does the angle of the moving object through the radar beam matter....head on, across, directly away ?

Yes ,, it needs to be coming pretty straight at you and at not much of an angle or distance.On the field behind the catcher is more accurate than behind the backstop,unless the backstop is fairly close.

Tim, Thanks for the question. This is a very important issue. Yes, the angle is very important. All radar guns only measure "relative velocity". What that means is that you will only get the true speed of the moving object when it is moving directly towards the radar beam or directly away from the radar beam. As you go off in angle the speed readings will show lower than the true speed due to what is called the "Cosine effect". This is the reason that the police have to be alongside the road in-line with the traffic to use radar, they cannot use it sitting down a side road with the traffic moving across in front of the radar. As a simple rule of thumb, if you are within about 10 degrees off-angle with the path of the moving object then the readings are still within +/- 1% of the true speed. As the angle increases beyond 10 degrees then the error increases very quickly. This angle issue also applies in the vertical direction, so you need to be careful not to tilt your radar gun down too far as well. Please let me know if you have any other questions.

About 30 degrees or so. Still has to be aimed at the antenna array you want to pick up.

Keep in mind that when taking a reading on a vehicle, you will only get an accurate measurement if the vehicle is coming directly towards you (you're standing in the middle of the road). Radar Gun will not compensate for lateral movement as a Police Radar gun will.

If you are looking at an upward of downward angle, it does change a very little bit. Not from side to side though.

Most likely he had radar off - it only detects radar when its on - it will definitely work, mine works just fine, even at a distance and over hills etc.

If I understand your question you're asking if it will clock speed from a side angle while throwing to a catcher. If that's the question I would say no. If you're asking if throwing towards it as its intended but with a catcher catching in front of it, I've done this. It picks up provided nothing blocks the radar. But also the calculations are distance dependant so the unit still has to be set at the proper distance while the catcher would have to be closer to the pitcher and again not block the radar. But with no catcher, standing the proper distance away, pitching and hitting anywhere on the target area or back screen, it will give speed and call balls and strikes very accurately. Good product.

A forward facing antenna is what this detector is equiped with. That being said only the Valentine One has a fore & aft antenna. A 360 degree sweep would require a rotational antenna that rotates 360 degrees. You are unlikely ever to see a sweeping antenna on a radar detector designed as a speed countermeasure.

Don't know really. Not sure why it should have anything to do with a radar detection device. It is a communication device one uses to communicate with other skiiers/snowboarders on the slopes using a similar device.

It depends on how far away you are. I found the further away, yes. It was about ten feet that you do have to point towards the receiver.

I strongly doubt it. Since it depends on suction, it needs a smooth, non-porous surface and the detector only works when it can "see" the incoming radar/laser signals.

My understanding is that you font have to point it at the strongest signal area directly. Height is most important for success, not trying to aim the point of the antenna at strongest signal direction

For the most part, yes, it is line of sight only. If there's small objects momentarily in the way, often times the signal will make it around or through it (like a small tree) but for what you're trying to do with it, signal would most certainly be lost. There are, however, ways to make this drone autonomous by adding additional equipment and using software called "Mission Planner 7". for your particular application something like that would be best suited.

I would guess that it picks up radar 2-3 miles in advance if they are pinging other cars. as far as updatable, I do not know since I just purchased mine recently but would be surprised if it was not

Yes, as long as you are within range and you can see the laser dot on the next pole so you know you are measuring to it and not something behind it.But considering alternatives to taking that measurement, this would be awesome.

It will detect movement 360 degrees directly below the sensor in an umbrella-type coverage.... Otherwise, It can only detect motion 180 degrees.

Based on my experience with the product I doubt it would. The radar needs a clean line of site, and you basically have to come close to hitting it to get a reading.

Agree with 1200 feet maximum under ideal conditions.... Listen, you will lose orientation because the plane is too small to see before you lose signal.
