New Garmin Xero C1 Radar Chronograph

[Rocketvapor]

The beam width of the LabRadar is listed as:
Beamwidth 7.6° x 18.5° (Transmit)
IF the horizontal is 7.6° then bullet path crossing into the beam at 15 inches offset will happen @ about 7 yards.
At 3 inches offset then the bullet path crossing into the radar beam will happen @ about 2 yards.
The real estate on the back side of the LabRadar could hold an antenna much larger than the Xero (2" X 3" ?) and likely have a smaller aperture. No info on beam width is available for the Xero.

Here is a really crude drawing of the XERO mounted 5" back from the muzzle/5" offset from bullet path, and 15" back from the muzzle/15" offset from the bullet path.
Not knowing the beam angle I included 30°, 15°, and 7.5°


A test turning the unit until it lost the bullet might help determine beam angle.
Velocity reported might even decrease as the unit is rotated (about the horizontal) as the bullet will intercept the beam further down range until it didn't detect the bullet crossing into the beam .

Alot of information gathered. What is to be learned from it? I'm over 70 years and often confused.

Thank you!

Mine said the same thing. I'm not buying a new phone just to run the app! Ha ha I do have a new Galaxy tablet for my Shot Marker so I'll download the app on it.

Thanks for the tip. I run my Long Range camera on an older Galaxy also. I can upgrade that for a lot less than a new phone.

Long story short: you have to turn it on, answer a question as to the velocity range you’re wanting to capture, press ok a couple times and set the Garmin down on the bench, pointed towards the target you’re shootin and begin firing. It just works. You can get all the basic information such as max/min, ES, SD, AVG etc with only the Garmin itself but you’ll have to write the info down in your old big chief notebook. The App allows you to store the data and make notes on each string as well as download to wherever.

One caveat to my simplistic directions is I was somehow mystically able to get my Labradar to work within its capacity as well.

LOL. I have a Garmin and know how it works!
I couldn't figure out what the point was for the detailed information and diagram.

My son and I have been talking about an upgrade.

Your 80 years young. Get a new phone, you'll be around long enough to get a few more down the road. Enjoy your Garmin.

Yes it’s called... Follow the directions.

I had asked a question about Garmins suggested placement(on bench).

 

[Rocketvapor]

About the crazy drawing
Knowing beam angle might help with placement position.
Garmin says 5" X 5" to 15" X 15".
Anything along this line would give the same angle between the bullet path and radar beam.
I watched a video where two units were tested with various positions between them.
From the results, like 5" back 20" to the side, it looks like beam width is at least 30 degrees, at least in the near field. The two units in the video compared quite well, even with 22LR.

Since the Xero gives a single velocity, probably up close within a few yards, with the bullet traveling just far enough to give a Doppler difference frequency of sufficient amplitude and duration for velocity resolution, it will likely be immune to adjacent shooters and cross fires. The LabRadar, seems to have the range to catch crossfires/adjacent shooters that enter it's beam or triggers the noise detector.

Just trying to understand how it works, and why it might not under some conditions.

 

[Krogen]

I think it would be interesting to place a Garmin on a bench adjacent to a shooter and attempt to learn a couple things:

1) With the Garmin pointed directly at the target, how far away from the shooter can it pick up a shot?

2) With the Garmin on the adjacent bench at a typical shooter separation, can the Garmin be angled toward the adjacent shooter's bullet path and pick up the bullet?

 

[Rocketvapor]

For off axis placement watch this video (not mine)

 

[nmkid]

A little mystified. I know, read the directions...I have. I guess I missed it. Say I finish shooting a group, then stop to get ready to fire another group. How do I end the first session and get the Xero ready for the next session?

 

[Rocketvapor]

From the screen that shows the velocity, press button 2, the Power/Return button.
Down button, End Session. Then OK button. New Session.

You can practice button pushing without firing a shot

 

[Old Navy]

Just got back from my first session. Easy to set up as advertised. Velocity and ES numbers were as expected but the SD on two groups was reading 2191 and 2211. What is the deal with that? One string was perfect. Is there and update for this? I haven't downloaded the app yet.

PS: I downloaded Garmin Express and did an update. I will try it again tomorrow. Now if one of you computer wizards can figure out how to download the sessions from the Xero right to the pc, that would be awesome.

 

[RCE1]

Only used with a .22 Cricket airgun, but it's not missed a beat. Made this mount out of scrap. Seems to work well.

 

[Rocketvapor]

@Old Navy
That is strange. Looks like you might want to contact Garmin for a replacement.
Maybe do a "Reset" and try again.

@RCE1
How much did that mount cost you?

My Xero will be here Mon. I tried to download ShotView and I got a message that my device is not compatible. I have a Samsung S8 with a 7.0 operating system. I Googled ShotView app. He says I need a 10 system. Is there a work around for this. I will be 80 in two weeks so please take it easy on me.

One thing I noticed is I couldn't down load the app until I had the device in hand and turned on. That was with an iPhone. Hopefully that might be your problem.

 

[RCE1]

The steel is just some scrap I had on hand. There is a SmallRig quick release that's hard to see that was 20$. I have a matching one on the OEM tripod, as well. Simple as it is, that tripod is really good.

Samsung S8 is not compatible because it is not running a full Android version but a variation of Android (Go edition). I have the same S8; will wait for new S24 to come out so I can buy the S23 discounted.

Just got my E-mail that mines in the mail just in time for post-turkey ballistics checks.
