The interviewer says that it is interesting, and mentions that they had it in SHII.

Makes you wonder why then, with that info from a veteran of the U-Boat service, they still included it in SHIII ( and 4).

A U-boat POW of the time backs up Mr Oesten as well:

A reliable prisoner stated that he was acquainted with the Bathythermograph which bears the German nick-name of “Lachs” (literally “salmon”). As far as he knows this is never carried by U-boats on patrol but he thought that it was built into weather buoys. It might be carried by boats carrying meteorologists. If a boat remains submerged for a long time it is constantly to take samples of the water every half hour to determine the density. This might be done more frequently if the boat shows a tendency to rise or fall.
