Measurement Instructions

The Aziak Equipment Bino Clamp is currently offered in 4 sizes, each size has some overlap to the size smaller and the size larger to allow some room for error when measuring your binos for sizing. If you do happen to fall between sizes, look at how your binos are tapered where you want the clamp to sit - choose the smaller or larger size based on where else you  may want the clamp to attach.

 

There are two methods for finding your size. If you have calipers, head to method 2, otherwise continue with method 1 below.  

METHOD 1

Step 1

To get started you will need:

- Binoculars

-Short section of dental floss or other small diameter string

-Ruler or tape measure

-Sharpie (Not required, but helpful)

Step 2

Choose where on your binos you want the clamp to sit. I recommend you place it as close to the center of gravity as possible - on most binos this is directly in front of the center pivot. (Except on open bridge binos, where you can put the clamp centered between the bridges). Wrap the small section of string tightly around the binoculars in the chosen location - you are trying to get the most accurate circumference measurement possible. Mark the location where the string completes one complete circle.

Step 3

Measure the length of the string with a ruler to within 1/16" to get the circumference of your binoculars. Compare with the sizing chart!

 SIZE     Smallest  Largest

 Size 1      5 11/16"     6  5/16"

 Size 2      6  3/16"     6 13/16"

 Size 3      6 11/16"     7  5/16"

 Size 4      7  3/16"     7 13/16"

METHOD 2

Step 1

using calipers, take two measurements of the diameter of your binoculars at the chosen location for the clamp - Not all binos are perfectly round (molded features in the rubber coating are common) so take an approximate average of these two measurements.  

Step 2

Compare the diameter measurements you took with the chart!

 SIZE     Smallest  Largest

 Size 1        1.810       2.010

 Size 2        1.970       2.160

 Size 3        2.130       2.320

 Size 4        2.280       2.470
