Questions about this item:

jim L  hi , does anybody know what the - effective aperture---is for this binocular ? thanks jim
Andrew R  I'm not sure I understand your question. The magnifying power is either 20x or 40x depending on the installed eyepiece. The aperture is the objective lens(es) which is(are) 100mm. Exit pupil will depend on the eyepiece and will be either 5mm@20x or 2.5mm@40x.
sal t  Still completely unclear: DO THE BINOCS COME WITH EYEP PIECES OR NOT??????
Andrew R  The product overview specifically indicates the presence of "dual power interchangeable 20x and 40x eyepieces".
William D  Your description isn't clear, do these binoculars come with eye pieces?
Andrew R  From the product overview: "1-year Limited Warranty. Waterproof construction with a rigid all-metal body, dual power interchangeable 20x and 40x eyepieces."
