Description

Premium Snow Goose Electronic Caller

Built for snow goose hunters who demand control, clarity, and flexibility from their calling system. The Overkill HD2 is a purpose-built 24V e-caller designed for larger, smarter spreads and dynamic sound placement. It is intentionally not for everyone, and that is exactly the point.

---

Who the Overkill HD2 Is For

The Overkill HD2 is designed for hunters who:

• Run bigger spreads or hybrid setups
• Care about sound placement, not just volume
• Want the ability to run horns, Ground Work 360s, or both
• Prefer flexibility and control over their audio

This is not an entry-level caller.
It is built for hunters who understand that how sound is deployed, matters.

---

Purpose-Built Audio Architecture

The Overkill HD2 uses independent left and right amplifier channels, with a dedicated amplifier per side. This architecture allows the system to drive multiple speakers while maintaining a proper electrical load per channel.

What that means in the field:

• Clean, consistent sound across wider spreads
• Stable performance at higher output levels
• Designed to support up to four speakers, including four Ground Work 360s
• No speaker stacking or electrical compromises

This design was driven by real-world use cases, not spec sheets.

True Stereo Sound + DoubleDown Tracks

All Overkill HD2 sounds are recorded by us and delivered in true stereo.

In addition, the HD2 supports our exclusive DoubleDown tracks.

DoubleDown tracks push one sound 100% to the left channel and a different sound 100% to the right channel. When paired with the HD2’s independent left and right outputs, this allows hunters to:

• Play up to four different sounds at once
• Create a more dynamic and natural sound field
• Reduce the “echo” effect that can happen when identical sounds are played across distant speakers

The result is a spread that sounds more alive and more believable, especially when birds are working.

---

Flexible, Field-Proven Control

The Overkill HD2 uses an MP3-based control philosophy by design.

• Dual MP3 players, or MP3 + phone
• Sounds can be swapped easily in the field
• Direct-wired connections for maximum reliability
• Wireless control is supported via third-party Bluetooth receivers if desired

This approach keeps the system simple, flexible, and serviceable without locking hunters into proprietary hardware.

---

24V Power System

The Overkill HD2 runs on a 24+ VDC LiFePO4 battery system using two lithium iron phosphate 12V 10Ah batteries.

Benefits of a 24V platform:

• Cleaner audio at higher output
• Improved efficiency compared to lower-voltage systems
• Designed for consistent performance in real hunting conditions

Runtime will vary based on volume, speaker configuration, and conditions, as it should.

---

Speaker Configuration Guidelines

The Overkill HD2 is designed for:

• Up to four speakers total
• One speaker per jack
• No splitters

Mixing speaker types is supported, though matching speaker types per side is recommended for best performance.

Supported configurations include:

• 4 Horn speakers
• 2 Horn + 2 Ground Work 360
• 4 Ground Work 360

---

Built With Intent

The Overkill HD2 is a custom-built unit designed and assembled with 15+ years of experience in snow goose hunting and electronic calling systems.

This caller exists because hunters kept asking for:

• Horn and 360 compatibility
• Independent control per side
• Better sound placement
• Fewer limitations
• Power to do it all

The HD2 is the answer to those requests.

Final Word

The Overkill HD2 is not about being the cheapest option.
It is about delivering a better experience for hunters who understand what matters.

Cool stuff isn’t cheap.
Cheap stuff isn’t cool.

– The little things that matter most –

---

– Anything worth doing, is worth doing right –

My dad has always been a hard-worker with passion and ability to repair anything with wheels, gears, welds, or bolts – often better than it was before. He always placed great importance on doing the job right – to stand behind your work and sign your name on the line – and has instilled that quality into me from a young age as I worked alongside him in the shop.

Those lessons from dad carry over into everything we do at Snows Down Low, and they are definitely a driving force behind the innovation and quality we build into our products. All of our electronic snow goose calls are meticulously assembled one-at-a-time in Lewiston, Nebraska. With over 35 years of electrical, mechanical, and high-performance audio experience (plus dad’s life lessons), you can be certain your e-caller is built right, and built to last.

We’re honored for the opportunity to provide you with high-quality snow goose hunting products, and to be part of your success and great memories in the field.
