Tango Fire4000 Full Review - The Best Laser Rangefinder For Long Range?

Published on May 8, 2025
Duration: 37:27

This video provides a comprehensive guide to setting up and zeroing the Tango Fire4000 laser rangefinder ballistic computer. It covers downloading the necessary app, physical installation, Bluetooth pairing, ballistic profile configuration, and a detailed method for achieving a parallel zero between the rangefinder's laser and the rifle's optic. The instructor emphasizes the importance of proper mounting and calibration for accurate long-range engagements.

Quick Summary

The Tango Fire4000 laser rangefinder ballistic computer requires setup via the AB Synapse Boss app, including pairing, profile configuration, and calibration. For optimal performance, mount it on the rifle's receiver using a high diving board mount and establish a parallel zero by precisely aligning its visible laser with your optic's center.

Frequently Asked Questions

How do I set up the Tango Fire4000 laser rangefinder?

First, download the AB Synapse Boss app and install a CR123 battery. Pair the device via Bluetooth, update the app and bullet library, then configure your specific rifle and ammunition profile within the app, including units, bullet type, velocity, and zero settings.

What is the best way to mount the Tango Fire4000?

The Tango Fire4000 should be mounted securely to the rifle's receiver, ideally on a high diving board mount. This ensures the display is visible over scope turrets and provides a stable platform that is less prone to flex than rail-mounted options.

How do I achieve a parallel zero with the Tango Fire4000?

A parallel zero requires precise measurements of your optic's diameter and the distance from the optic's top to the rangefinder's laser. Use these measurements to calculate an offset, place a target at that distance, and adjust the visible laser to align with the target's center.

Can the Tango Fire4000 connect to other devices like Kestrels?

Yes, the Tango Fire4000 can connect to Kestrel devices. It can operate in AB Internal mode, using its own ballistics, or AB External mode, where the Kestrel provides ballistic solutions. The wired remote is recommended for reliability over Bluetooth.
