When you shoot a 2k $ with a 1k scope , a $300.00 bipod ,it is not an issue to use a $120.00 bubble level.
Accuracy first in my book.

Buble level anti cant device

most of the extra little things that help the last bits of accuracy are expensive (unfortunately). The hawke bubble levels are to expensive in my opinion, 25 $/€ for something that starts to point upwards as soon as you tighten them (so basically useless IMO).
I use the Tier-One scope levellers to level my scope to my rail. After that I use a plumb-line to match the anti-cant device to my reticle. Now I'm just looking for a more decent anti-cant device.
That BFTA setup manual indeed is a very good guide for setting up your rifle.

The real question is how much does a degree or three of scope cant affect POI at less than 100yds?
Not much I imagine.

From 50 to 100 yards you will not hit the target in the same hole that is for sure without a level.
At 800-900 fps the canting results are more important than a caliber shooting at 2800 fps.
Ballistic coefficient involved.

At 100 meters canting my rifle from the bubble in the middle to touching the bubble to one of the lines gives me a deviation of about 2 to 3 centimeters.
The error increases with distance and lack of speed. The more your projectile is falling the worse the effect gets. A faster projectile will be effected less by cant than a slower projectile on the same distance.

Thank you for the detail.
So, who dont need an anti cant bubble level device for bench rest or hunting ?

I use a vortex scope level now and have noticed it has helped my accuracy at 50+ yards. The good thing about scope levels is that it doesn't matter if the level is super well made and precise as long as you set it to where your reticle is vertical when the bubble is centered. Just my opinion and why I wouldn't spend an awful lot of money on a scope level.

I have a SWFA SS bubble level. $19.99.
I mount it on the left side of a SWFA scope as far forward as I can. It takes a little work, but I can see the bubble level in my left eye, and the target through the scope in my right eye at the same time.

The most important thing is that you like what you buy. I personally don't mind spending a little more on something that helps my accuracy a lot. However, $100 on a bubble level is quit some money so I'm still doubting which one to buy.

I agree with you.
It also depend on your personal budget and your taste.
If soeone spend $2000.00 on a gun , $1000.00 on a scope, $350.00 on a bipod and so.
Why not spend $100.00 + on a level.

I think I have to correct myself on what enlargers the cant error: Of course more cant increases the error but also the height of the scope above the bore, higher gets worse. The distance also makes it worse. It is speed/BC independent since it is a fault caused by an angle from the original path which leads to basic geometry.
Thus short recap on what enlarges cant error:
Larger canting errors makes it worse
Longer distance makes it worse
Scope mounted higher above the bore makes it worse

"Scope mounted higher above the bore makes it worse"
Not true for gun cant.
Imagine that you had a gun with two scopes mounted on it. One scope is mounted 2" high and the other scope is mounted 6" high. Sight both scopes for 50 yards.
Rest the gun canted 15 degrees to the right, with crosshairs on target at 50 yards. It does not matter which scope you look through, both crosshairs are still on target.
The pellet will land to the right the same predictable amount, based on the trajectory and degree of cant. It does not matter which scope you are looking through.
Low scope or high scope, keep the bubble level.

An expert at what?
Scope height does not enter into the equation. It's strictly a function of pellet-drop and cant-angle.
horizontal shift = drop x sin(angle)
vertical shift = drop x (1-cos(angle))

I question this because the scope height have an impact at the target . No ?
If you use Chairgun app and change the scope height the results are different. No ?
Maybe I miss somethimg ?
