On page 72 BRB, first pic on the top-right, there is a "no man's land" or blind spot at the front and back of a Predator where neither of the two sponson mounted weapons can target a lone MC or IC. And I say this and not "unit" because units usually are broader and thus can at least fall into the LoS of one of the two sponsons most of the times. Either way, because the firing arc of the side sponsons is > 180°, their LoS eventually meet, at which point onward both weapons can target the IC/MC.

My question is, how far away from the Pred is this?

The pic on the bottom left of page 72 shows the LoS stretching a bit further, but they still havent met, and that distance already looks like 8" from the Predator's hull.

You need to physically look down the barrels of each weapon to figure that out.

There is no magic number that tells you this. A wide model such as a demon FMC would be easier for both weapons to target than a lone IC.

It depends on the target and how big that model is.

When targeting a single Space Marine the distance is quite far.

When targeting a single Trygon the distance is much, much closer.

Invest in laser pointers, they can help with LOS and figuring this out in general. Also your cat's will forever love (or hate) you.

Same with dogs. I've never seen a dog run in a circle for so long...

Well, there is a 'magic' number but its not going to look like a whole number and it will be written as an expression as it will contain 4 variables. You need to know the height of the target, the width of the target, the angle of the target to the front center point of the predator's and the length of the predator's gun barrel from its pivot point. That and a bunch of trigonometry will get you your real world minimum distance. Its probably just easier to squat down and take a look.

Not really, There are 7 magic numbers.

One for 28mm bases, one for 40mm bases, two Bike bases, one for Dread bases, and two for the oval bases.

You shoot to the base on non-vehicle models, so there is going to be a precise distance where the base is inside the arcs.

No, you shoot the arms, legs, head, or body of a model. You measure distance to the base. If the model has an arm that sticks out further than the base, it's going to have a wider profile that the vehicle can use for LOS.

If you cannot measure from the gun to the base, you cannot shoot at that arm either. It is the nature of the straight line/limited traverse from vehicle weapons.

I dusted off my high school trigonometry and tried to crunch some numbers. They seemed off, and when I went down for a gun's eye view, didn't match up. So I went for the practical approach. I leaned down at the edge of the table, with my eye right at the edge. I then slid my predator closer until I couldn't get a clear view on both barrels of the sponsons. This worked out to about 21cm from the front of the tank.

There is, as others have pointed out, a good number of variables involved in the kill zone for your sponsons.

The real question is, why have you let a Monsterous Creature get that close to your predator.

You don't need LOS to measure.

Using kels logic, vehicles can't shoot models behind an ADL because the base isn't visable...

Exactly.

That is not at all what I was saying.

What I am saying is that the base must be within the arc of fire; because vehicle weapons fire in straight lines and you have to measure from the gun to the base. if the base is outside of the arc, you cannot hit it.

Yea that's not true.

you measure to the base, but you shoot at the body arms legs etc.

If the arm of the model is wider than the base and you can see the arm you can shoot the model even if the base is outside of the weapons arc.

You measure to the base, but draw LOS to the body. There is nothing stating you are prohibited from measuring through the hull of the model, if required, in order to measure.

I love how these things come up again and again. We had the same thing about Storm raven sponsons and working out the minimum distance etc.

Fact is that these things only work on a flat game board with no terrain cover, the MC in a specific spot and don't take into account anything to do with the shape of the MC or the design of the turrets in this case. It's a waste of time and energy in comparison to just looking down the gun and seeing if it can hit or not.
