| Basically Static Diving is where the boat contains some form of ballast tank/tanks. These can be filled with water, to cause the boat to submerge, or "pumped out" , for resurfacing. There are various methods of controlling the water levels, e.g. pumps, gas/air pressure systems, etc. This method can be used to control the dive/surfacing of the submarine even when not moving forward, hence the term Static Diving.
This method of control is more akin to full size practice, and lends itself to very sophisticated forms of automatic trim and depth controls, at a price of course, as per the original comments
With Dynamic Diving on the other hand it is a more simplified method of control, where the model is ballasted to a point of neutral bouyancy, then the use of the dive planes during forward motion will cause the model to dive and resurface as required. Similar to elevator control in an aircraft model. This method will only work during forward motion of the model, and stopping will cause it to resurface, regardless of dive plane control.
I hope this gives some insight into the basic differences of the two systems.
