After reading all the responses above, it would appear that water trapping requires a lot more work than predator/land trapping? Lots of equipment, gear and fastening systems. Just an observation.
For me, I would say it is the other way around. I dye and wax my water traps. Or footholds at least, I just dye conibears. That is it, no worries about scent control, just protecting traps and keeping them working fast and smooth. A drowning lock and short chain on beaver and otter footholds and a chain on bodygrips and small muskrat/mink footholds, factory chain that comes on the traps works fine for all of them. Gear and fastening systems, well I carry 11 (or 12, I think it depends on manufacturer what it is called) wire, a pair of pliers and an axe. Cut any stakes I need on site, wire traps off (I use the wire to make slide wire drowners, cut to whatever length fits the situation, on site for beaver and otter). Oh and hip boots, those are an iimportant piece of gear. Set traps bare handed, never worry about contimanated traps after a catch, or from them rolling around in the back of the truck with saw gas and bar oil, traps are set exposed, no need for freezeproof bedding material, etc.
I spend a heckuva lot more time on prep for my land trapping, and pack a lot more gear.
