The V3 Chronograph attaches to a weapon’s muzzle like a bayonet, and provides bullet velocity data as well as other information useful for improving accuracy. The V3 Chronograph features several upgrades over its predecessor, the V2. These improvements include a thinner sensor deck for optimized performance and an anodized aluminum frame under the V-Block makes the sensor stronger and provides possible alternative mounting positions. The V3 bayonet sensor also features a second data connection point that faces downward for easier mounting on weapons with shorter barrels and longer handguards, and a metal cam buckle makes strap adjustment and release fast and straightforward. The V3 Chronograph also utilizes an upgraded display, featuring a smaller, balanced design that sits at a comfortable angle. The display also sports an easy to use 3-button interface, can receive updates via micro SD card, and can run on either a single 9-volt battery or two CR123 batteries. In addition to projectile speed, the V3 Chronograph provides your Standard Deviation, and has modes optimized for shotguns, air guns, and rapid-fire mode that provides your average rounds per minute. It comes as a kit that includes:

  • Display unit
  • Retractable connection cable
  • 6’ connection cable
  • Stainless steel blast shield
  • Thick and thin rubber V-Block spacers
  • MicroSD card with adapter

I like it. I don't love it. You can't get hand guns with it. It is sometimes hard if not impossible to get your rifles with long hand rails and picatinny slots for bipods out at the end. ALSO.... with a radar chronograph, you can use the shots you are zeroing with to get your speed. With this chronograph attached to the end of your rifle.. your impacts will shift. Mine shifted about an inch at 100 yards. This means you have to waste precious ammunition instead of killing two birds with one stone using a radar chronograph. Just some things to think about. If i could do it all over again, i'd get the radar chronograph. You save money in the long run and it's WAY more convenient. Not sure why EuroOptic doesn't offer them.
