BCD's for dry suit diving should allow ____________ for the increased bulk of a dry suit.

For dry suit diving, it is essential that the buoyancy control device (BCD) allows for more adjustment to accommodate the increased bulk of the dry suit. When divers wear a dry suit, it adds additional layers and insulation that significantly change their body profile under water. This added bulk can affect buoyancy control and how divers manage their ascent and descent.

Having a BCD that allows for more adjustment means that the diver can fine-tune their buoyancy more effectively to balance the suit's effects, ensuring a more comfortable and safer diving experience. Adjustability in the BCD also helps fit the diver's unique body shape and the extra bulk of the dry suit, thereby improving overall stability and control during dives.

Understanding this need for more adjustment is crucial for dry suit divers, as it directly relates to safe and effective underwater navigation. Proper buoyancy control is vital for avoiding rapid ascents or descents, which can lead to decompression sickness or other diving hazards.
