Amplify your hunting with RD-TRONICS

Amplify your hunting with RD-TRONICS

To understand a moose, you must first grasp what it hears. And what it hears, it amplifies. Thanks to its antlers.

These large bony surfaces are more than just ornamental. They act as natural parabolas. They concentrate sound. They amplify them. Precisely the ones that count: female calls. A study by the Bubeniks (George and Peter) shows that these antlers increase sound pressure by around 19%.

This changes everything. Especially if you use RD-TRONICS.

Combine this knowledge with a well-planned call sequence at dawn or dusk, and you go from simple call to irresistible signal. This text shows you how. With what. And, above all, why it works.

Moose antlers: amplifiers, reflectors, sensors | Amplify your hunt

The male doesn’t listen like we do.
He picks up what his female is saying, even from a distance. Thanks to his antlers.

These palm-shaped woods form a concave structure. They reflect sound back to the ears. They work like satellite dishes. Better still, they filter. They prioritize low frequencies, between 150 and 400 Hz, where the moans and long complaints of a cow in heat are to be found.

Three principles come into play:

  • Concavity: the shape picks up and redirects.
  • Surface: the larger the surface, the more powerful the effect.
  • Material: dense bone reflects sound without absorption.

Result: a bull hears better than you think. And if he hears you, he reacts.

Why the parabola effect increases your chances | Amplify your hunt

Imagine a moan. Whispered at 600 meters. Received as a normal voice at 500 meters.

This is the first effect: reach.

But there’s more. The bull uses his antlers to locate. He turns his head. He analyzes. He targets. He moves towards what he hears. This is what we call the directional effect. And when he’s sure of the source, he moves forward without hesitation. No visuals required. He’s confident.

That’s exactly what you need to create. A credible signal. Amplified. Captured. Interpreted as real.

RD-TRONICS + moose antlers: a natural duo | Amplify your hunt

Your RD-TRONICS is not just a loudspeaker.
It’s a generator of optimized acoustic sequences.

Its conical driver respects low frequencies. It follows the same profile as the bull’s antlers. The sounds it produces are captured and interpreted as authentic.

Add a Moose Break. Moan gently, with control. Complete with the rubbing paddle. Break branches. Imitate a nervous rival. You now have three layers of sound. Three credible signals. And a bull who, if he’s around, will come and check.

Recommended times and sequences | Amplify your hunt

Inspired by observations published by Field & Stream, here’s a field-tested sequence.
It respects the peaks of activity linked to light and the rutting hormonal cycle.

Time Volume Call type Pause Desired effect
05 h 15 Low Long complaint 5 min Alarm clock, sound test
05 h 30 Medium Short bleat 4 min Gradual awakening
06 h 00 Fort 3 male grunts 8 min Targeted provocation
12 h 15 Very low 1 moan 15 min Passive monitoring
17 h 45 Medium-strong Cow + grunts 6 min Contact simulation
18 h 30 Fort Breaking branches 10 min Physical presence
19 h 05 Medium 2 complaints 0 min Strategic withdrawal

Field tip: the RD-TRONICS does not have an automatic crescendo mode.
However, it does allow you to import your own sounds via its mobile app.
So you can create a complete sequence with volume variation, as if a moose were gradually increasing in intensity. This customization becomes a real advantage in the field.

What the data says | Amplify your hunt

  • 119% sound pressure measured at the center of a web (anechoic chamber tests)
  • 87% of approaches to the Yukon took place between 05:00 and 07:00 or 17:00 and 19:00 (source: MFFP)
  • Sounds between 180 and 280 Hz trigger an approach in less than 3 minutes in dominant males (University of Alberta, 2023)

In the field: optimal implementation | Amplify your hunt

Position the loudspeaker in front of you, with your back to a spruce curtain. The sound will bounce off it naturally.
Watch the wind. Less than 10 km/h, sideways, never backwards.
Watch the humidity. After rain, bass resonates better.
Position yourself at a 120° angle, so you can see without being seen. Never stand behind your caller.

Testimonials from the field | Amplify your hunt

“At 05:15, I triggered the RD-TRONICS. At 06:08, a big 52-inch arrives, straight ahead, ears turned. Zero hesitation. It was surgical.” – Martin G., Témiscamingue

“With the Moose Break and the paddle, I’ve doubled my chances. The bulls listen. The wood does the rest. It’s become a science.” – Julie R., Restigouche

Conclusion: plan, program, harvest | Amplify your hunt

It’s not just a gadget.
It’s biology applied to hunting.

Wood amplifies. RD-TRONICS reproduces. The combination of the two multiplies your chances.

Add the Moose Break voice. The realism of the palette. And you orchestrate the perfect illusion.

FAQ – wood amplifiers moose and calls | Amplify your hunt

Do moose antler amplifiers work in closed forests?
Yes. Density reduces the range, but woods still pick up direct sound up to 400 meters away.

Why choose RD-TRONICS instead of a simple horn?
For consistent volume and respect for frequencies. Two essential elements for getting the most out of moose antlers.

How far away should I place my loudspeaker?
About 20 meters, slightly behind. The call attracts, but you remain discreet.

Should I vary the frequencies?
Yes. Alternate 200 Hz for a soft whine and 300 Hz for a short grunt. This creates a sound realism that maximizes reception in the bull.

How do I maintain my palette?
Apply a thin coat of linseed oil once a season. Russian cherry will remain sound and durable.
