Pocket sized chronograph that comes supplied in a neat semi-hardshell case lined out w/ soft, anti-scratch material.The shell casing is manufactured from a padded material that will absorb some of the shock if this casing w/ the chronograph inside were to fall/drop.

The box opens / closes by means of a zipper rail that extends around three of the four sides of the pistol case circumference, whereafter the case folds open like a book, with the interior splitting into equal halves. The halves of the pistol case measures about 22mm deep, with a flat dimension spanning 145 x 80mm. The interior netting spans the whole width of both interior sides of the casing, running slightly over half way along the long sides. The casing's interior and exterior is completely black and the zipper runs reasonly smooth.

Included on the one side, you'll find the chronograph module and on the otherwise, your instruction manual. This you can always remove and replace w/ spare batteries and a charger for them if so desired.

The chronograph module itself measures about 140 (L) x 70 (W) x 26 (H), weighing in 174 grams.

It has silicone ferrules at the base, as well as the lid for the 18650 battery compartment. We recommend using a higher quality 18650 battery w/ consistent discharge and overdischarge protection, to ensure the longevity of your chronograph. To this end, please see this NITECORE 3.6v 18650 BATTERY, which will provide you with longer lasting performance on your chronograph, also longer usability on your battery as well as your chronograph.

The module weighs in 174 grams, has an old-school alphanumeric digital four-character display screen in front that light up red.

It features two rows of 8 infrared LEDs that detects motion sweeping overhead and you'll need to shoot over both rows, with a height clearance not above 500mm's and you'll need to make sure that there is no source of illumination directly overhead of this chronograph, even indoor fluourescent tube light, which makes it go haywire.

Also, as an interesting function, it can calculate kinetic energy and display such, after you put your projectile's weight in.

Then finally, you can set your velocity readings to be displayed in two metric settings and one imperial, though for practical purposes, it would probably be for the best to keep to FPS for speed and grainage likewise for weight.

At the base of this chronograph module, you'll have tripod threading, so you can easily mount this onto a (table) tripod of your choice. Just use a spirit level to make sure your chronograph is plumb before you start shooting.

The android software / app for this chronograph is outdated, so it is recommended to run an android emulator on your phone / laptop / desktop and use a USB to bluetooth adapter, if you'd like to use the app. It also seeems unlikely that the developer will be creating a newer version of the app, however, the QR codes for downloading the relevant apps can be found in the pictures, for ANDROID and APPLE respectively.
