Modular Red Filter

€39 Inc. VAT

Attached to the CRUIT the red filter KNOCKBOY prevents the fish to swim away so you can focus before you take your photo’s.


The Modular red filter got its name from the Yellow Mountain or Knockboy (Irish: An Cnoc Buí, meaning “Yellow Mountain”). Knockboy is a 706-metre-high mountain on the border between counties Cork and Kerry in Ireland.

It is the highest peak in the Shehy mountain range and the highest mountain in County Cork with its summit shared with County Kerry. It is said to be the 104th highest peak in Ireland.

More details

  • The ERRIGAL is fully modular with all Anchor Dive Lights and can also be used to mount small compact cameras and GoPro’s.
  • The height of the grip can be adjusted to fit different hand sizes – 35 mm – 50 mm.
  • The light adapters or camera mounts can be easily mounted due to the extra mounting points in the handle.
  • Errigal is prepared with various slots and holes for mounting.
  • There is an additional 2 x 8mm threaded holes to mount 8mm threaded ball adapters should the diver need to move the light away from the camera lens. However, when doing this we recommend to purchase a tray with 2 handles for additional stability to reduce camera shake.
  • The goodman handle ERRIGAL can be used in combination with all our light. GoPro and other action Cameras can also be mounted when using the correct adapter.
  • While the molded aluminium does cost more to produce the results are that the ERRIGAL is very hard wearing thus is much better wearing than other shaped and welded versions.
