Finally my new chrono arrived. I always wanted to make a comparison between the two instruments and see how they fare.
In review will be an xcortech shooting chrony and and F1 shooting chrony.
Here, both instruments out of their boxes. Left is the excortech shooting chrono ready for use. The green box is the F1 chrony and its attachements.
Here's the F1 chrony unfolded and attachments assembled and ready for shooting. (don't forget to buy 9V batteries)
The aim of this test is to determine what is the speed difference read by the test equipment. To be able to achieve this both instruments was used to measure each shot made from the test gun at the same time. Both the chrono was aligned so that the shot made from the gun passes though its sensors as the pellet exits from the barrel.
The AG used is a Spitfire 1000 in .177 caliber. Pellets were weighed to make sure they are of the same weight. Just a note, This AG is designed for 10M target competitions we initially chronoed it at 350 FPS on the Xcortech. We made some modifications on the internals to see how it performs on higher power output. (A separate post on this in another thread)
Here's the pic of the test setup.
Another pic showing the target stop at 11 meters.
Below are the shot strings made with one single charge of CO2 from the pygmy tank.

Feature | XCORTECH | F1 CHRONY |
SIZE | Compact | Folding Design |
WEIGHT | Very Light Made mostly of ABS plastic | Slightly Heavy due to the Metal folding case |
SETUP & USAGE | Can be used right out of the box, just switch on. | Requires a bit of assembly. |
FUNCTIONS | Measures projectile speed in Feet and Meters per second. Rate of fire. Joules. | This model measures projectile speed in feet per second. Additional data is available if a remote controller or data printer accessory is added. |
PROS | Ease of use, Multiple data results. Has its own light source. Popularly used among Airsoft enthusiast | Industry standard in measuring bullet/projectile speed. Wide sensor area, can be used in testing different projectiles |
CONS | Small sensor area, muzzle must be very near the pass through hole to make measurements | Only measures speed of projectile in FPS (or MPS) format. Needs ample light to be able to take measurements or use an accessory light source. |
