Some oversea divers can hold breath for amazing 10 minutes. Dynamic [with/no Fins] Dynamic with/no Fins is to compete the underwater swimming distance while holding breath. For this competition, the diver can chose whether to use fins or no fins. <Petersen DYN200m> Constant weight[with/no Fins] This competition is to dive vertically while holding breath and compete the diving depth. For this competition, the diver can choose whether to use fins or no fins. This is know as most popular freediving competition. The diver is not allowed to change the diving weight. <Shun CWT 81m> Free Immersion This competition is similar to Constant Weight in terms of competing the diving 'depth' while holding breath. The difference is Free Immersion uses the vertical guiderope to pull him or herself down to depth without fins. Variable weight This competition is similar to Constant Weight in terms of competing the diving 'depth' while holding breath. However, the diver is allowed to change the diving weight. Many divers takes advantage to dive deep sea to the bottom with heavy weight and less swimming then return to the surface without diving weights. Patrick Musimu VIDEO 120m No limits This competition is similar to Constant Weight and Variable in terms of competing the diving 'depth' while holding breath. This competition allows to change diving weight, and also allowed to return to the surface using inflatable bag. This competition uses least oxygen among all diving depth competition.
