Nerf Blaster - FPS Chronograph Speed Tests!

In the spirit of popular TV series like Myth Busters and The Deadliest Warrior, here is the Nerf blaster version of FPS Speed Tests! :)

I've managed to get a Shooting Chrony F-1 FPS Measuring Chronograph, so its now possible to generate some reference FPS data for stock and modified Nerf blasters.

You can spot the same device being used in the above mentioned TV series to measure projectile speeds for data comparisons. It can measure speeds from bullets, arrows, pellets, paintballs... and yes, foam darts too. From 30 FPS (feet per second) to 7,000 FPS.

As a projectile passes over the 1st sensor, it starts a counter and when the projectile passes over the 2nd sensor it stops the counter, the device calculates the FPS in realtime and the results pop up on its LCD screen.

FPS measurement is of keen interest to Nerf enthusiasts and especially modders who can finally get some quantitative data on the actual speed of the foam darts fired from modified blasters (instead of saying "its faster" just by looking).

Here is a quick review of the Shooting Chrony F-1 that will be used for these FPS speed tests:

Shooting Chrony F-1 (Box)

Shooting Chrony F-1 (Un-Boxed)

Shooting Chrony F-1 (Assembled with Light Diffusers)

Shooting Chrony F-1 (Mounted on Camera Tripod)

The device is designed to be portable (it folds up into the size of a brick).

Okay, lets start measuring FPS speeds!

Here are a few sets of reference FPS data that i've generated from some of my blasters.

Test Perimeters:
- FPS data are an average of 12 recorded shots from each blaster.
- All test shots are fired with the blaster barrel muzzle approx. 6 inches from the 1st sensor.
- Tests are done indoors with natural light sources.
- Foam darts used are Converted SDL Darts (CSD).

  1. How much are they and where did you get yours? I live in the U.S. and I would like to get to measureing the velocity of my darts. Please respond and your blog is exellent at detailing the key points of the blasters.

    1. OREO8349,

      I got mine from Amazon, around USD$80-$90... had to pay extra for international shipping to Singapore though (where i live).

      Just do a search for "Shooting Chrony" on Amazon and find the best deals. Since you are in the States, it should be much cheaper to get it shipped to you direct from Amazon. :)

  2. SG Nerf,

    can you do a shooting test on the stampede?

    1. Anonymous,

      Stock Stampedes clock in at around 45-55 FPS, similar to most stock Nerf blasters.

      I'll probably run a new set of FPS measurements on the newer generation blasters soon (along with their modded variants). Stay tuned for it. :)
