12oz difference your Zeiss Conquest are smaller so by nature they would weigh less
I guess since the Geovids have more capabilities they would weigh a bit more but comparable to the same...31oz for what they are is great--trust me you will love them, get you a good bino harness and you won't notice the difference.
Pentax 10x42 25.8oz (non range finder bions)
ATN Omega Binocular 10 X 42RF 36.0oz (non range finder bions)
Zeiss Victory 10x45 T* RF Rangefinding Binoculars 35oz
Burris 300282 10x50mm 27oz
Brunton 10.5X43 Epoch Full-Size Binoculars 25oz, i had a pair of these and thought they were heavier than my geovids.
ya got to compare apples to apples not apples to oranges.
