NorBruin Bear Horn electronic whistle — Rechargeable 128 dB SOS horn with USB-C, battery display (black)

The NORBRUIN Bear Horn is a rechargeable electronic whistle that emits up to 128 dB of high-frequency sound and includes SOS mode and a battery display for reliable outdoor signaling.

Compact and purpose-built for hikers, campers, and travelers, this electronic horn replaces forced-air whistles with a hygienic, push-button alarm. It generates focused high-frequency tones designed to attract attention and deter wildlife, while offering a USB-C rechargeable battery, a visual charge level indicator, and a protective housing suited to rough outdoor use.

How loud is the NORBRUIN Bear Horn and what frequencies does it use?

The device produces two selectable volumes: a high setting that reaches up to 128 dB and a lower setting around 120 dB. Its output emphasizes the 18–20 kHz high-frequency range, intended to cut through ambient noise for both human listeners and wildlife alerts.

• High mode: up to 128 dB for maximum attention in noisy environments.
• Low mode: roughly 120 dB to conserve battery while still signaling effectively.
• High-frequency emphasis: 18–20 kHz range to produce a sharp, attention-grabbing tone.

What signaling options and battery feedback does it provide?

Alongside instant push-button activation for continuous tones, the horn includes an automatic SOS pattern: three short, three long, three short signals that repeat with brief pauses. Four blue LEDs display remaining battery charge and charging status so you can verify readiness before heading out.

• SOS mode cycles automatically to sustain attention without constant user input.
• One-button operation for fast, intuitive use in stressful situations.
• Four-LED battery indicator and USB-C charging for modern convenience.

How durable and weather-ready is the unit for outdoor use?

The NORBRUIN horn uses a rigid ABS housing to resist impacts and everyday wear, paired with a silicone cover protecting the USB-C port from dust and light splashes. A sturdy backpack clip keeps the alarm accessible and reduces the chance of loss when on the move.

• ABS full-body construction for drop- and scratch-resistance.
• Silicone port cover to limit debris and moisture exposure.
• Included clip for secure mounting to packs, belts, or gear loops.

Is the device hygienic and easy to operate during emergencies?

Because it is electronic, the NORBRUIN horn removes the need for mouth contact and strong breath, making it cleaner and easier to use than traditional whistles. Quick single-button activation and clear mode options are designed for fast responses under stress.

• No blowing required: reduces contamination risk and simplifies use.
• Immediate sound output with no special technique needed.
• Two volume levels help adapt to different situations without delay.

Who is this for: The NORBRUIN Bear Horn suits solo hikers, group leaders, outdoor guides, campers, and travelers who want a dependable signaling tool that’s reusable and easy to check before departure. It’s useful where loud attention signals are needed — for wildlife deterrence, group location, roadside emergencies, or as part of a compact safety kit. Backed by a two-year support promise, it’s a practical addition for anyone prioritizing accessible, hygienic, and rechargeable emergency signaling on outdoor adventures.
