Garmin Xero C1 Pro chronograph

I have seen behavior like this or assumed that’s what happened when the Garmin missed a couple shots when I had it rifle mounted.
Are the errors recoil related, or from you mounting the rifle? I ask because I feel the Garmin is finally a solution to me getting chrono data for my 50 without mounting my Rube Goldberg Magneto Speed rig to what is already a monster of a rifle . The 34" barrel makes me think I will have to rifle mount the C1 to get it closer to the bore not to mention the, shall I say generous tank sized muzzle brake.

I refused to buy a LR but have a MS, and a Bulletseeker/SpeedTracker getting repeatable data from that one rifle has been a PIA.

With the C1, you only need to be within 5” or so of the bore line and within 15” of the muzzle. It does not need to be mounted on the rifle to get an accurate reading.

Getting on the rifle and adjusting can definitely trigger it. I think when I have a bad position and let recoil do what it wants I have also dropped several.
 
@huang I own a primos trigger stick tripod (that I used to use before my RRS came along). Found that it is perfect for mounting the Garmin out by the muzzle.

For example, I use it if the bench I am on is too short or too narrow.

Might be an option. Super fast to set up.

You mean with it mounted on the rifle?
Yes, sorry. I specifically meant when rifle-mounted I have observed increased dropped shots, likely due to wiggling/repositioning and/or lack of recoil control. It’s maybe dropped one shot ever when placed on the ground or bench next to the gun per the specified distances.

I've only ever used my Xero mounted on the rifle and I think it's missed maybe ~3 shots over the something like ~400? rounds I've shot over it. Being able to mount it to the rifle is what pushed me over the edge to buy one honestly.

What's better than data collected by the latest cool chrono? Data collected with the chrono placed in the same spot and chrono-to-muzzle relationship for every single shot, that's what. Plus, I can run it when practicing on props/obstacles (which is what most of my practice consists of these days) and it gives me the ability to throw it on for a stage if I'm shooting a match and something about my dope seems wonky.

It does display the error message from too much movement when getting into positions many times (and that may explain my literally few errant shots that didn't get picked up), but 99.9% of the time, if I'm actually doing what I should be doing and getting the rifle stable before I break the shot, it (nearly) always gets it.

Same here.
 
We took two and tested them in various places and distances... even made a video of it with 22lr one day

Short answer if the thing gives you a speed it was pretty much dead on. If you got too far away from it then it'll just "think" and not record a shot

I use the gray ops mount if am messing around with positional shooting or tripod. If am benched or prone I’ll just do the factory tripod mount, either way the thing has never missed a shot of 22LR, 5.56, 6.5CM, or 7 PRC.

Not sure if it was an update thing but before if I had a string of 20-30 rounds and I got one or two rounds that were either really fast or really slow and would mess up the average I could go into shots and delete them. This would bring my SD back to what it should be. Now even if I delete those two shots the SD and average does not correct itself.
 
Does anyone have tips for using the Garmin with suppressed 22 pistols? My Garmin is only a few weeks old and have had good luck with subs in rifles.
I want to test some different subsonic 22 ammo through screw on's and 1 or 2 integral pistols. Will be shooting from a bench and can vary distance to target.
The CCI Quiet is listed as 750fps, CCI Subsonic is listed as 1050 fps, the CCI Standard Vel is listed as 1070fps, and Winchester Subsonic Segmented is listed as 1070fps. The Winchester "sounded" like they were supersonic through both screw on and integral. I can't find any CCI Subsonic Segmented local to try.

Thanks
 
It shouldn’t be a problem if you use the pistol/low velocity setting. I cross checked the velocity of a single cock bb-gun and was registering velocities in the 300 fps range.

As for CCI Standard Velocity, I was getting about 50fps slower than the box velocity at 3200 feet above Sea Level and 35* F. This was from a 22” Marlin 39 rifle.

I’ve gotten sound repeatable data on 177 pellets at 380fps.

Unlike the Labradar, “suppressed” or not should have no effect on the Garmin’s ability to pick up shots. It doesn’t use sound to trigger it like the LR does.
 
Do you get a motion error message with the Garmin mounted on the diving board, either from recoil or getting into firing position?
Yes, it will throw a movement error message if I move the rifle off or onto the tripod. I was initially worried that the stated 5”-15” distance would be too short to pick up the bullets on my longer barreled rifles but it has worked flawlessly beyond the 15” range. Recoil has never caused an issue.

Yep, picks up BBs too.

Just to add to the list of variability of the Garmin I tried it with a paintball gun as well and it picks it up no problem and I was surprised at how far away you can be. I'm talking way more than the 15" in the little diagram screen it gives you when you setup to start your readings.

Paintball- now there was a previous passion I haven't heard mentioned here. Anywho- not surprised that it worked, the Xero is quite possibly the biggest game changer/market disrupter of the decade that I'm aware of.

My battery has degraded a bit since new. I can still get a solid four hours but I've resorted to charging it in between range sessions just to make sure it's topped off. It didn't seem to charge to 100% for a bit there either. Haven't checked it lately but I plan on bringing along a battery pack for longer sessions in the future.
 
I wish they’d have made it with regular batteries vs rechargeable. But of course that’s the future with everything. A battery pack can be had though, but as I stated it lasts enough for how I use it. I mean you shouldn’t be having to use it continuously e every time you go shoot. It’s good for load development and for ballistics calcs.

After an hour of use it’s down to roughly 2/3 or 66%.
Well they’re batteries and every record is uses them, so in my book? It lasts long enough. Need more time? Connect it to a car battery if you’re going to spend 6wks at the range shooting continuously I guess? I mean you’re complaining of battery usage. Buy a Caldwell sky beam with batteries or maybe magneto? Or Labradar. Idk what to say. Product works as intended and works damn good. If battery is the issue figure it out

I use mine all the time.

1, that why I purchased it.
2, you can learn so much from the data especially 22lr. Have a flyer, look at your speed. Chances are you will see a difference in velocity. That you can't control, you chasing it. That is something you can now control.
3, center fire, get so many rds on a cleaning. You see velocity change, you can clean and see a difference. Again another data point to keep you from chasing your tail.

Can only speak for myself, the more data you have the better decisions we can make. Actually have 2, the both get used all the time. The money is spent, my plan is to get my money's worth out of these units. If one shit the bed, I would replace it today. They are that valuable to me.
 
How is everyone’s battery life? I feel like I am having to recharge it every other range outing. I expected much better.
Dunno...I use a battery/power bank with it every time. I use a Cole-tac case that has a pocket on each side....chrono in one side, battery bank and USB cable in the other side, and it has a strap in the middle for the little tripod.

This is, IMO, the way to go and something I started doing with the Labradar and its ridiculous consumption of batteries.

Power banks are reasonably inexpensive and this way I'm not jumping around pausing sessions during barrel cooling breaks, etc.

Just a thought.

Simmer down there big fella, I made a simple inquiry to see how others were getting along with theirs as I have a sample size of one. I didn't come in here throwing a fit and demanding worlds better so cool it with the accusations and assumptions. I have used it all of four range sessions and it has never made it past four hours of use, that seems a bit on the weak end of things in comparison to my other small Garmin devices, hence the inquiry. I am glad to hear that you're enjoying yours, I am enjoying mine as well aside from the short battery life.
 
Surely a battery bank makes this a non issue?
Everyone with a LR had one anyway and it's still a considerably small more compact package than a LR or MS.

The internal battery only has a 820 mAh capacity so even the smallest power bank with extended the battery life 500%.
You could even get one of the 18650 battery holder/chargers, the capacity of most 18650 cells is at 2000-3000mAh.
