Well, I did FotRSU first, and the results are in:
My Tench did not have FM sonar though, even on April 15, 1945 at about 1800 by the time I got up there, but there was the minefield... and yes, for you US citizens, that is a slight dig at the date...
My pictures through the periscope did not turn out too well, but here's a few others:
A mine, as seen from the external camera from underwater.
Same mine from the surface up close
That's my sub at the bottom, and a bunch of little white orbs out in front of the sub, sitting at PD. You can see the first mine about 1/3 of the way down from the top edge. My sub's bow is about 1/3 of the way from the bottom edge.
Blowing up a mine with the 40mm AA gun. That bright "gold" color on the targeting reticle is just the sun setting behind my location.
Thus far, the procedure to follow with a Tench is the same as it is for the S-18 = "Go and be careful", aka: "Go around it"
