Review:
I do not have any direct experience with the Oehler devices mentioned by others but will compare with the ProChrono that I have been using. The optical-type chronographs have some limitations that most everyone is aware of but they are relatively inexpensive and get the job done; albeit with some quirks and frustrations.
The Garmin’s setup is very simple. Once synchronized with the Shotview app, the device updated in a matter of minutes.
As you can see from my earlier pictures, it comes with a small tripod that works well, but it also functions off of a table top. It also can be mounted to a traditional camera tripod and adjusted to shoot standing.
When preparing to shoot, you simply input your bullets weight on the device when you begin a session. Controls are simple. 4 buttons.
Once you input the bullet weight, the screen has a graphic that reminds you to shoot between 5”-15” inches above the unit. I stayed 5”-6”. It also captures from the side. I did not test how far it would work from the unit, but it is doplar radar, so extreme angles will induce a cosine error.
The unit takes about 2-seconds to process between shots.
Once you close the session, the data transfers to the app. You can rename and add notes then.

Here is a sample of its export file:
With my old device, I was able to set up my strings on the app before I went to the range. With this you have to label everything on the back end.
In regards to the earlier battery question, it is Lithium ion and is not user serviceable. I ran it about 45 minutes and the battery indicator still showed full.
The unit does not indicate any IP rating, nor is it mentioned in the manual but there is a weather guard over the charging port. I would not use it in a downpour.
If you only have access to an indoor range, this would work very well, especially if you cannot set up in front of the shooting station. Just be sure that the unit is behind your muzzle blast. Would also excel for PF testing at matches. Very quick, very easy and would work under a canopy or shelter. Not sure if USPSA regulates the device used.
As far as accuracy, who knows. My FPS may not be the same as yours, but it is very consistent. Time will tell. It’s radar. It can only determine speed at a set point in space (or points). I doubt the radar is particularly powerful. It didn’t drain the battery.
In total, I like it. Simple, easy to set up and use.
