Tango Fire4000

Weapon-Mounted Precision: The Tango Fire4000 Revolution

The Tango Fire4000 is more than a rangefinder, it's a complete ballistic system that mounts directly on your rifle. This means you no longer need to come off your gun during long-range shooting to measure distance. You stay in position, keep your target in view, and get the exact distance information you need, precisely when it matters most.

Three Versions for Different Disciplines

Tango Innovations developed the Fire4000 in three variants, each tailored to specific applications within shooting sports:

Fire4000 UltraLite is the lightweight version for hunters who value mobility. At just 14.8 ounces, this version adds minimal weight to your setup, ideal for those who cover long distances on foot during hunting sessions but still demand professional measurement precision.

Fire4000 Sportsman targets recreational shooters and those who train regularly at the range. This version offers all core functionality you need for effective training and developing your long-range skills without unnecessary complexity.

Fire4000 Elite is built for competitive shooters, professionals, and anyone who wants to extract maximum performance from their equipment. This version contains all advanced features and is constructed for intensive use under demanding conditions.

Technical Specifications that Make the Difference

The Fire4000's dual laser system is cleverly designed. The invisible laser (Class 1, 905nm) measures distances up to 4000 yards, which translates to nearly 3700 meters. This range naturally depends on target type: on reflective targets under ideal conditions you achieve the full 4000 yards, on urban structures approximately 2000 yards, and on vegetation or non-reflective surfaces around 1500 yards. The visible red laser (Class 2, 635nm) is used for zeroing your rifle and is effective up to 100 yards.

The OLED screen displays distance and angle immediately, with adjustable brightness so you maintain clear visibility of your data in different lighting conditions. Particularly practical is the ability to display the screen both vertically and horizontally, and the device can be mounted on either the left or right side of your rail. With a long press of two seconds, you easily switch between different screen orientations.

The response time of 0.5 seconds ranks among the fastest in its class. You feel a vibration as soon as the device locks onto your target, giving you confidence that you have an accurate measurement. This speed is essential in dynamic situations or when you need to quickly range multiple targets.

Applied Ballistics Integration: The Power of Professional Ballistics

The strategic partnership between Tango Innovations and Applied Ballistics delivers seamless integration with the AB ecosystem. Through the AB Synapse - BOSS app or the newer AB Quantum app (available for both iOS and Android), you gain access to the gold standard in ballistic calculations.

You can directly synchronize your AB profiles with the Fire4000, with real-time updates of environmental conditions being processed. The Fire4000 is also compatible with other AB tools like Kestrel weather meters and Garmin devices via ABE (Applied Ballistics External) mode. This flexibility means you can integrate the Fire4000 into your existing workflow, or use the device as a standalone unit.

Practical Applications in Precision Shooting

For precision rifle competitions, the Fire4000 offers a significant advantage: you don't need to come off your rifle between stages or during unknown distance shooting. You remain in your shooting position, aim at your target, measure the distance, and take the shot immediately. This workflow saves precious seconds and increases your consistency.

When developing DOPE (Data On Previous Engagement) for your specific ammunition and rifle, the Fire4000 provides the accurate distance measurements you need to verify your ballistics. Angle compensation is essential here, especially on ranges with varying terrain where you're shooting uphill or downhill.

For shooters who work with handloaded ammunition and take their load development seriously, the combination of accurate distance measurement and professional ballistic software through Applied Ballistics is indispensable. You can test different loads at known distances and immediately see how they perform under real-world conditions.

Mounting and Power Supply

The Fire4000 mounts via an integrated Picatinny rail mount, meaning installation on virtually any modern precision rifle is straightforward. You determine the rail position yourself, depending on your other optics and preferences.

Power comes from one CR123A 3V battery. When installing, note that the positive side faces inward and the negative side outward. This commonly used battery is readily available and provides sufficient capacity for extended shooting sessions.

Reliability and Warranty

Tango Innovations offers a comprehensive three-year warranty on the Fire4000 series. This coverage includes defects in electronic components and other internal issues inherent to the device. Should a problem occur within this period, a replacement unit will be sent to you. The warranty does not cover damage from external forces or intentional misuse.

For shooters who want to extract maximum performance from their equipment and accept no compromises in precision, the Tango Fire4000 represents a new generation in weapon-mounted ranging. The combination of speed, range, and professional ballistics integration makes it a valuable tool for anyone serious about long-range shooting.
