SeaTouch 4 MAX PLUS filter kit
The 4 MAX PLUS housing with the red and magenta filters, the 67 mm clamp and a travel case. Not filters on their own.
Specifications
Read the name carefully, because the shop's own title does not make it obvious: this is the whole housing plus the filters, not a filter set to add to one you already own. If you have the housing, buy the filters separately instead.
What the kit adds to the bare housing is the part that actually decides whether the photos are worth keeping. Red light is gone by about 5 m (16 ft) and the rest of the warm end follows, which is why every unfiltered reef photo comes back blue. The red 67 mm filter puts it back in salt water, the magenta one does the same job in green fresh water, and the expansion clamp is what everything else you will eventually want, a light or a second arm, bolts onto.
The travel case is not nothing either. A housing, two filters and a clamp loose in a dive bag is how a membrane gets scratched.
