The eighth wonder of the world, the Garmin Xero C1 Pro chronograph

You can't throw out the extreme values before computing your SD and ES. That's cheating.
It's like ignoring the "fliers" on your group on paper and then measuring group size. Cheating.

I had thought the same thing. As a data-driven person I couldn't wrap my head around why you'd want to exclude data from the dataset unless you were trying to fudge the numbers in your favor (which seems to be exactly what he has done, regardless as to whether that was his intent). More data=more accurate results.
 
I don't see how you figure the battery will be unusable after 3-4 years. I have many rechargeable small Li batteries that are more than 4 years old and yes, they don't hold as much of a charge but they work just fine.

This. I don't know that I've ever seen a device that wasn't neglected that had a battery degrade so much that it wouldn't function at all. I have old phones kicking around that I charged and discharged almost completely on a daily basis for 4+ years, and they will still turn on if i plug them in. Seems like kind of a weird thing to be worried about.

I have a Samsung Galaxy S2 that still turns on just fine. Release date on that model was in 2011. Its useless because none of the apps are supported by now - probably won't even open youtube at this point lol - but it functions.
 
You do need to account for those "fliers" that pull the SD numbers out, since the same can happen during a match or while you're engaging wildlife. Does it mean dodgy primers or a loading error? Some things can be fixed in aid of more accurate and consistent shooting.
 
Thanks for the write up.
One of my concerns was regarding cold weather operations. I finally found where it would operate in temps ranging from -10 to +55 C.
I purchased mine the other day and am looking forward to its arrival this week. Weather should be good for getting out to shoot a few rifles after it arrives. I too am looking forward to the simple set up when using it, and no chance of hitting the screens when moving from target to target on the backboard and forgetting to recheck the screen clearance (may have only happened to me once, but it was still an aggravation, and ended the data collection for that range session! LOL).
Glad to hear that other shooters at the range aren't affecting its recording of the shooter's data collection.

My only other outstanding questions is regarding it's reading of all shots under less than ideal lighting conditions. I have found my chrony sometimes has issues getting readings when lighting conditions are changing during the course of the shooting session.

Being a radar system it is not affected by light.
 
Thanks for that. I'm wondering if the internal is down to zero will it run off the external or is it just charging the internal.....

Once the unit battery is low enough it won't run try plugging in the external and see if it turns on right away or if it 'charges' the internal battery first.

I know from iphones these small Li batts usually last 3-4 years, not sure how they wired up the Garmin to handle a dead internal batt that won't take a charge. If an external unit works then there is no worries down the road.

Unless you are doing daily chronographing you're not gonna be anywhere close to the number of charge/discharge cycles that a phone battery sees. As long as you don't leave it out in the cold (how I killed by previous phone's battery) or extreme heat for extended amounts of time it'll be fine.
 
I tried mine out for the first time this morning. My luck with chronographs in general has been poor, I'm usually astonished when one works at all, and more than a little surprised if the stated velocity matches my actual drops.

So; back to the Garmin. Charged it up over-night although it was 75% charged when I got it. Turned it on, did what the screen told me and took about 100 shots. Never missed a single one, and set-up as easy as falling down a well, which is generally regarded as something that requires no talent or special skills.
 
Any Buddy run there battery right out yet ? If so time run or amount of shots before shut down . Thxs RJ

Not yet.

But I have had it out several times and have well over 100 shots per time, with hardly a dent in the power consumption. 2-3 hours out is no problem with it. I'm purposely letting it run low now, so I can try it out at the range plugged in to a battery pack for charge at the same time and see what it does.

I did see that I had maxed out my sessions on it the other day, and was cautious about deleting any on the unit. Well over 40 sessions from what I remember, and didn't look to see how many sessions exactly on it to max it out. Just counted my sessions on the app, and figure it store 50 sessions on the unit before it is full, and then over writes the oldest session to start a new one. So keep that in mind, you need to link to the app to download before you lose the sessions.
I start a new session each time I grab a different rifle while at the range. Shoot 3-10 shot string, change rifle to let the first cool down, etc. Usually have 4-6 rifles on each visit, just because, so you could imagine the sessions I see per each range visit. My average so far has been 12-22 sessions on the 3 times I've used it. I usually grab my 6.5 CM bench rifle each time I go to our longer range, and will shoot a 50 shot string with it as well, and those are included in those sessions. I imagine that it has a size limit on the internal memory, ie limit of sessions, and combination of shots per session, but I have not run into any issues running 50 shot sessions in between the other smaller sessions, and just the session max of 50.

I usually link to the app on the phone after the range trip and get all the info over to that, and then add my specifics onto each session. After deleting a few sessions on the unit and seeing no difference on the phone, I deleted all my sessions on the unit, and now I'm good and fresh for the next use. Once in the app, they are there until you delete them. I don't remember if they stay in the app if you export them, I'll have to watch for that next time I export.


As I said before, my only problem with the unit is getting used to not doing mag dumps while using it. I never used a chrony before this unit, so still have to get used to that. I practice mag dumps on some bolt actions, just because, you never know what you will run into while out in the field. Yep, my 77/44 gets a 5 round mag dump once in a while. Some of my levers do as well.
 
Quick note on the internal battery.

Today I was out with mine. It was damn cold today. The temperature inside the enclosure at CHAS was close to -10c. I ran the Garmin for three hours non stop. The battery drained to 74% remaining when I was done.

And the pause function works very well. I was at the 100m enclosure for an hour and a half. Then I paused my session and turned the unit off. I moved to the 800m enclosure and turned the unit on and continued my session. It did show the second portion in a separate session on the ShotView app. But the original still had the total of all of the shots from both times. Just a little extra to look at.

I’m still impressed!

In all the time since it's introduction they did what, a software update, two less than stellar app updates and added Bluetooth? No wonder everyone is dumping them.

Labradar is still a great unit compared to everything else out there except the Garmin
 
Someone from the snipershide forums took one apart. Looks like your average 3pin JST LIPO battery to me, the trick is finding a replacement with the correct voltage and similar size.

3.7v 820mAH which is super common in small handheld gaming systems, shouldnt be all that hard to find replacements. Doesn't list dimensions on the wrapper which is uncommon for these types of batteries but nothing you couldn't measure yourself.

Edit: Should have read his post fully, guy also links to a suitable replacement.
