U-boat tiefenmesser

[Onkel Neal]

Always ask the experts: anyone have a picture of a U-boat tiefenmesser?

Do you know if there was an instruction on the depth gauge with
warnings or an instruction manual describing what depth was safe,
critical or dangerous?

I recall the main depth gauge has a yellow and red band to signify critical and dangerous.

yapp, this is the original old one from u995...nowadays theres another one in the boat. but this is, how they looked. no warnings, no instructions. i know about some others, with colored depth ranges. like the one, from das boot.
