All radar detectors were mounted on the same marked position of the windscreen each time, and all were mounted level.
Next time we do a similar test, We'll use two video recorders, one behind the laser gun, and one inside the car.
I thought it was much more important to see through the LTI HUD than inside the car, hence the use of radios to hear the detector's alerts.
The downside to using two cameras per test is footage time. We already went over 10 minutes on three of the above videos, and had to cut them back so YouTube would allow them to be posted. In the 200m test you'll notice the titles for each test are cut real short! We had to do this to get the overall time down.
I agree with you there was some "bounce" in some of the tests. The operator repeated any that he thought would be skewed from the bounce.
Next time, we'd like to make a camera mount made that holds the video camera to the back of the laser gun, and then have the whole set-up mounted on our tripod. This will reduce the laser bounce that we did get in some of the longer range shots. It may not have been perfect, but it was our first attempt and it's hard work holding the camera steady for all that time. At least everyone can see with their own eyes exactly where the laser is aimed at, and the results. Our objective is always to back our results with video footage. |
