Why doesn't the Tango Innovations FIRE 4000 WMLRF have built-in environmental sensors?

When designing advanced Weapon-Mounted Laser Rangefinders (WMLRF)—essential gear for any marksman—manufacturers must make critical design trade-offs. One such choice is the intentional omission of built-in environmental sensors like thermometers, hygrometers, or barometers. While this may seem surprising, it is a practical decision driven by the need for precision. Sensors mounted directly to a firearm can be affected by barrel heat and vibration, leading to inaccurate data. By relying on external or linked data, the FIRE 4000 ensures the ballistic solutions remain reliable when it matters most.
