Frequently Asked Questions

How do I know if I need to replace my sphere?
+

Common signs include visible scratches, chips, crazing (fine surface cracking), or cloudiness that affects image sharpness. Minor surface marks can sometimes be polished out, but deep scratches or cracks that show up in photos are best fixed with a replacement sphere.

Is the spare sphere compatible with my dome port?
+

This {4" / 6" / 8"} sphere is designed for {specific ports / all Meikon, Sea Frogs and Salted Line {6" / 8"} acrylic dome ports}. If you're unsure whether your port is compatible, contact us with your dome port model or SKU and we'll confirm.

Do I need any tools to replace the sphere?
+

No special tools required. The sphere is designed for a straightforward swap — unscrew or unclip the old sphere, seat the new one, and reassemble. Refer to your dome port's documentation for the exact steps.

Is the replacement sphere the same optical quality as the original?
+

Yes. It uses the same optical-correct acrylic as the original sphere supplied with your dome port, so image quality, sharpness and colour transmission are identical.

Will this sphere fit a glass dome port?
+

No. This is an acrylic sphere and is only compatible with acrylic dome ports of the matching diameter. Glass dome ports use a different construction and are not interchangeable.

Q: Can I use this sphere as a spare to take on a dive trip?
+

A: Absolutely — keeping a spare sphere in your dive kit is a great idea, especially on liveaboards or remote locations where replacements aren't available.
