Bank Bug Rock Steady Back Rest V2 explained 

This video from Bank Bug has a close up look at their Rock Steady Back Rest V2.
Angler's Mail tackle reviewer Richard Howard commented: "Bank Bug have listened to the feedback on their V1 ‘system’, spent 18 months field testing modified designs and have now launched the V2.
"You’ll now find a fully adjustable locking point incorporated into this system, and a super-strong O-ring with improved fitting.
"The locking boss is also longer, the locking point deeper and it’s an altogether tighter fit, to ensure it’s more rock steady.
"You can secure this system to any rod handle, anywhere along the rod butt, the idea being that it stays on your rod whilst you are playing a fish, without being a hindrance.
"But then after casting, it holds your rod solid, thanks to the Locking Point, which screws into any bankstick or buzzer bar. When you get a take, you can still strike cleanly as normal."
