Are detectors without side arrows missing much

My detector only has arrows for front and rear (beltronic gt360 and dualpro 360). Are the side arrows on the max360, v1,r7, etc really something special I'm missing.

I see that they both flip to the sides when you pass your source or get pretty close with is nice.

I see them transition, but like all things a bit delayed.
I see them light up when right beside a door opener signal.
They came in first with the voice saying SIDE, a few times when I was perpendicular to the source.
I don't think they are make or break feature, but if you go through the trouble of arrows why not.
Just some extra display info.
Visually different than having front and rear arrows light up at same time.

As I am usually moving at highway speeds when using my V1, the side arrows typically don't flash very long as the signal moves from ahead to behind or vice versa. The one time they are useful is IDing a car with a BSM or leaky detector which is setting my detector off and moving in the same direction.

They only come on when the signal reaching the front and rear horn is roughly equal in strength and if you are driving past a source it will only be very brief. Only situation where it might stay on a side arrow for a while us stopped at an intersection or in really slow traffic with a source to the side... In practicality not terribly useful.

I actually had a Ka signal that started out from the side yesterday! I was traveling 45 MPH I'd guess. That was a very rare experience!

Yeah, all they are are an indication that the arrows are switching directions and so they're not too big a deal.

I've seen people understandably focus on "side arrows mean the officer is to the side of you" and they go off about cosine error and how officers can't get your speed in that situation. While that is true, that's not really what the side arrows are for.

I guess it's like a traffic light switching from green to yellow to red. That yellow light is a brief heads up that the lights are in transition. Same thing with the side arrows.

I'm running an R7 and I do see the arrows transition from front, to side, to rear as I pass a radar source from the front, but the amount of time the side arrows are present is short (a few secs usually.)

I mainly want to know when I am past the threat that I cannot see, such as when a source is traveling toward me in the opposite lane and not necessarily visible to me. I get that information when the arrows flip from front to rear, so really don't need the transitional side arrows to give me that info. So, I as long as I see the flip, I'm satisfied

Wow, if those are the side arrows then i haven't noticed that little line as a side indicator. That's a terrible design.
I like the design since the side arrows are not nearly as useful as the front and rear, you really don't know what side it is most of the time anyhow - even with detectors with true side arrows. Its rare to see the side indicators light up for more than a few seconds most of the time.

In order for side arrows to be accurate you would need to stuff in two more horns into detectors and that would make the size and cost a bit prohibitive.

That does give me an idea however - It would be pretty cool to see a detector with a screen like the R7, with one arrow that always points to the source - Sort of like a compass for radar.

Since radar nor lidar can get you from the side, I really don't worry about it. Typically I'll see it when passing a false or even an LEO whos at an angle to my vehicle. Cosine error prevents them getting a valid reading.

As I understand it, the R7 displays the side-arrows when both the signals hitting the front sensor and signals hitting the rear sensor are of equivalent strength. So the R7 doesn't actually know that the signals are from the side (especially which side) but that both horns are receiving the same signal strength.

As for adding side-horns, the R7 is already pretty big IMO! :)

Maybe we will see people doing ghetto arrows for the side - One R7, Max360 or V1 facing forward and another facing the side. Someone will probably do it, just because they can.

I like the ability to display side radar signals however chosen to be displayed.
The most useful purpose of this I have experienced is getting a new radar hit while at cross roads, intersections etc, mainly while stopped.
This gives me a heads up to look for LEO to the sides before turning onto that street, or proceed through without doing anything to cause LEO to pay attention to me.
Had a few like this recently.
Front and rear arrows didn't come into play until I moved away from the side signal.
Helps to alert you that LEO could have eyes on you from the side.

JBV1 does that. :) For each alert; There's a little white arrow that shows the ratio of front to rear and there are graphs that show the level of both antennas as well as the frequency stability of each signal.

That would be a sight! I'm sure there's more than a few folks on this forum that have two of those RD's to give it a try.

I think there are issues with the two RD's interfering with each other unless they're kept a decent distance apart though.

In my past musings I've come to the conclusion that it could be done with 3 total horns. Front and rear of course, then a small horn or patch antenna on one side. If front and rear are nearly equal, then the presence of a signal on the side with the third antenna would be the source side. Else it's probably on the other side.

What about 4 detectors, without arrows, one for bow, stern, port and starboard.
A tinfoil divider can be installed in the interior isolating each detector cell from the other, eliminating interference.
Additional benefit would be 4 separate passenger private compartments, everyone will have privacy to text each other.
