It really is a great improvement. I spend most of my time either on the bridge, at the map, or in the conning tower, so it's great to be able to move around in the tower. I know the 600' gauge is supposed to be for aethestic purposes only, but I was happily surprised to see that the gauge actually tells the correct depth--I had assumed that the gauge would read 600, but really mean 450, for example. In other words, I'm another satisfied customter.
I especially like looking over the shoulder of my diligent radar operator now
