No — each alarm unit requires 2 × AAA batteries, and the wireless receiver requires 4 × AAA. Standard alkaline batteries work perfectly. For overnight sessions, we recommend Duracell or Energizer — or rechargeable AAAs with a USB charger.

Up to 100m (330ft) in open line-of-sight conditions. In a typical bankside swim with vegetation, expect reliable range of 40–70m — more than enough to cover your bivvy. The receiver gives you a specific channel alert so you know exactly which rod has a run.

Each alarm has an independent sensitivity dial — turn it down in windy or flowing water conditions to eliminate false bleeps. In calm still water, maximum sensitivity gives you the fastest detection. Fine-tuning takes about 2 minutes per session to dial in perfectly.

Yes — the S9 alarms are IPX4 rated, meaning they handle splashing and rain from any direction. They have been tested in heavy sustained rain. They are not designed for submersion. The receiver should be kept sheltered inside your bivvy.

The clip mechanism is adjustable and fits standard bank sticks and rod pod front rests from 8mm to 16mm diameter. Compatible with Fox, Korda, Daiwa, Nash, and most universal pod systems. No adapter needed for standard setups.

The 3-Alarm Set includes 3 bite alarms + 1 wireless receiver — ideal for a standard 3-rod carp setup. The 4-Alarm Set includes 4 bite alarms + 1 receiver — perfect for a 4-rod river or multi-rod session. Both use the same receiver and are fully compatible with each other.
