That was my post:
View attachment 189325 My wife and I use them for all shore diving not from a dock. Highly recommended as a cane adds a third leg of stability. My wife's cane is collapsible aluminum, having a bungee cord down the middle, and is stored in a home-made nylon holster attached top and bottom to her BC. I started with the same, but switched recently to a non-collapsible stainless steel version that can bear a 500 lb load. My legs are unstable and I caught myself recently mid-fall in a manner that snapped off the handle (from which I infer that some canes are meant more for balance maintenance than stopping falls). Hence, an overall stronger product was desired. My cane is not collapsible and I must pass it to my wife after entering and she attaches it to my tank, underneath the velcro end of the tank strap and with a loop of bungee attached to the cane that goes around the lower end of the tank. Not as tidy as the holster and collapsible cane, but it works. The process is reversed upon return. Frankly, I think a cane can be considered a mandatory piece of shore diving equipment for many of us of a certain age and disability level.
