What is the Tango FIRE4000?

The Tango FIRE4000 is a weapon-mounted laser range finder designed for long-range shooters, precision rifle competitors, and open-country hunters. It combines laser ranging with Applied Ballistics integration to help shooters range targets and apply ballistic solutions from behind the rifle.

How far can the FIRE4000 range?

In optimal conditions, the FIRE4000 can range up to 4,000 yards on highly reflective targets, up to 2,000 yards on urban structures, and around 1,500 yards on less reflective targets such as trees.

Does the FIRE4000 use Applied Ballistics?

Yes. The FIRE4000 is powered by the Applied Ballistics ballistic engine and integrates with AB Quantum for ballistic profile management, environmental data synchronization, and field-ready ballistic solutions.

What app does the FIRE4000 use?

The FIRE4000 uses the AB Quantum app, available for iOS and Android. AB Quantum is used to pair the device, activate ballistic profiles, and synchronize environmental and ballistic data.

How many ballistic profiles can the FIRE4000 store?

The FIRE4000 stores one active ballistic profile at a time. The profile selected and activated in AB Quantum is the profile the FIRE4000 will use in the field.

What battery does the FIRE4000 use?

The FIRE4000 uses a CR123 lithium battery, which is recommended for best performance.

Is the FIRE4000 waterproof?

Yes. The FIRE4000 has an IP67 waterproof and dustproof rating, including protection against submersion in 1 meter of water for up to 30 minutes.

How much does the FIRE4000 weigh?

The FIRE4000 weighs approximately 420 grams, or about 14.8 ounces, making it compact enough for competition, training, and field use.

How do I mount the FIRE4000?

The FIRE4000 mounts to a rail. The official setup process recommends positioning the unit forward enough to avoid obstructing your elevation turret, seating the recoil lug securely, and torquing the mounting screws to 45 in-lb.

How do I zero the FIRE4000 visible laser?

To zero the visible laser, measure the distance between the center of your optic and the visible laser, mark that height on your target, rough zero at 25 yards, refine at 100 yards, and confirm alignment at 400 yards or farther when possible.

Is the FIRE4000 compatible with Kestrel devices?

The FIRE4000 is designed to work within the Applied Ballistics ecosystem, and the official tutorial references compatibility with Kestrel 5700 devices.

Is the FIRE4000 compatible with Garmin devices?

The official FIRE4000 tutorial references compatibility with Garmin 901 devices within the Applied Ballistics ecosystem.

Can the FIRE4000 be used for precision rifle competition?

Yes. The FIRE4000 is designed for long-range workflows, including precision rifle competition, training, and field applications where fast ranging and ballistic solutions are valuable.

Why use a weapon-mounted laser range finder instead of a handheld rangefinder?

A weapon-mounted laser range finder allows the shooter to remain behind the rifle while ranging targets and applying ballistic data. This can reduce movement, improve efficiency, and support faster target engagement.
