RE: WILL LASER TARGETING EFFECT DBU
In theory, maybe. If the laser hits the DBU/TBU directly, enough visible light might leak through to skew the gain circuitry in the sensor if it has any sensitivity in that range. And of course, infra-red is on the red end of the spectrum.
But, that said, laser's have a very narrow range of emitted light and it would be focused around the visible wavelength, so it's also quite possible that it would have no effect.
