WEST MARINE

COASTAL 400

MODEL 18407650

Adjusting the internal focus is smooth and easy keeping the right eye closed. Adjust for eye strength next with only the right eye open by twisting the eyepiece. The binoculars are light, partly due to the absence of a compass. The neck strap snaps on and off easily, and the objective lens covers flip down and out of the way. The eyepiece covers hang from the neck strap.

IN THE BOX: The ballistic nylon carry case includes a padded neck strap and lens caps and a lens cleaning cloth. CONCLUSIONS: These let us read the chart at line 8, second from the bottom, in both dim and moderate light. They excelled in sunlight but, as expected, weren’t as bright as the pricier models. In our 100yard test they could read line 6, fourth from the bottom, consistently. We prefer their internal focus to separately focused oculars because changes from one range to another were quick, as tested by switching from 25- to 12-yard targets.
