Moose ears – XXL natural radar

Moose ears – XXL natural radar

It’s 5:23 a.m., light filters through the spruce trees. The scenery remains misty, almost fragile. You inhale: damp moss, crumpled bark. A clumsy step on the twigs; the creak explodes in your ears. Two hundred meters away, the moose hears it differently: for him, it’s an invitation. His two bells, as big as pie plates, pick up the slightest variation.

This is the superpower that turns a simple stalk into a thrilling encounter, if – and only if – you spread the right message, at the right time, with the right tools. We take the mechanics apart, then see how Recall Designs puts them to work for you.

1. Giant auricles: the decisive anatomy | Ears

1.1 XXL format

The auricles cover 2,800 mm², more than sixty times human size. Thirty muscles per ear. Free rotation: 180°. The animal sweeps the circle in less than two seconds, without moving the rest of the body.

1.2 Stereophonic hearing

Forty centimetres separate the two ears. This gap creates a natural stereo. Each horn measures the wave offset (< 0.001 s). The moose locates the source even before turning its head. Even better: the antlers reflect the bass, offering a gain of around 5 dB.

2. Field problem: the silent bull | Ears

A common scenario. A crack behind the curtain of fir trees. No growl in return. The bull advances, stealthy. Flaps tense. A poorly positioned or too loud call: he bolts. Your challenge: produce a credible signal, exactly in its frequency band.

3. Listening physiology: key figures | Ears

• Sensitive range: 20 Hz – 8 kHz. Peak: 100 – 300 Hz.
• Sweep: full circle in 2 sec.
• Directional filtering: -12 dB for the rear. Directs the call towards the target.
• Range: cow call heard at 3 km in zero wind; from 15 km/h, range drops.

4. Harness those senses with Recall Designs | Ears

4.1 RD-TRONICS: electronics that speak “foam

Encoded at 96 kHz, RD-TRONICS reproduces harmonics that are out of reach for humans, but clear for moose.

Fast mode :

1. Position the unit 30 m downwind.
2. Release three cow moans (8 sec). Pause: 2 min. Add a long moo (12 s).
3. Repeat every 20 min. Volume: 50%. Rises to 80% in dense.

4.2 Moose Break: the snapping cone

The Moose Break compresses the air. It boosts bass below 300 Hz. The result: a husky, irresistible timbre.

4.3 Rubbing palette: the language of wood

Russian cherry. Young male chik-chik on birch. Bursts of 15 s, every 5 min. Perfect for punctuating calls.

5. Case studies | Ears

“Two satellite dishes. First rubbing, he went for it!” – François

6. Weather and safety | Ears

• Light wind (< 8 km/h): low volume, long pauses.
• Light rain: low spans; 60% volume is sufficient.
• Dawn mist: raises the caller to avoid absorption.
• Safety: separate whistle after each sequence.

8. Checklist 30 s | Ears

• Wind and compass aligned?
• RD-TRONICS battery ≥ 80%?
• Dry palette, intact?
• Clear shot over 20 m?

FAQ – Moose hearing | Ears

Do moose ears surpass deer ears?
Yes: giant horn, better bass response. MFFP tests: +30% bass sensitivity.

How far does RD-TRONICS carry?
Up to 3 km in calm weather. Remains natural, adjusts volume.

Does the wind block the effect?
He scatters. Places the caller against the wind; sound travels to the animal.

Why combine Moose Break and palette?
Because the moose combines voice and wood. This duo creates a territorial response.

Does frequency change the reaction?
Yes. Peak response: 100 – 300 Hz, range amplified by Moose Break.

Do woods amplify sound?
Yes: ≈ 5 dB gain in bass thanks to reflection.

Does RD-TRONICS stand up to rain?
IP66. Humidity even helps propagation.

Frequency of sequences?
Every 20 min at dawn and dusk.

Is olfactory camouflage still necessary?
Always. Sounds and smells must be consistent.

Best period?
Peak rut: mid-September to early October.
