Umm simple, its called shooting an azimuth with a compass and a distance with a rangefinder or guess (error on the long side).
Buy a military compass, learn how to shoot an azimuth. Go to a known measured distance track, i.e. local high-school track. Start walking and every time your left foot hits the ground count it. Do that several times to get a flat ground average pace count. Once that's established do it on hill ground. Your strides will be shorter so your pace count will be more than level ground. RECORD THESE NUMBERS!! This is your personal pace count.
I learned this skill many years ago as a private in bootcamp at Infantryschool at Ft. Benning. Most infantry soldiers has their pace count written down inside our patrol cap. We also have Ranger beads to aid in long distance navigation. Those basic skills as an infantryman has came into play all over the world my entire life since, from navigation in theatr, in state parks, to finding my car in a new city!
Night hunting is simple with a lazer, simple have it slaved to your scope zero and walk strait to your dead coyote.
