LabRadar question

[Terry wickenheiser]

Have they upgraded their ap? The one I have/had you can only see current shot that's on the Labradar. You couldn't do anything from your phone. I was in the first batch of people to get this unit and the R&D has been kind of slow. It took a couple years to get the blue tooth to connect. Being able to go back and forth between strings would be awesome. One could do load strings up prior to going to range. (their solution was have separate sd cards for each string.) Showing Ave power factors in each string would also be nice. The competition hand gunners would benefit from this. Also a better aiming system would greatly improve on the accuracy of the unit.

I've had no problems with triggering or tracking, with the muzzle as far as six inches in front of the unit.

Will the 6 inches skew the velocity curve when calculating drops or BC from V0? Or just use a distance like V5 (5 yards)?

The version I have is capable of controlling all the features that the buttons will do. It's still pretty terrible, and you can't revisit strings, name them, or add notes. It's still better than pushing the buttons though.

I don't think it should cause any trouble, and I haven't noticed any issues. It takes 10-15 milliseconds after the shot to trigger and start receiving data, so the bullet has traveled 10-12 yds before it receives the first tracking data. V0, and any distance you set inside that, is calculated by extrapolation from wherever it starts tracking the bullet.

This is why you can sometimes get really wonky data for V0, but good data for the rest of your set distances. If the unit has bad tracking for the first couple of milliseconds, it will extrapolate a nonsense velocity from those first few points. Once the tracking settles in, it does fine from there on out.

I have a data culling spreadsheet setup, which regresses a line through ALL of the data. It can use the equation for the regression to calculate the velocity at any distance, and greatly reduces the influence of a few bad data points.

Do you have your unit set on Internal Trigger or Doppler trigger?

I use the internal sound trigger, not doppler. According to the manual, you should only use doppler for large/slow things (arrows I assume).

I purchased and have been using a LabRadar for over a year now with zero problems. When shooting my handguns and rifles, I use the internal sound trigger. A fellow shooter on the range recently wanted to see how fast his pellet rifle was kicking out his pellets. I switched over to doppler mode and had no problems again obtaining velocities for his pellet rifle.

I was going to order one yesterday but, my daughter said, "don't". Your birthday is in 5 more days. I have such a good daughter. LOL.

I would like to take this opportunity to ask you for your daughters hand in marriage......

 

[tbrice23]

Five frustrating range sessions in and it has already crapped out! I'm having to send it back already! I would not suggest anyone buying this unit!
Someone needs to give these guys some product competition.

Sorry. She is single but, I don't have everything I need just yet!

What advantages does the LABRADAR have over the magnetospeed V3 when used with rifles like the .375CT, the .408CT, and the .50BMG? I did some load development for my Desert Tech HTI in .408 today and I was getting errors (sensor 1) from the magnetospeed despite everything being set up per the instruction manual.

This magnetospeed issue is making me wonder if I should go and buy the LABRADAR or just replace the bayonet on the magnetospeed.

Does the cell phone ap on the radar unit display individual shot speeds and ES for any given string?

You don't need the cell app for that. The LabRadar will do that for you right on its own screen. You can also download the data to a PC and use Excel to analyse the data including velocity traces for each shot, etc etc.

I believe that the primary advantage of the cell phone app is convenience. The phone app makes it possible to execute functions from a phone screen on the shooting table right beside you. You don't have to reach way over and touch buttons on the LabRadar itself which is up front beside the rifle muzzle. Shorter shooters might even have to get up and walk around to do that.

In my opinion, the LabRadar is not just the next generation of chronographs. It's a whole new paradigm. Buy one - it's a lot of coin but worth every penny.

Thank you for the info

On the magnetospeed app I can enter in bullet weight and other data for each string. And I can do it immediately after. Can the same thing be done with the labradar?

How do you position the radar in relation to the muzzle break of a large bore rifle such as a .50 BMG?
