All the rubber came off the handles of my Nauticam Panasonic GH4 housing on my last trip, after 4 years. They're usable without the rubber, but I'd prefer to replace them. I also recall reading about a couple of cases where a Nauticam plastic handle completely snapped. I can certainly imagine happening when yanking one of my light arms around with a tight clamp.
I recall somewhere, probably Facebook, that somebody was making custom metal handles to replace the standard Nauticam handles. Anyone know anything about this? Or perhaps Nauticam have improved their handle design in the last 4 years?
