Tempest 660D LRF Dual-Lens Thermal Rifle Scope | 640 Sensor, 20mm/60mm, Laser Rangefinder

The Flagship Dual-Lens 640 Thermal Rifle Scope — Two Scopes in One

The Wave Tempest 660D LRF is the flagship of the Wave Infrared Tempest series — a revolutionary dual-lens 640×512 thermal rifle scope that functions like two scopes in one. Switch between a 20mm lens for an enormous close-range field of view and a 60mm lens for sharp 3.4x long-range magnification with integrated laser rangefinder and auto ballistics. Mil-spec aluminum, IP67-sealed, 13+ hour battery life, and backed by a 5-year transferable warranty.

Dual-Lens System — 20mm for Situational Awareness, 60mm for Long-Range Precision

The Tempest 660D's breakthrough dual-lens system transforms your night hunting experience:

20mm Lens — Close-Range Awareness. Set the objective to 20mm for an enormous field of view built for close-in work and running shots. Nothing escapes your detection. Tempest 660D owners regularly report spending 90% of their hunting time on the 20mm lens.

60mm Lens — Long-Range Precision. Switch to the 60mm lens for crisp 3.4x optical magnification paired with the integrated laser rangefinder and auto ballistics.

One scope. Two lenses. Every hunting scenario covered.

G6 Sixth-Generation 640 Thermal Sensor — Sub-18mK NETD

At the heart of the Tempest 660D is Wave's G6 12-micron 640×512 thermal sensor with sub-18mK NETD sensitivity. NETD (Noise Equivalent Temperature Difference) is the single most important number on any thermal scope spec sheet. Sub-18mK produces clean thermal images with excellent contrast — critical in humid Southern air, cold morning hunts, and low-contrast timber where heat differentials are subtle.

Ultra-Pure Germanium Objective Lenses

Both the 20mm and 60mm objectives use premium UPG (Ultra-Pure Germanium) glass for maximum thermal energy transfer and 100% sensor capacity utilization. UPG passes thermal radiation more efficiently than lower-grade germanium for a brighter, cleaner image at any magnification.

3.4x Optical with 13.6x Digital Zoom

On the 60mm lens, the Tempest 660D delivers 3.4x base optical magnification with digital zoom extending to 13.6x in Rapid and Smooth modes. On the 20mm lens, field of view extends to 1,170 ft at 1,000 yards for maximum situational coverage.

Dual-Mode Integrated Laser Rangefinder

The built-in Class 3R laser rangefinder operates in two modes. Scan Mode runs continuously and updates distance readings multiple times per second — ideal for moving targets or scanning terrain. Ballistic Mode sends a single laser pulse to the onboard ballistic calculator for an automatic real-time firing solution. Range, solve, shoot.

Automatic Ballistic Compensation

Load your rifle's ballistic data into the scope, range your target with the LRF, and the Tempest 660D calculates bullet drop automatically. The reticle shows the correct aim point for the ranged distance. No holdover math, no dialing turrets.

Military-Style Joystick Control + Large Top Focus Knob

The Tempest 660D uses an ambidextrous military-style joystick that consolidates scope functions into a single intuitive control. Combined with a large top-mounted focus knob designed for heavy-glove use, the scope delivers fast, precise adjustment in any field condition.

HD AMOLED Display with Industry-Leading Reticle Management

The 1024×768 HD AMOLED display delivers crisp, high-contrast imagery with extensive customization: 6 color palettes (White, Black, Red, Green, Golden, Violet), 9 reticle options including a no-reticle mode, 5 reticle colors, illuminated center dot with 3 color options, reticle polarity reversal, and user-selectable first or second focal plane. Picture-in-Picture, Hot Tracking, and Outline Mode round out the image control.

Rugged Mil-Spec Aluminum Housing — IP67 Sealed

Ruggedized mil-spec aluminum delivers maximum durability and efficient heat dissipation to keep the sensor running cool. IP67-rated against dust ingress and water immersion — ready for driving rain, creek crossings, and real-world hunting conditions.

13+ Hour Battery Life — Four Batteries and Charging Cradle Included

The Tempest 660D runs on two protected 18650 Lithium-Ion rechargeable batteries, delivering 13+ hours per charge. Wave includes four 18650 batteries and a high-quality charging cradle in the box — no accessories to buy separately. Field-swappable cells mean multi-night hunts without power worries.

Gun Profile Nicknaming + Easy One-Screen Zeroing

Save multiple gun profiles with custom names and stored zero distances for easy recall. The one-screen zeroing process with freeze function makes zeroing a new rifle fast and straightforward.

Free Wave IR Phone App + Onboard Media Management

The free Wave IR app (Android and iOS) pairs with the scope for live streaming, image and video management, ballistic data uploads, and firmware updates. Onboard media file management lets you view and manage captured files directly from the device.

Premium QD Scope Mount Included

Ships with a premium quick-disconnect mount featuring perfect return-to-zero and adjustable fit for rail variations.

Field Application

Close-Range Hog Hunting and Running Shots. The 20mm lens delivers a huge field of view for tracking moving hogs in dense cover and making fast shots on running game.

Long-Range Precision Shooting. Switch to the 60mm lens for open-country coyote control and confirmed shots beyond conversational distances with integrated ranging and auto ballistics.

Mixed Hunting Scenarios. Ranchers dealing with both close-quarters pest control and long-range predator threats benefit most from the dual-lens system.

Humid Southern Hog Hunting. Sub-18mK NETD is critical where humidity reduces thermal contrast — Louisiana, Mississippi, and Florida night air.

Frequently Asked Questions

How does the dual-lens system work on the Tempest 660D?

 The Tempest 660D has two physical objective lenses — a 20mm and a 60mm — that you switch between in the field. The 20mm delivers an ultra-wide field of view for close-range awareness and running shots. The 60mm delivers 3.4x optical magnification for long-range precision. Effectively two scopes in one.

Is the Wave Tempest 660D LRF worth it?

For hunters who want maximum versatility — close-range situational awareness and long-range precision in a single scope — the Tempest 660D delivers a unique dual-lens system backed by 640 thermal imaging, sub-18mK NETD, integrated laser rangefinder, auto ballistics, Wi-Fi app, and a complete accessory package. It's the flagship of the Tempest series.

Should I choose the Tempest 650 LRF or the Tempest 660D LRF?

 Both scopes share the same feature set: G6 640 sensor, UPG optics, dual-mode LRF, auto ballistics, joystick controls, HD AMOLED display, and 5-year transferable warranty. The Tempest 650 LRF has a single 50mm UPG lens with 3x magnification. The Tempest 660D LRF adds a dual-lens system (20mm + 60mm) for both wide situational awareness and 3.4x long-range precision. Choose the 660D if you hunt varied scenarios that benefit from switching between wide and long views.

What comes in the box?

 Wave includes everything needed to hunt immediately: the scope, four 18650 Lithium-Ion rechargeable batteries, a charging cradle, and a premium QD scope mount.

How does the dual-mode laser rangefinder work?

 Scan Mode runs the laser continuously and updates distances multiple times per second — perfect for moving targets or terrain scanning. Ballistic Mode sends a single laser pulse to the onboard ballistic calculator for an automatic firing solution.

Does the 5-year warranty transfer if I sell the scope?

 Yes, the Tempest 660D warranty is fully transferable, which protects resale value and gives secondhand buyers the same coverage as original purchase.
