Hanger NASH Siren Night Glo Swing Arm

Product benefits

Designed for demanding carp anglers, the NASH Siren Night Glo Swing Arm is a high-performance illuminated bite indicator that pairs perfectly with Siren R4 bite alarms. Its articulated swing arm with adjustable tension and pulsed lighting synchronized with the alarm LEDs provides a clear view of every line movement, day or night.

The MMCX bayonet connection transmits the alarm's light signal to the indicator head. When the Night Glo function is activated on the alarm, the arm displays a discreet but highly visible pulsed halo with each LED trigger. You therefore get a coherent audible and visual alert—ideal for night fishing and crowded swims where bite readability is essential.

Advantages and product highlights

The main asset of the Night Glo Swing Arm is its ability to combine precise tension control with highly readable light signaling. The adjustment knob allows selection between operation based solely on pull-weight and three progressive spring-tension levels. This adjustment range makes it easy to fine-tune the setup according to conditions encountered: wind, current, slack line, very long-range fishing, or conversely short-range fishing near obstacles.

This system delivers an optimal reading of returns/drop-backs, often hard to interpret with an audio-only alarm. The arm returns to position under spring action, highlighting drop-backs while maintaining firm contact with the rig. The indicator thus works in concert with the Siren R4 alarm to provide clear information about what is happening at the bait.

The magnetic line clip ensures the line stays in the arm while the rod is down and releases cleanly at the moment of the hookset. Paired with the hockey-stick style magnetic mount, this system allows quick installation and removal without compromising stability. The pulsed lighting further improves user comfort by making even the smallest alert visible without dazzling or disturbing concealment at the swim.

Usage tips

To get the most out of your NASH illuminated bite indicator, first secure it firmly on your rod rest/support, then connect the cable to the dedicated output of the Siren R4 alarm using the push-and-twist connector. Ensure the alarm's Night Glo function is enabled to benefit from synchronized lighting. Next position the arm on the line, adjusting the height and leader length according to your rig.

Adjust the tension knob according to conditions: low tension suits bank fishing or calm conditions, while higher tension is recommended for long distances, strong winds, or cluttered areas. Make sure the clip is positioned so the line only releases when you take hold of the rod to strike. After each session, quickly clean the arm and indicator head to remove dust or moisture and preserve the reliability of the magnetic connection and line clip.

FAQ

Question 1 : Is this bite indicator reserved for Siren R4 alarms with the Night Glo function?

Answer: The Night Glo Swing Arm has been specially designed to connect to the dedicated output of Siren R4 alarms and synchronize its lighting with the alarm LEDs. It can operate as a conventional mechanical swing arm, but to fully benefit from the pulsed light signal, it is recommended to use it with a compatible alarm that features the Night Glo function.
