Maybe Terry and I will expand this thread to include thoughts about hog lights as well as reflective wraps and lighted nocks.
In late-day hunting -- like deer at dusk -- being able to see the arrow in flight is important, but difficult. Making that easier is worthwhile.
If the arrow is not a pass thru, seeing the arrow as the deer runs off can really help.
Finding the arrow is always helpful.
But, you have to see what you are shooting at. For hogs after dark there are some ideas we can share.
