These things with their magnetic stock fitting are the most user friendly bipod system for hunters I've encountered.
Rob Gearing, the brains behind Spartan, came from the aircraft industry which is where he discovered the extremely strong Neodymium rare earth magnets. Having experienced the frustration we all have of carrying around a rifle with a bipod attached all the time - unbalancing the rifle, digging into your shoulder, getting caught in the bush etc - and knowing it's only going to be used extremely occasionally, Rob decided there You carry the extremely lightweight carbon fibre/alloy bipod out of the way in your pocket, in a pouch on your belt or in your daypack etc, and in seconds you can whip it out, whack it in the magnetic hole in the forend and you're in business.
