Garmin Xero C1 Pro chronograph

How is everyone’s battery life? I feel like I am having to recharge it every other range outing. I expected much better.
I can do two 4 hour sessions with my Garmin before recharging, but those are bolt action sessions and include 10-minute cease fires every half hour or so. That is pushing the battery limit though. For a radar the size smaller than a cigarette pack that is amazing, The battery must be very small.

The caveat comes with semi autos - ARs. I fire my AR much faster than my bolt gun. The unit has to turn the radar on much more often and although I have not seen huge battery drain differences I'm sure more frequent firing has to have an effect on battery life.

To the best of my knowledge the Xero does not turn off the radar between shots, it’s always on, that’s why it doesn’t need a microphone or recoil trigger to know when you’ve fired. Any change in battery life with a semi-auto would just be from it having to compute velocities more frequently, and presumably that is far less power-hungry than the radar system.
 
sure they could have used higher capacity batteries, but then price increases as well.

It's as big as the size allows. If they put a massive battery in it everyone would complain about how big it is.

I plug mine into the truck since I already have 8 USB cords in there. I just hit it anytime it is getting low, and it easily lasts all day.

I agree. Good points. (y)
 
I like to let them cooldown after use before charging too. Not sure if it matters but it seems like a good idea. I did not know about the cold.
Yeah. I murdered a new Ryobi battery in one year by leaving it plugged in over the winter in MN.

The rechargeables tend to be able to withstand sitting in the cold, but as mentioned, charging in the cold (under 32°F) is tough on them. I think you’re right about the heat too, like charging them in a hot truck during AZ summer (but don’t quote me).

As far as 18650 rechargeables for thermals and headlamps etc, I have read that just using them in sub-32°F is hard on them too. Not sure about other rechargeables…but that’s not going to stop me from simply using them in the cold.

Obviously batteries are ultimately disposable, but I try not to hasten their eventual demise by cold-charging.

This reminds me of my rage against 12Ah Milwaukee M18 packs that died just outside the warranty. Fucking hosers.

old-charging was involved, but I forgot to mention that I take all of my chargers inside for winter charging.
I use my Makita
It wasn’t they’re just shit.
I use a Makita 3-amp, 18-volt cordless 2 maybe 3 times a month and I can't remember how long it's been since I charged batteries. It' incredible at holding a charge. The box lives in the garage which unlike further north it only sees winter temperatures in the mid to high 40-50's every year. Just yesterday I took down the flourecents (pain in the ass changing tubes) an installed all new ELD ceiling lights in the garage. Brightest damn room in the house now! Used same battery I've been using since July.

Best cordless drill I've ever used. I've never had to buy a new battery in over 8-years. Buy once cry once.

The radar DOES turn off if you're not in an active session. If you start a session and let it run all day that would be worst case battery life. If you shoot and then end or pause the session until you need it again it will greatly extend the battery life.
 
I saw a few references in this thread about use at indoor ranges, mostly short pistol ranges. What is the likelihood it would work well at a 100 yard indoor rifle range where the walls, ceiling, and floor are concrete, and you may have another shooter within 5 or 6 feet on each side of you?

Should work just fine, at matches with people on both sides of me. It only reads my shots.

Yeah I did not mean the radar is on at ALL times, I thought that was obvious. I was just correcting the previous poster who said the radar turned off after every shot in a string.
 
This only started happening recently. Just a minor inconvenience to have to delete a dozen or so duplicates every now and then, so no complaints here.
Have you tried a factory reset?
  1. Turn off the chronograph
  2. Press and hold OK and XeroC1DownArrow
  3. Press PWR to turn on the device
  4. Release OK when the Xero logo appears
  5. Continue to hold XeroC1DownArrow until the device starts

I have not, but thank you for that information. I will definitely try it.

Received emails today from Area 419, Brownells and MK Machining. All have the Xero C1 on sale for $549.99. A google search shows that almost everyone is selling at $549.99 now.

I wonder if this is because the Athlon Rangecraft is about to hit the streets. Or perhaps they're trying to dump inventory before a new release...

That's a very good question.
 
Put my review of the Garmin Chrono up today after a year of use. It's been a lifesaver I never would have gotten some of the data I ended up needing on the 350L without it and I am certain I would not have gone down some of the investigative paths that have been fruitful without that data. It is really nice having a chrono that is easy and reliable even if I don't love some of their design decisions.
