I was wondering if you had further info on the Vortex 2x Doubler for Vortex Binoculars, BAC-VT-2X; specifically:
Is it fully multicoated?
Does it have a Bak-4 prism?
Is it phase-coated?
Is it waterproof?
What are its dimensions?
Thanks for your inquiry. The Vortex 2x doubler is fully multicoated and waterproof.
It does not have any prisms in it, thus no phase correction needed.
The doubler weighs 3.5 oz, is 3" tall, and 1.75" in diameter at its widest point.
If you have any other questions, don't hesitate to email or call.
