John,
The dot dissapears when the power is off, it just becomes a regular duplex. The light turns on by pressing a scope cap where the side focus would be on a LR Leupold.Tthere are five levels of brightness that scale up with each push of the switch. Hold it down for three seconds and it goes off, or if the rifle doesnt move it will go off in five minutes, and back on if you move the rifle.
On level five you can easily see the dot in bright sunlight.
Don't know if the glass is the same as the VX3, but seems as good to my tired eyes.
