What Size Scope Do You Need for Coyote Hunting?

Release Time 2025-03-24

Coyote hunting is a challenging yet rewarding activity that requires precision, patience, and the right equipment. Among the essential gear, a thermal imaging scope is crucial for spotting and tracking coyotes in low-light or nighttime conditions. But with different scope sizes available, how do you determine the best one for your needs? We’ll walk you through the factors to consider when choosing the size of a thermal imaging scope and introduce you to an all-time hot professional thermal imaging scope.

Key Factors to Consider When Choosing a Thermal Scope Size

1. Objective Lens Size

The size of the objective lens determines how much infrared light the scope collects. Larger lenses provide better image quality and detection range but can make the scope heavier and bulkier. Common sizes for thermal scopes include 25mm, 35mm, and 50mm.

25mm Lens: Offers a wider field of view, ideal for scanning large areas quickly but with a shorter detection range.

35mm Lens: Balances detection range and field of view, making it a versatile choice.

50mm Lens: Provides the longest detection range and superior clarity but may be heavier and less maneuverable.

2. Detection and Identification Range

The larger the lens, the farther you can detect and identify coyotes. For coyote hunting, a scope with a detection range of at least 600 meters is recommended. The ability to detect movement at long distances ensures you can engage targets effectively without getting too close.

3. Resolution and Image Quality

A high-resolution infrared detector is essential for spotting coyotes in dense cover or varied terrain. Look for a scope with at least 640 × 512 IR resolution, which provides clear and detailed images, allowing for better target identification.

4. Magnification and Field of View

Magnification enhances your ability to see details but can reduce the field of view. For coyote hunting:

Lower magnification (e.g., 1.5x-3x) is preferable for scanning open fields.

Higher magnification (e.g., 5x-8x) is better for precision targeting at long distances.

Adjustable magnification scopes offer the best versatility.

5. Weight and Durability

Coyotes are fast-moving animals, and hunting them often requires mobility. A lightweight scope improves maneuverability. Additionally, your scope should be waterproof, dustproof, and shock-resistant to withstand harsh outdoor conditions.

6. Additional Features

Modern thermal scopes offer features such as laser range finding, Wi-Fi connectivity, video recording, and multiple reticle options. These features enhance usability and convenience, making the hunting experience more efficient.
