To build bracket for mounting phone to bow: Bend two metal strips at right angles using a vice (heating metal not necessary). Tape industrial velcro on the inside bend. Tape velcro to back of phone and attach to bracket in the same position as a traditional bow sight. Drill holes in bracket to attach to bow (use a 3/16" titanium drill bit for hole, and a 5/16" bit to bevel the hole). I used #10-24x1" flat head phillips zinc bolts to accommodate my quiver bracket. Counter-sink hole before drilling, put some 3-in-one oil on metal strip, then drill very slowly to keep drill bit cool. File off sharp edges, paint with acrylics, and finish with rust-oleum protective enamel. Views of bracket are included in screen shot list

- Check local hunting regulations before hunting with electronics attached to bow
