Differences between Redline and STi Driver?

[sx4dude2013]

Could anybody please tell me the differences between the two detectors?
Is one "better" than the other?

The Redline is "better" than the Sti.

Though both being based on the M3 platform, the Redline is essentially a "tweaked/revised" Sti (as it is 2+ years newer), so it will perform slightly better than the Sti in most all cases.

It isn't much... but if you're spending over $450 anyways on an RD... you might as well put the extra $30 on to jump from an Sti>Redline.

Sti sucks for off-axis detection

but sti has better ramp up..

The sti's male and the redline is a female

Most of the video I seen the Redline pick up first.
