I used to hunt alone, day or night when i was in east tx with plenty of public land available. I make sure to have my astro, a back up gps, a compass in case the electronics crap out, a headlamp, a back up light source and extra batteries for all ele powered devices, and extra water. All that is day or night hunting, plus i packed a .45 with 2 additional mags. The following link is my next purchase for an emergency to carry on my person no matter where i go.

iv got a strobe beacon with an ir cover that iv started toting but the plb is my nxt purchase, and then a backup handheld vhf multi band radio.
I could be wrong but I thought in Texas you weren't alowed to hunt hogs with dogs on public land.
