I don't put anything on my wrists, or ankles for that matter. If you put it on, you have to take it off and sometimes you can forget to take it with you when you leave the boat or shore...So, I cut a piece of 2" thin-wall (schedule 20) PVC pipe, drilled a hole in each end and covered it with some neoprene. I strap the Backup Compass, depth gauge, bottom timer and Dive Computer around the pipe until it compresses the neoprene and clip the pressure gauge on the left side. I sling this across my chest with surgical tubing and a suicide clip to the "D" ring. I can see all the "machinery" in any position and when I exit the water, it is just a matter un-clipping the right side and removing the harness. Everything is all in one place. I run a bungee though all the straps and tie it off through the PVC pipe. The pipe provides a great place to keep your gloves and snorkel inside and a knife strapped to the outside. When I pack or store it, with all the gear still attached, I put it in a padded bag.
