and I suppose you are confident your lab radar is picking up the bullet at the same spot every time you set it up. If so you must be using a measuring tape to ensure the radar cone vector is aimed at the same spot every time. I use a tape measure for my Prochrono and a small piece of foam display board with a dot drawn on it so I set up my optical for the bullet to pass over the sensors at the same height and the same distance each outing. Takes me about 5 minutes to set it up from the time I unzip the carry bag, but I know every time the bullets are passing over the unit exactly like they did the previous session. Can you say the same ?
all Caldwell would have to do is give the unit a bluetooth that works, a vibration trigger, and rechargeable battery and their quality and price would beat the LR. Give it a decent aiming system, a steady benchmount and throw in a carry case and they would have surpassed it by miles
I can see that you don’t have a clear grasp on the two technologies (light curtain vs Doppler radar technology) so I won’t get into the specifics but aiming a LR is FAR easier than people would lead you to believe. Yes, when I set up I measure the exact distance to the LR although it isn’t as finicky as you believe.
Try setting your chrony up and shooting a 20 shot string. Then completely disassemble your chrony and set it up again, then shoot another 20 shot string and compare the results. I can do that with my LR and get the same average every time and a SD that is within 1.0fps, can you?
So true. The LR is just a tool for me, the target has to be the final decider. Some people are so tied up on getting low ES and SD that they forget what the target is screaming at them.
Wel if you set it up so the radar cone is picking the bullet up the same point it will. Change that vector and I can guarantee it wont. That's just common sense and first year trigonomics. Consistent setup and pickup is needed for any chronograph to be consistent between sessions. I can guarantee that the ProChrono is doing that using nothing more than a tape measure which I keep in the range bag at all times and a small piece of cardboard for the old laser bore sight to shine on. That is also one of the main draws of the Andiscan for me. Being able to mount it on my rifle or rest so that the angle of the cone picks up the bullet at the same point in flight session after session plus its small size and other features that the LR just either does not have or cannot get to work
Lol. AGAIN, clearly you don’t understand how Doppler radar works. As long as the bullet is captured in multiple positions throughout the cone, it will give you the same velocity. Try having your prochrony at +/- 2deg and see the difference. While your prochrony is susceptible to the laws of trig and the effects of angular placement and perpendicularity of muzzle to light curtains; the LR is not because Doppler allows it to capture the X, Y and Z coordinates of the projectile at multiple positions. Your prochrony is nothing more than a glorified stopwatch. I can’t debate the pros and cons of each if you refuse to understand the technology; so why don’t we just agree to disagree and I’ll keep using my LR and you can keep waiting until the cease fire call to setup and tear down your chrony.
I totally get where you’re coming from but keep in mind as I said in the video it was a beta unit. I actually have a second generation beta on its way to me and because of my feedback he has corrected nearly all of the initial minor issues. As far as pricing goes, it’s really not that much more than a LabRadar. His plan is to be in the $800-$1000 range and considering a LabRadar is $600 but you still have to buy a base, trigger and some kind of case plus a battery pack, that can usually add another $100-$200 to your LabRadar so the price difference isn’t really that much considering the AndiScan will come with everything you need out of the box. I’ve been doing a lot more testing on and off the gun both with good results and will have some more videos as soon as the second unit arrives. I honestly haven’t pulled out my LabRadar in several weeks now because this thing is just to handy to throw in your range bag.
actually I think it is you that does not understand basic ballistics. If the radar catches the bullet the first time at 10 feet or if it catches it the first time at 15 feet there will be a difference in its muzzle velocity estimates. I am aware that the LR uses multiple readings to estimate the muzzle velocity but if you look at the chart I posted above the algorithm it uses is not accurate. It's estimate for the 10 shots was only .2 FPS higher than my Prochrono which was set at 12 feet from the front of the bench to the front sensor. The Magnetospeed was 15 FPS faster at the muzzle. If you take the BC of that bullet and put in the Magnetospeeds 3125FPS as muzzle velocity the plug the data into the JBM ballistic computer you would see that at 10 - 15 FPS you will lose about 15 FPS at that distance. To me it is obvious that the LR's estimate came out at 10 - 15 feet from muzzle.
Thanks for confirming exactly the point I was trying to make.I own a optical chronograph, a Magnetospeed, and a Labradar. I shoot on public ranges, and the OC was such a PITA to set up, that I rarely used it. Skipping the OC due to the extra hassle of set-up shows that a chronograph is not essential for developing an accurate load.
The Magnetospeed can be set up on a hot range, is easy to use, but it attaches to the barrel and so affects harmonics. Still, the MS is a good reduced-cost option.
The LR can also be setup on a hot range, is easy to use, and doesn't affect harmonics. The LR is so easy to use that I pretty much always use it. I frequently use the MS and LR together on the same shot, and they produce readings within 2-3 fps of each other for ~3000fps MVs, which is within the stated error of each machine. I have an inertial trigger for the LR, but rarely use it because I don't have problems getting the unit to trigger off of its acoustic trigger, and I don't get false triggers from adjacent shooters. My only complaint with the LR is its 3900 fps limitation, which I bump up against with my 22-250.
To each his own, but for me, the LR is the preferred option because it is easy, accurate, and doesn't touch the barrel.
You keep doing you, and we can agree to disagree. I suggest you bone up on Doppler radar as it takes into account the angularity of the muzzle to the radar cone. Keep using your PITA optical setup and I’ll keep enjoying 21st century technology.
Dave, I'm not specifically privy to the IP of the LabRadar processing or their software, but will offer a guess that these (LabRadar or Andiscan) instruments are one dimensional Doppler, not three dimensional tracking.
I realize it has some limitations and isn’t ready to go out of the box, but once the correct setup is dialed in (much like your optical unit) it works great. The Arko machine LR quad base is awesome.
