The Bushnell Marine model 137501 is a relatively inexpensive mid-size 7×50 marine binocular. They feature individual eye focus with a diopter scale on each eyepiece.
The scale is located on the bottom of the eyepieces in our preferred location for easy setting when in use. Index and scale marks are molded into the eyecups and housing to provide a long service life.
In this binocular review, I found the diopter scale to be inaccurate when compared to the correction numbers from my eyeglass prescription.
A smooth blue plastic armor provides protection over the entire housing. Our testers found this binocular sized and shaped to fit well when held for viewing.
Optical acuity of the Bushnell binoculars was generally good though we did notice some softness at the edges of the field of view.
With the soft eyecups rolled down we found little to no loss of field of view when viewing through eyeglasses. Loss of some field of view can be a problem on binoculars with limited eye relief.
The Bushnell binocular ships with a pair of front lens caps, an eyepiece cover, and a neck strap. The neck strap is thin and has no padding. A padded case is also supplied.
These Bushnell binoculars passed both our drop and dunk tests with no damage or issues noted.
Good optical performance and a low price coupled with a lifetime warranty makes these Bushnell binoculars a best buy.
