Black frost bite indicator with black cord and a 90 Degree Jack Plug.

The Stem Tackle Black Frost Illuminated Bite Indicator is a high‑quality, hand‑made bobbin designed for carp anglers who demand reliability and clarity in all conditions.

The frosted Black bobbin head diffuses light beautifully, allowing the ultra‑bright LED to illuminate in Red, White, Blue, Green or Purple, giving you clear visibility whether you’re fishing during the day, at night or in low‑light situations.

Each bobbin is built around a metal‑reinforced under‑section, adding strength exactly where it matters most. This is paired with a durable, flexible para‑cord, creating a dependable connection that resists tangles, knocks, and long‑term wear.

The 90 degree 2.5mm jack plug is designed for alarms with power outputs located on the rear or side of the alarm, ensuring a clean, secure fit.

They are also specifically sized to fit in the recess in Fox and Wolf alarms, while still being compatible with all other alarms that use 2.5mm jack plugs. (Excluding Delkim).

Strong, bright, and engineered for real‑world angling — the Black Frost bobbin is a dependable part of any modern carp setup.
