Mounting an Instrument console on the end of the high-pressure hose is popular with sport divers because it puts all the information in one place along with freeing their forearms of additional equipment. Consoles are also frequently seen in classic octopus regulator configurations used for rental and training, making the job of the store equipment manager or instructor a little easier. Divers must always take care not to allow their console to "dangle" loose, creating an entanglement hazard plus not being environmentally friendly.
Instrument consoles are rarely seen in modern streamlined configurations used by experienced sport divers and never seen in technical diving configurations. Experienced divers are more concerned about depth, time and deco because often those are the limiting factors controlling their dive. They prefer to wrist mount their dive computer allowing easy access that promotes more frequent viewing of depth, time and decompression status. The diver typically stores their naked SPG out of the way on a shorter HP hose clipped to their waist D-ring in order to avoid dangling yet making the SPG easy to recover and read. Further, the compass usage techniques required for precise underwater navigation are easier with a wrist mount compass.
