Choosing the Best Regulator Hose LengthThe most common hose length found on the primary SCUBA regulator is about { 28 to 30 in | 71.1 to 76.2 cm }. For many divers, this hose is too long and will cause the hose to "bow out," and create unnecessary drag and tug on the mouth. This makes for an uncomfortable dive, particularly in current. Some divers choose the slightly shorter hose length of { 22 in | 55.9 cm }, feeling it is more comfortable with less drag and pull. However, most divers solve this problem with a very long primary hose, and use a { 22 in | 55.9 cm } hose for the backup regulator. This compact backup regulator is hung on a necklace directly below the chin. Many advanced divers and instructors believe the common hose lengths are too short in out-of-air situations and now use a much longer hose, often { 60 in | 152.4 cm } for those who dive open water exclusively. Technical divers have adopted a minimum length of { 84 in | 213.4 cm } for overhead environments, and in some exceptional circumstances even use a length of { 108 in | 274.3 cm }. The { 40 in | 101.6 cm } hose is the common choice for the alternate second stage used on most sport diving "octopus" regulator configurations. It is the recommended length for stage and deco regulators as well. The { 36 in | 91.4 cm } hose is a more manageable length for divers who carry small pony or "bailout" bottles for their personal use. |
