With every bite alarm you will receive two pairs of snag bars (a short and a long set) that can be screwed into your bite alarm. The bite alarms have an adjustable volume and tone and are also waterproof. They have a maximum wireless range of 200 meters and both sets feature the Rolling Code System which prevents interference between wireless bite alarm sets. The set with 3 wireless bite alarms comes with a practical storage box. Perfect for carp fishing and dead-bait fishing!
