The waterproof and fogproof Gray body is 159mm (6.25 in) long and 1,049 g (37 oz), runs a CR2, focuses to approximately 4 m and carries a built-in 1\/4-20 rotatable tripod adapter, worth using at this magnification.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe BX-4 Range HD Gen 2 TBR\/W 12x50 is the long-reach rangefinding binocular in the BX-4 line.
