I am a big fan of the RTS setter. Here are the advantages that I can think of:
- super easy to use with only one hand needed - get yourself caught and you may find this to be a lifesaver (yes a rope can work also, but I like a single tool that does it all)
- always locked unless you press the unlock tab
- can be used as a safety
- on big dangerous BGs like sauvageau and MB1216’s I first compress and hook the spring safeties, then use the setter to open the trap and it is held safely open all the way until I put my bobby-pin safety on
- I often use it to hook a body grip and pull it up when retrieving an animal or fired or even a set trap - it acts as a sort of general purpose “gaff” to pull anything up out of deep water
- one of my favorite “off label” uses is for dragging big beavers. Just clamp the jaws onto a front foot and you have a nice comfortable handle to drag even the biggest beavers, and it is just the right length to keep the beaver partially lifted, which makes dragging over obstacles easier
It does have one disadvantage - cost. But I have been using mine for almost a decade now so that cost comes out to about $5 per year and going down every year I use it. As much as I like it and use it daily, the extra cost is a no-brainer. If I am running BGs I wont leave the truck without it. One of those game changing tools in my opinion. I used to carry a set of scissor type setters for a backup, now I have a second RTS setter for backup.
