For most recreational divers, the common high-pressure hose length of { 32 in | 81.3 cm } is long enough to be run under the left arm, across the chest and clipped off on the right shoulder D-ring. A few divers with a large chest, or who like to hold their instruments well out from their body when reading, require a longer hose length of { 42 in | 106.7 cm }. Some recreational divers seeking very streamlined configurations are routing their HP hose with a compact SPG over their left shoulder in the same manner they route their BC hose and those divers are using HP hose lengths as short as { 24 in | 61 cm } and even { 21 in | 53.3 cm }.

Technical divers almost always carry a standalone SPG clipped off to the left waist D-ring. For use with double cylinder configurations, the typical HP hose length is { 24 in | 61 cm }, although some divers find that length slightly too short. It's almost always too short when used with a single cylinder configuration. Many divers clipping to their waist D-ring find a HP hose length of { 26 in | 66 cm } to work well with both singles and doubles. Cave and wreck divers also remove the SPG boot for the same reason they remove the cylinder boot, because the boot surfaces have been known to ratchet divers into tight spots, making extraction difficult.
