Could someone please help me understand where to mount the canister and how you would route the cable for use with side mount. Im right handed so I would imagine the light head would be on my right hand? I tend to use my left hand for LPI and drysuit inflation and right hand for bcd dump valve (BCD is SMS 75) as the pull cord is on my left shoulder, I think I could reroute it to my right shoulder so everything in left hand accessible. A photo or video would be awesome.
