Product Description

The G2 literally flips conventional Chronograph technology upside down. By inverting the system the G2 is capable of measuring in adverse light conditions making the measurements more accurate than conventional chronographs, even indoors. The light sensors were spaced 18” apart for more accuracy and the sunscreens have self-contained LED lights when a little extra light is needed. Collapsible and compact, the system is quick and easily deployed from its heavy duty storage case. Higher accuracy was achieved by using a high speed 48 MHz processor and by designing a circuit with an advanced data interface that allows each unit to be computer calibrated at the factory after assembly. The end result is the ability to provide much better accuracy than other chronographs on the market (+/- .25%) and measures from 5 to 9,999 FPS.

  • 18” sensor spacing for maximum accuracy
  • Each unit factory calibrated to within +/- 0.25% accuracy
  • Built in LED Light Kit
  • Bluetooth to interface with Smartphone
  • Rechargeable Lithium Ion Battery
  • Ideal for Firearms, Archery, Airgun or Paintball
  • Meters Per Second (MPS) or Feet Per Second (FPS) readings
  • App displays velocity, logs data, notes, weather conditions and easily exports via SMS or Email

• Carry bag included
• Heavy Duty height adjustable from 15” – 42” Tripod
• Includes 1/4-20 dovetail plate to attach to the chronograph for quick assembly


A free App is available for download that displays the velocity of each shot on the phone screen and records it with other data identifying the load and environmental conditions. The App also automatically calculates Average Velocity, Standard Deviation, Min, Max and Velocity Spread for the shot string. The data is stored and can be exported via Email or simply recalled for reference at a later date.

    The chronograph itself (and the smartphone app) are “5 star”- simple to set up and connect, and error-free in operation. The supplied tripod is the only negative (the one I got was quite different from the one pictured). The tripod is a bit too lightweight considering the weight distribution and size of the chronograph, and the quick-release plate connection is rather loose and wobbly. The only change in the app I’d like to see would be the addition of average Power Factor for a string.

    Purchased the G2 from Midway (great price from them) when I received it I read the instructions (believe it or not). Plugged the unit into the charger, checked it in a few hours it was ready to go. So I wanted to test it I mean really test it! I assembled the unit as it was then dark I set up a heavy cardboard box in my basement, and got out my old very basic lever action BB Gun. Shot about 6 bb’s through the unit. It picked every shot, you gota know if it picked a bb it will work for bullet. The only problem I had was the on-line software will not work with my old android tablet. It works great with my S6 cell phone. Time for a new Tablet!

    So far so good. I just unpacked and it looks good. I plugged in the charger and turned on the unit. I opened the app on my phone once I turned on the Bluetooth and entered the location data it pair fine to the phone and seemed to work fine. I will range test in a few days and see what happens.

    Does anyone have a fix for a more stable tripod? My unit won’t sit straight and the whole thing wobbles like crazy. I won’t shoot through it until I can fix the platform. At present it would probably blow over in a 5 mph wind since it won’t sit straight inside my house

      The tripod has a hook on the underside in the center that is for hanging a weight to help stabilize and lower the center of gravity. The adapter on top that allows you to angle and pivot the chrono need to be made sure that it is tightened down. Sometimes when it is swiveled it can become loos which is where you get a lot of that wobble.

    I received my Chrono yesterday and took it to the range today. I am a competitive airgun shooter and need accurate data to better tune my airgun to different pellet weights. Some of my first observations were that the head on the tripod that holds a rather large screen and chrono assembly is inadequate and hard to adjust. The app for capturing your shot string data in not that easy to understand and the instructions for use supplied with the chrono don’t explain much. I called a Caldwell representative when I returned from shooting and he was very helpful and got me on the right track to using the app. A few more sentences in the instructions would have
    eliminated the need for that call. That’s the reason I only gave it 4 stars. The unit was easy to assemble and set up, packs nicely in a heavy duty case. It recorded the shot string nicely and I had no error messages. Now that I know how to from the first page to the second page, where calculations are made, it is going to be much more useful to me. I know there are more things the app can do, that would be helpful, but I don’t know where I can find the information.

    iOS app isn’t available in New Zealand so I’m unable to take advantage of the bluetooth features. Please release an update to fix this issue!

      For a short time our apps were taken off the store and needed to be renewed. This was taken care of and they should all be back up.
