Waterproof (30 minutes at 1M depth) and nitrogen filled for clear, fog-free operation. Twist-up, 3–position eyecups with metal sub-structure. Suitable for spectacle wearers. Knurled metal, easy-grip 2-turn focusing knob. Integral tripod bush. Supplied with neck strap, eyepiece rainguard, objective lens caps and soft case.
