Most reef life barely registers red light, which makes this filter the quietest trick in your kit. Fitted for Bigblue's 1200-II series (2019), it lets you slide in close on octopus, shrimp, and night-hunting critters while they carry on naturally in front of your camera — and it preserves your night vision between shots.
Pairs well with: the SNOOT35 and FDK35 for the same 1200-II series lights.
