A cheap personal trick useful making for long time snorkling movie at 2.5m deep !

@Sam Miller III,
Thanks for your kind comments and suggestions !
With the actual design I get rid of most lateral (the pizza pan) and tilt (long tube filled with water) high frequency movements I had before.
But if there are waves and currents I am tossed both about and up and down ! For this I don't see any cheap solution except waiting for better conditions !
The problem in Elat, at least near Coral beach or the Egyptian border where are located the 'Caves' is that the northern wind is blowing ~ 10 mph most of the year bringing ~ 1 foot waves ! I live in Jerusalem and I look everyday at the weather report hoping for a few days break ! I guess I will be lucky some day ...

A rather cheap 5m waterproof multi-axis gimbal usable in salt water and compatible with the Dual Hero System would be nice but I have not seen any ... Everything I have seen on the Internet are splash-proof or sweet water gimbals.

To reduce movement may I suggest that you fashion small wings to the submerged camera. Only trial and error will determine the shape and size of the wings

Samuel, our divers used such way many years ago
Even mass produced camera boxes has it, e.g.:

(underwater housing ПКБ-2 for film camera "Sport")

or we had selfmade models

We call this devices - Aquaplane.
It is the same as airplane tail

SWeiller, This can allow you to stabilize camera and prevent unwanted movements.

@ АлександрД,
Thanks for you message and pictures !
Will study if there is a simple possibility to add a wing to the Dual Hero System !
