## 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
