1004 yards is 918 meters so I would say one of your devices is set for meters and one for yardsI have the Kestrel/Hornady 4 DOF and today I noticed for the first time that when I enter the target yardage in the calculator (1,004 yds), the single target engagement screen in my cell phone app shows Rng 1,098. Conversely, when I enter 1,004 yds in the single target engagement screen the calculator changes to 918 yds. Would appreciate any advice. Thanks.
