Rob Allen has been using gun bungees for years and his are arguably the best in the game. Such a simple accessory can make such a difference to the ease of use.
Rather than using rubber which drills and tend to break down more quickly in UV, Rob used high elasticity HDPE material as it’s more UV stable and firm. Internally 800lb tested dyneema core material is used to ensure a solid connection between the gun and shooting line. With a large loop on one end and an oversize HD brass torpedo swivel with snap clip, ensures that no matter the fish, the gun bungee will not fail.
