Garmin Xero C1 Pro Chronograph

Took the brandy new Garmin to the outdoor range for first try. Charged the battery first, easily fit into range bag (larger hard tool box). Fast to set up, got position right on first try (really easy) and used it to chrono some new 45 ar loads. It never missed a shot, briefly taking time to calculate the result. Have no fancy phone, but unit does not need one to operate and i just wrote down the velocity's in book (no batteries/internet required), and reset session after each string. Am not needing B.C. calculation for my purposes, someone else's purpose may differ.

For my purposes, the ease of storage/transport/set up/use really helps. The reliability of getting a velocity reading is huge. In the future, am wondering how long the battery is good for. Sure it's expensive, but my actual shooting time is slowly running out and not patient enough to wait for cheaper prices or competition from other new copied models.

Will try it on indoor range at first chance, and the much smaller dedicated indoor range bag still has plenty of room for it.

Wish as i might, will not be able to get back all the time/effort messing with the old chrony. But will likely chrono much more as it is no longer a pita.
 
Well made it to the indoor range today, which has it's backstop at 25 yds and divided shooting booths. Large paper silhouette target at 25 yds and the Garmin didn't miss a shot, although it seems a little sensitive at the indoor range and went into a repeating analyzing phase. Moving it a tad and resetting fixed it, and not sure what caused it, but the range has a more modern air moving/filtering system.

Got the results i wanted at 75 feet, so moved it up to 50 feet. Again it didn't miss a shot. Then moved it up to 25 feet, and yet again it didn't miss a shot. Am not knowledgeable about how it works, but am guessing having it set to the side a little allows it to calculate the whole way to 25 yds? Anyway, it worked at 75, 50 and 25 feet inside when the backstop was 25 yds downrange.

Good data zeke.
 
Well done, zeke.

Does it give you the velocity at whatever point downrange that it picks up the projectile or does it automatically calculate back to the muzzle? Or both?

Any differences in the reported average velocities for each target distance or all pretty much the same?

Only had one shot of a load combination that was tested at 2 different distances. The shot at 50 feet was right in the middle of the rounds fired at 75 feet. The next powder combination was shot at 50 feet, and another bullet tried at 25 feet. Maybe next time will shoot same combination at all three distances, but none of the results seemed out of line.

sorry, but I have no clue how/when it picks up a bullet in flight.
 
FWIW, I have used the Garmin and the MagnetoSpeed simultaneously a few times now. And I have used the Garmin at 45 feet, on steel (to eliminate that it is picking up beyond the target). Not a single missed shot and I might be ready to sell the MagnetoSpeed.
 
Late to the party. I bought my Garmin last November, had to set it under the tree, and finally took it out to the indoor range 2 weeks ago. I’ve never used a chronograph. Figured I’d run into some kind of learning curve as to placement and aiming. Nope!
It did miss a few shots as it triggered off the next lane…but didn’t calculate any shots not from my lane. So if I happened to shoot just after the next lane did, the Garmin was already triggered, thus missing my shot.
I recorded 22 sessions of mixed 6.8 SPC, 6mm ARC, 9mm Luger, and even some 22LR for grins.
Aiming just needs to be straight down range. When changing magazines I nudged the Garmin a bit…so it was pointing a tad to the left…and it missed 2 shots till I figured it out. No fancy, specific aiming needed…just perpendicular to my lane.
One quirk…it would only sync pistol sessions to my Android phone, and rifle sessions only to my iPad. Garmin support had no answers…just advised me to only sync to my iPad.
 
Interesting... you are the first report I've read of the Garmin missing a few shots. What was the offset of the Garmin from the muzzle of your firearms when you were shooting? In general, the closer the unit is to the muzzle, the better that a radar chronograph will operate.
 
I took the new Retrograde out today to try it out.

I had some 1oz target slugs to shoot. Notice that there’s no speed printed on that label.

Now, I’ve never chrony’d a slug from a scattergun. I tried it once with a LabRadar and I wasn’t surprised that it couldn’t pick up the big chunk of lead. Someone at the range told me that only slugs with the wad glued to the lead can be picked up by the LabRadar. It seems to get confused with two pieces flying down range.

Enter the little Garmin wonder. The Garmin only picked up 19 out of the 25 rounds that I fired. To be fair, I believe that I was moving away from the chrony as I was firing. And I got too far away from it. I’ll give the Garmin the benefit of the doubt. Now, just look at those spread and SD numbers!

The fellow shooting next to me was jealous with those numbers. I was amazed. That is pretty consistent ammo! And it’’s just cheapo target grade lower recoil shells.
 
Good consistency! I assume you missed getting a ft-lb measure because you didn't enter the slug weight in grains (437.5 grains per ounce). At your average velocity with a 1 oz slug, it works out to be 1565.3 ft-lbs.
 
Yes that’s correct. I forgot to get the conversion and figure out the weight of the slug to enter into the Garmin. And at the range I was at, the cell phone coverage is non exsistant.
 
It's an easy conversion if you remember there are 7000 grains in a pound and 16 ounces in a pound. To get an ounce in grains, you just divide 7000 grs/lb by 16 oz/lb. The pounds cancel, and you have 437.5 grains per ounce. (I am just putting that in your head in case you forget the 437.5 number next time you measure slug velocities at the range.)
 
Yeah thanks, I already knew the conversion and the equivalent gr/lb. I just didn’t have it with me at the range and couldn’t access it because of the lack of cell coverage.

I’ve got it now in my iPad (which is my range computer).
