Me & my wife use lanyard similar to the one in the link.
Hers was for a compact Ikelite housing for Canon S100, tray, arm and one medium size light.
Mine was for Ikelite Housing for EM5III, tray, arm and one Ikelite DS-161 strobe.
Look for landyard that there's stainless steel cable core inside the coiled spring part.
First couple of set that I used did not have the core, and it disintegrated during storage.
For entry, it depends on situation. If it was calm enough, we'll have the camera handed to us after our entry. However, sometime we giant-stride off the back of a boat in flowing current. So, we hooked the lanyard to D-ring on BCD, unlock the buckle, lift the camera set overhead and big step giant-stride off the boat. Doing this properly the camera won't get any impact at all.
