In theory this is what you want. For day you need green, period. For night green not only totally gives away your position but because it reflects off the tiniest particles in the air it is distracting to the shooter. So you need red at night, period. The problem is both the green and red on this unit lack the intensity for either job.
Pros: Red and Green together at last
Cons: intensity is weak
