Surefire E2D LED Defender Ultra is tough to beat on an Elk hunt. Surefire E1B Backup, should be in a pants pocket too. Have a 12-pack of those CR123A batteries, like $24 bucks, sprinkled around in backpacks and the truck and tent. Back in camp or in truck, Streamlight has a Microsteam USB for about $37 bucks, it's a 10 out of 10. Think in 50 years went from that 2-D cell angled red filter US military, could barely read a map by that thing, then progression of 7-D cell Maglites on down to their AAA models, to a few Streamlights, then onto to Surefire. All of these have been great flashlights for the work they did, and the battery costs are just a way of buying daylight when ya need a few extra hours of it. Good luck on your pick.
