Key Features of the Rattler V3

Thermal Sensor Performance

640×512 VOx Sensor

The Rattler V3 uses a 12μm uncooled VOx sensor with 640×512 resolution, offering rich thermal contrast and the ability to distinguish targets through brush, fog, and pitch-black darkness.

Sub-15mK Sensitivity & Shutterless Operation

  • NETD ≤15mK: Captures subtle temperature variations
  • Shutterless core: Delivers real-time imaging with no screen blackout or mechanical shutter sounds

Lens and Detection Capabilities

50mm F1.0 Lens

The large-aperture F1.0 lens gathers more infrared energy, boosting low-contrast target visibility at long distances.

Detection Range Up to 3540m

  • Vehicle-sized targets: Up to 3540 meters
  • Human-sized targets: Up to 1800–2000 meters

High-Res Display and Imaging Tech

2560×2560 OLED Display

The circular AMOLED display offers:

  • Exceptional pixel density
  • Ultra-clear reticle rendering
  • Seamless eye alignment with natural sight picture

Image Boost 2.0 & Zoom Pro

  • Image Boost: Sharpens edges, improves clarity
  • Zoom Pro: Maintains image structure during digital zooming

Magnification and Zoom Options

3.5× Base to 28× Max

Zoom smoothly from 3.5× to 28× using step or continuous zoom modes.

PIP Mode and Freeze Zeroing

  • PIP (Picture-in-Picture): Displays 2× zoom inset without losing full-frame vision
  • Freeze Zeroing: Capture image and align reticle without holding steady under recoil

Laser Rangefinder Integration

905nm Eye-Safe Class 1 LRF

The LRF is seamlessly integrated and offers:

  • Ranging distance: Up to 1200m
  • Accuracy: ±1 meter
  • Modes: Single and continuous scan

±1m Accuracy with Built-in Calculator

Pairs with ballistic engine for instant holdover recommendations—critical for ethical long-range shooting.


Reticle and Zeroing Profiles

10 Reticle Options

Choose from 10 reticle patterns with color options (red, green, black, white) for any light condition.

5 Zeroing Profiles and Freeze Mode

Store zeroing setups for five rifles or ammo loads, each with unique magnification, reticle, and correction values.


Ballistic Calculator and Onboard Tools

Automatic Holdover with Range Data

When LRF is used, the ballistic calculator auto-displays holdover markings, helping shooters compensate without guesswork.

Hot Track, Distance, and Pitch Tools

  • Hot Track: Locks onto warmest object
  • Stadiametric ranging: Manual target height-based distance estimate
  • Incline angle and compass readout: Display pitch, heading, and elevation info

Recording and Media Features

64GB Built-in Storage

Ample space for:

  • Recoil-activated videos (RAV)
  • Photo snapshots
  • Microphone-enabled audio

All footage is timestamped and stored in standard formats for easy sharing and editing.


Wi-Fi Streaming and Mobile Sync

Hotspot & AGM App Support

  • Use the AGM Connect app to:
    • View and record live feed
    • Transfer media wirelessly
    • Adjust scope settings remotely

Power System and Battery Runtime

NE-4400 Battery Pack

  • Rechargeable Li-ion pack
  • USB-C quick-charge supported

≥5.5 Hours Operation + USB-C Support

For extended missions, connect a power bank via USB-C to continue using without swapping batteries.


Build Quality and Durability

  • IP67 rating: Waterproof and dustproof
  • Shock resistance: Up to 1000g / 0.4ms
  • Temperature range: Operates in -30°C to +55°C

This is a true field-grade optic—ready for rain, dust, and recoil from high-powered calibers.
