1.ConstantWeight The diver must dive and surface under his own power. The bodyweight of the diver must not be altered and needs to remain constant throughout the dive.
Constant Weight is an integral part of most competitions.
2. Variable Weight in this case the diver is allowed to use weights up to 35kg. The weight consisting of a diving sledge brings the diver down to great depths from which he re-surfaces under his own power. Either scaling the rope or using one's own fins is permissible. Variable Weight is not a competition in its own right, but world record lists are compiled.
3.Nolimits No Limits, as the name implies, encompasses no restrictions. The weight of the diving sledge is used to pull the diver into the deep. The diver is not subject to any weight restrictions. For returning the use of a lifting device which carries the diver to the surface is permissible. Here again, there are no competitions but only world record lists are kept.
4.Freeimmersion Free Immersion, similar to Constant Weight, allows no additional weights, but the use of the rope for diving down and back to the surface is permissible.
5. Static In the case of static diving the maximum time spent under water is recorded. The depth is of no account, only nose and mouth need to be submersed.
Static is an integral part of most competitions.
6. Dynamic The horizontal underwater-distance from A to B is measured. There are 2 versions: one with and one without fins.
Dynamic diving is often a part of pool competitions.
7. Constant Weight Without Fins The diver must dive and surface under his own power. The bodyweight of the diver must not be altered and needs to remain constant throughout the dive. The use of fins is not allowed. This discipline was introduced 01.01.2003 and thus there exist no lake records.
