IronGoober | FX Chronograph testing - Sling velocities 65 m/s (146 mph) @IronGoober | Uploaded 2 years ago | Updated 1 hour ago
I use a 34" sling (2mm UHMWPE, aka dyneema and leather) and 50-60g stones (weighed).
After the first throw, I thought I heard (187)...but it said 137. So that gives me more confidence this thing is correct.
Also, I ranged it, it's 250-260 m across the lake and a 22m drop (elevation loss).
Update: A side by side comparision with the Pocket Radar showed that they were within 2 mph of each other with a thrown tennis ball (~60mph) and within about 3mph when I was slinging a tennis ball over the top of them (~105 mph). I'm satisfied this radar is accurate within 1 m/s.
