A stable rod is the foundation of effective bite detection. At Gerry’s Fishing, we highly recommend the Preston Innovations Offbox Telescopic Feeder Arm for anglers who demand a rock-solid setup regardless of the terrain. Constructed from a lightweight but incredibly strong extrusion, this arm is designed to eliminate rod bounce and wobble, ensuring that every tremor and “pluck” at the hook is transmitted clearly to your quiver tip.
The hallmark of the Offbox system is its versatility. Featuring an adjustable angle tilt and a telescopic extending mechanism, you can position your rod tip with pinpoint accuracy—whether you need it high to keep line out of a river’s flow or low to the water on a windy day. The integrated SnapLok head is a standout feature, allowing you to switch between different rest heads in seconds to suit the specific requirements of your session.
| Feature | Specification |
| Material | Lightweight, high-strength aluminum extrusion |
| Mechanism | Telescopic extending with secure locking |
| Adjustment | Multi-positional angle tilt |
| Head System | SnapLok (Quick-release) |
| Compatibility | Fits most modern seatbox legs (Offbox 36 compatible) |
| Sizes Available | Short, Medium, and Long |
To ensure you have the perfect setup for your target water, the Offbox Telescopic Feeder Arm is available in three distinct sizes:
Short (45cm – 70cm): The ideal choice for commercial fisheries where you are using shorter rods (9ft – 11ft) and need a compact, maneuverable setup.
Medium (60cm – 101cm): The “all-rounder.” Perfect for standard lake work and most silverfish scenarios with 12ft rods.
Long (80cm – 137cm): Specifically designed for river fishing or large natural venues. The extra length allows you to push the rod tip high into the air to minimize the amount of line dragging in the current.
Ultra-Stable Design: The square-profile extrusion is significantly more rigid than traditional round arms, meaning your rod stays still even when you are moving around on your seatbox.
SnapLok Efficiency: No more unscrewing rest heads at the end of the day. One click and your rest head is detached, making packing away faster and protecting your gear from damage in transit.
Infinite Adjustability: The combination of the telescopic extension and the angle tilt means you can find the perfect “line” for your rod, keeping your tip exactly where the fish are most likely to trigger a bite.
Lightweight Portability: Despite its strength, the aluminum construction ensures your seatbox remains easy to carry to the most remote pegs.
The “Tension Lock” Secret: When extending the arm to its full length, especially on the “Long” version for river work, ensure the locking nuts are firm but not over-tightened. To achieve maximum stability in high winds, try to keep the telescopic section as retracted as possible; the more overlap there is between the two tubes, the stiffer the arm will be. For the ultimate setup, pair this with a Preston Dutch Master Feeder Rest for total rod security.
Does it fit 36mm seatbox legs?
Yes, the Offbox system is designed to be compatible with the industry-standard 36mm legs used on most modern seatboxes. It usually comes with inserts to fit 30mm and 25mm round legs as well as 23mm square legs.
Can I use this for heavy river feeders?
Absolutely. The “Long” version is engineered specifically for the rigors of river fishing where 4oz+ feeders and the pressure of the current put extra strain on the arm.
Will the angle tilt slip over time?
Preston’s locking mechanism is designed with a “toothed” or high-friction internal surface that bites into position when tightened, ensuring that once you set the angle, it stays there even under the pressure of a heavy take.
Is the SnapLok head compatible with other brands?
The SnapLok system uses a standard 3/8″ BSF thread, meaning you can attach almost any feeder rest head from any manufacturer to the SnapLok insert.
