Has anyone experienced (or dived with) an SPG lens break at depth?
What happens and does the pin in the link act as a emergency shut off?
Thank you

the spg should be fine, the connection into the spg is severely flow restricted, and the spg is sealed internally.. no gas should get to the lens side..

I have cracked and/or flooded several guages but its usually on very deep dives.. the shallowest I have evr cracked one was about 400fsw
