For the most accurate shot, a gun rest is a great help, and Vanguard have been producing supports since 1986.  Here you can see an overview of the Vanguard range. This includes:

Rifle Bipods:

Clamping Gun Rests:

Stalking Gun Rests:

Other Gun Rests & Accessories:

EQ-Precision Bipods are lightweight carbon fibre bipods topped with a ball joint that can rotate ±360° and tilt ±35° (which can als reduce the height of the bipod in use) and then lock firmly in place for maximum accuracy on any terrain. These include options that use a quick release system that works with Arca rail fittings or Picatinny rail fittings to remove the bipod when not needed, or swap between rifles. In case your rifle does not have an Arca or Picatinny rail system, each bipod includes an appropriate Endeavor Sling Stud Adaptor that attaches to your front sling stud. The series is also available in two sizes. Best for target shooters and long range shots.

Equalizer Bipods are lightweight aluminium and carbon fibre pivoting bipods topped with a helical buffer spring that rotates ±35° and tilts ±10° to allow you to adjust your aim in the field. These include options that are designed to stay attached to your rifle sling stud, or uses a quick release system that works with Picatinny rail fittings to remove the bipod when not needed, or swap between rifles. In case your rifle does not have a Picatinny rail system, each bipod includes an Endeavor Sling Stud Picatinny Rail Adaptor that attaches to your front sling stud. The series is also available in two sizes. Best for hunting when need to track a moving target.

The demo video below helps explain the differences.

The Endeavor RL Series includes a solid tripod base topped with a removable half bowl levelling system that has an intuitive handle below to control a ±15° vertical movement and 360° panning movement, but can be locked into position or the tension adjusted for your shot.  

Fitted to the top is an Endeavor GM-70 rifle clamp, or a built in 2-in-1 clamp that can fit both an Arca compatible base and a Picatinny Rail.  The Endeavor GM-70 can lock to the rifle forestocks from 30mm to 70mm wide, with a moulded rubber inner lining to protect the rifle in use and an oversized locking knob that makes it easy to use, even in conditions that need gloves.  Capable of holding any rifle up to 15kg with ease, and extending up to 1,730mm, this series of gun rests is a great solution for the shooter who needs maximum stability.

The Quest Series is a traditional range of lightweight and portable gun rests with a 20mm leg diameter, with the Quest T62U as the most versatile of all the models (it can be set up as a tripod, bipod or monopod) still weighing just 1,000g while extending to 1,575mm.  All the models feature a wide, open U-Yoke (that is also available separately) that is great for rifles, shotguns or air rifles and rotates 360°, with rubber fins to protect the forestock of your rifle.

The Scout T62 A is great value aluminium tripod gun rests for those who want to save a little money, or try out a gun rest for the first time.

These are a little lighter than the Quest Series with four leg sections and a simple V-Yoke that rotates 360°.
