What was the sea state? Also, for the last post, you state you ordered PD and it surfaced, dive and it hit the bottom. I never use the commands for depth changes. Once you become use to what it takes for the 'scope to breach the surface w/o surfacing, and performing a gradual dive, there's no need and you can be more precise with exact depth orders.
The ordered PD is 67 feet and the shallow dive is 147 feet. If you ordered a dive in shallow water...of course you'll hit the bottom.
