My friend uses a quote that I applied to this idea, "work smarter not harder". I have been working as a Divemaster for a local dive shop for 3 years now and when we go to the pool I was making 2-3 trips to my truck to haul my gear in. I decided to "work smarter" and came up with this box that I can strap my tank to and haul everything in to the pool in one shot. Not much but I thought I'd share it.
