garmin xero c1 chrono speed

[bahabill]

I am curious, does the C1 chrono actually read the muzzle velocity or is it reading the impact velocity. Asking cause all of my load development is at 100 yards being the longest they have at my range. But i seen a guy using his lab radar at 50 yards and said it reads impact velocity! the funny part was he couldnt read anything cause he was suppressed and it didnt work but I moved my c1 over and worked perfectly. He was going to store to buy one right after LOL.
but left me questioning the C1. is it actual bullet leaving muzzle speed or the speed it impacts the target. Getting new rifle ready for hunt and running out of time to fully experiment with. Thanks

The reading you get on the Garmin is muzzle velocity.

Neither unless you are impacting at 30 ish yards. The only way to read muzzle velocity is when we imbed sensors in the barrel. Otherwise, even the Magnetospeed doesn't read actual muzzle velocity.

What you do get is a computed muzzle velocity using a fairly common method. The same thing the Lab Radar and some others do. Most light screen devices do not back calculate, but instead just give you velocity at that devices location. Note this is Most not All.

This! You can use MV to calculate impact velocity.
