MEDICAL BRICK/Hazmat Exploration Rescue Sub
very good deep see sub that has a supposed crush depth of 100m BUT I FEEL like it will be much less due to how big the windows are.
when spawning in. quickly close the hatch behind you and LOCK IT. then lower the front left most lever. the emergency lift ALL THE WAY down. get into the helm and turn off bilge pumps and then go from there. have fun. spent several days working the issues out of this. this works very well in tight environments if you activate the front rudders and rear elevators. make sure its wired ONLY TO BALLAST breaker B
