, something other than the noise of the released arrow.
Something that isn't discussed enough among bowhunters is a deer's body language and when to draw, how to focus, when to release, and why.
And to be honest, talk sometimes isn't good enough. The school of hard knocks, bad luck, and experience is often the best teacher.
And when you think you have completed all your homework and have it all figured out,.... a bad shot, a flaw in judgement, etc... will bring you back to earth...and that is where we all need to be.
