Frequently Asked Questions
Which BX-5 Santiam should I choose?
The 10x42 is the best all-around carry size. The 12x50 adds detail and brightness for glassing distant terrain. The 15x56 is a tripod binocular for picking apart big country.
Do I need a tripod for the 15x56?
At 15x, hand-holding makes the image shake, so a tripod and binocular adapter are recommended for long glassing sessions.
How heavy are they?
About 24 oz for the 10x42, 32 oz for the 12x50 and 45 oz for the 15x56.
