Lets see your lab radar do this!

[Benchrest Braxton]

I got the idea from Greg at primal rights youtube video when he put his garmin 50 yards down range.

I noticed my 223 wasn't setting off tannerite at 300 yards reliably so I wanted to get some actual velocity data.

According to my ballistic software, my load still had an impact velocity of 2,500 fps (minimum required to set off tannerite).

I am running the 53 grain vmax in my 12 twist factory remington, when you put this into a stability factor calculator, it is right on the edge of being able to stabilize (Sg of 1.0).

I thought this was the source of my issues, my velocity being lower than I expected because of the bc degradation due to the stability being poor.

So I decided to stick my garmin 302 yards downrange on my tripod and check the numbers vs my sig bdx software. My rifle shoots 1/2 moa very consistently so I wasn't worried about potentially hitting the unit.

I placed the target 13 yards past the garmin downrange at 315 yards to give the doppler some room for the signal.

I took 3 shots, went down to the unit, and had 3 shots registered. Not a single hiccup.

To my surprise, the unit matched up perfectly with my ballistic software. Very nice that this unit gives me the ability to confirm numbers downrange so easily.

This garmin unit has yet to disappoint!!!!!

Nice!

 

[JFrank]

Very impressive…

Neat test! This is probably the end for Lab Radar.

I thought the lab radar would give down range velocities, I could be wrong.

I thought the lab radar would give down range velocities, I could be wrong.

It does under good conditions give velocities to 100 yards.

Why couldn’t a Labradar be positioned downrange like a Garmin?

How would you trigger the Labradar?

No idea. How are they triggered?

It can. I wont say it does it very well. If you extend the distances out past the defaults (44 yards, I think?) it gets very fiddly and will drop shots.

 

[dgeesaman]

No idea. How are they triggered?

It might work with the airgun microphone trigger, but the airgun microphone trigger is for subsonic velocities. Or you could rely on the Doppler trigger setting.

The real question is how you’d arm it - I suppose you could set the arm time to maximum, walk back, and take the shot. It can also be armed using the Bluetooth connection but I imagine the Bluetooth range isn’t that far.

As for real world applications, I don’t think anyone really *needs* to diagnose tannerite impacts, but it would be cool to accurately capture velocity of shots passing over the target bank at long range and compare that to muzzle velocities.

I saw a garmin on a seb X last week. Looked like it was made on the rest. Very impressed....

 

[Timberyote]

Nicely done, congrats.

I hate to be the fly in the ointment, but the LabRadar can and does do that from the bench. No need to go tramping down range and be in fear of killing your chrono. LabRadar records data on a projectile until it either goes out of range or stops. I get an average of 102 readings on a handgun fired on a 52 yard range. These readings are saved onto the SD card and are available at your computer. Additionally your have the option of selecting 5 yardage ranges that appear on the screen of the LR during a shooting session, so if you need instant feedback you have it.

Yesterday two shooters took my Garmin off the bench, set it down on theirs and shot. No need for the tripod. Just set it down. They were both surprised at the perfect operation of the Garmin. Both had Lab Radars and both did not bring them because of the bulk and PIA setting up the Lab Radar.

Now you got me thinking about this. Wondering if I could position my Longshot camera with both the Garmin and target in focus at 600 yards. That way I could read the velocity downrange and see target impacts.

Looks like 2500 is the magic number. I guess you could move it a bit closer to verify.

It stops at 100y.

what's so difficult about grabbing the tripod/LR and moving it bench to bench? Just pick it up, move it and set it down. I'll grant the bulk of the LR but it never stopped me from bringing it to the range. But set up takes about a minute.

The size of the garmin is nice but not enough for me to go out and replace my LR.


What triggers the Garmin when sitting next to the firearm?

So, where did you aim concerning the Garmin?
