With 10x optical zoom for outstanding clarity at distance, the Optics Monocular 10×42 is a vital piece of equipment when it comes to watercraft and observing your quarry. The 42mm diameter multi-coated lens allow light to flood into the eyepiece to offer a greater field of vision, which is especially useful in times of low light, such as dawn or dusk when fish can be at their most active. They feature a solid frame with a textured rubber finish for a reassuring grip. A large rubber focussing wheel, makes it easy to adjust for pin-sharp focus from distances of 2.5m to as far as the eye can see. The waterproof, nitrogen-filled chamber ensures zero fogging for perfect clarity. Weighing in at a mere 324g, this compact lightweight Monocular allows extensive use without fatigue. It comes complete with carrybag, wrist strap and lens cloth.
