Bow Hunting Whitetails With Garmin Xero Bow Sight

[@spkt0r]

Questions: 1.How long does the battery last for? 2. What are its operating temperatures? 3. How tough is it? 4. How much weight does it add to the bow? I also had no idea that Americana Outdoors worked for Garmin, this was the longest commercial I have ever seen. A commercial within a commercial, it's inception.
