A new name has entered the weapon mounted rangefinder scene, the Tango Fire 4000 Ballistic Rangefinder. At first glance the spec sheet is impressive. It’s been designed with precision shooters and long range hunters in mind and gives the Vortex Impact 4000 some competition. The Tango Fire 4000 brings some extended ranging capabilities, advanced ballistic integration, and a user friendly design in a compact package.

Quick Take
The Tango Fire 4000 is worth judging by practical field use rather than product-page claims. The best gear solves a real problem in your shooting or hunting setup.
- Best use case: buy it for a specific role, not because it looks useful in theory.
- Check before buying: durability, comfort, size, warranty and whether it fits your current setup.
- Value tip: spend more only where it improves reliability, safety or repeatability.
It can range reflective targets out to 4,000 metres, trees to around 1,800 metres, and deer sized targets out to 2,200 metres, depending on the environmental conditions. These numbers would suit me, especially for engaging targets at unknown distances out to a maximum distance of 1200 meters. One of the first questions for a weapon mounted range finder is the beam divergence. The manual has it at 0.2 MRAD high and 2 MRAD wide, which is the same as the Vortex Impact 4000.
The most impressive feature for me is the integration of Applied Ballistics Elite. The same ballistic software used in high end Kestrels. This means you can create custom rifle profiles, use standard G1/G7 drag models, and get access to proven firing solutions. The unit connects via Bluetooth to the Tango Range app and can connect to third party devices such as a Kestrel weather meter. This is particularly important if you want to gain access to other environmental data as it lacks onboard sensors for temperature, barometric pressure, and humidity, so it relies on external devices or manual input for those variables.
The Fire 4000 has an OLED display with auto brightness and manual override, which helps with visibility in different light. The unit has a scan mode offers continuous ranging with angle compensation, making it handy for tracking moving game. The Tango Fire 4000 includes an inclinometer that also feeds into its ballistic solver.
It takes a single CR123A 3V battery and lasts for approx. 5,000 uses per charge. I like the housing, not just because it’s a slick black colour but its compact. I’ll have to wait until I get hands on to see how durable it is.
In terms of price, the Tango Fire 4000 is expected to retail around $1,400 USD, though Australian pricing may vary depending on importers and local distributors. At that price, it undercuts some of the more established players while still offering some great functionality. For long distance shooters looking for an unknown distance ballistic rangefinder, the Tango Fire 4000 presents a more affordable option.
Tango are new to the market, but their debut offering shows strong promise. The spec sheet shows some great features. If the field performance lives up to the spec sheet, the Tango Fire 4000 could easily become one of the best value ballistic rangefinders on the market.

Who is the Tango Fire 4000 best suited to?
It suits shooters who want an optic for rifle setup and shooting style and are willing to choose based on real features rather than brand name alone. Check the reticle, turret layout, weight and warranty before deciding.
What should I compare with the Tango Fire 4000?
Compare it against optics in the same role and price bracket. Look closely at glass clarity, turret tracking, reticle usability, low-light performance, weight and how easy it is to get support or accessories locally.
