Water in the BCD - causes, leak or more likely operator error.
Error 1: When decending once you have water over your head STOP dumping air! Your sinking, time to control the decent by adding small sprits of air every few feet to slowly float down. Often in newer divers we see then unconciously finnning (moving their legs back and forth) when they are trying to decend. This leads them to incorreclty beleive they need to dump more air to go down (no, just need to stop swimming up) and wind op adding water to the BCD.
Error 2: incorrect swiming position. Swimming in a head up manner so the body looks like / instead of -- in the water. Result of the angle is you are finning up and so you ascend without wanting to, think you need to dump air, stop swimming and dump air that you don't need to dump, but since you stopped swimming you sink and think that fixed it.
Tilting - causes, air bubble shift, loose BCD causing the tank to list to one side, inbalance in the weighting.
