## Description

【Measuring】Please measure the Outside diameter (including armouring) of the barrels to get accurate sizing, if the tubes outer diameter is between 51.8-53.3mm, it will fit perfect. If the diameter is different, please choose a different size. 【Fits Models】Fits most 42mm models including 8x42, 10x42 and 12x42. These covers also fit several binoculars / monoculars with objective lenses between 40-44mm as well as some scopes. 【Protection】These covers protect your lenses from rain, dust and scratches in any weather or environment. They also offer protection to your lenses in transit and storage. 【Easy to Remove / Add】Place the lens covers on the outside barrel of your binocular/monocular to protect your lenses. Covers remain attached to the binocular barrel and hang down when in use. 【Design】High quality flexible rubber is independently tethered and stretches for a tight fit. This ensures optimal protection for each lens.

Review: Perfect replacement for Nikon ProStaff7 loose caps - Ordered the 48.5-50mm for my Nikon PROSTAFF P7 10x42, and they are perfect! Work a treat! Much better than the loose caps provided. Perfect fit, hold well, easy and fast to pop open & close. Ideal!
Review: Excellent lens caps. - I bought these as spares as the ones on my binoculars have fell off a few times and I'm bound to loose them eventually, but I am now going to use these instead as they are a better fit with a tighter and wider strap that does not move on the barrels of my binocular. Good price, good quality.

## Questions & Answers

**Q: Hello! will the 42.6-43.6mm be compatible with ultravid 8x42 hd?**
A: Im not familiar with those particular bins but I'm guessing if they fit my 8x42 Nikon then they will suit.

**Q: Hi my binoculars seem to be 51.8mm so should I go for the 51.8-53.3 or the smaller 51.5-51.8mm?**
A: They will both fit perfect 
The internal diameter of the 51.8-53.3 is actually 51.3mm
The internal diameter of the  50.5-51.8mm is 50mm.

One will be slightly tighter than the other

**Q: Does anyone know if these would fit Celestron granite 10x42? Lost one cover and dont want to spend £20 replacing it!**
A: It should do, your binoculars are the same size.  I like them and would recommend them.

**Q: I have a Bushnell Falcon 133410 7x35 - i need replacement eye caps - which ones would i choose?**
A: Hi, Unfortunately i am not familiar with the specs of the Bushnell Falcon Binoculars.
Please measure the Outside diameter (including armouring) of the barrels to get accurate sizing, Please choose the lens cover with the internal diameter which matches your measurement
