What are the actual dimensions? I am looking for a case. Can you recommend a case that will fit these binoculars with flotation strap.

Expert Answer
A
Answered by Kurt Colbourne, Gear Expert, from IL, United States, on September 30, 2021

The dimensions of these binoculars are 7.2"L x 7.6"W. A case like this would fit the binoculars as well as having a little more space for accessories.
