Integrated Rangefinder is a technology that can be researched at the Troop Center in Tech Level 4. It costs 300 food, and gives all Troop Center units +1 Line of Sight. In addition, all Troop Center units, except the Mounted Trooper and its upgrades, get +1 range. This technology requires Portable Scanners to be researched first. Integrated Rangefinder is available to all civilizations except the Gungans and Royal Naboo, though the Gungans have FarSeeIn Binoculars instead.
This technology has the same effect as MacroBinoculars, but at 4 times the price. It's useful for civilizations that rely heavily on Troopers, but it can wait until other, cheaper technologies have been researched.
"Like the Portable Scanners technology, this Tech Level 4 upgrade enhances most Troop Centre units with additional view range and weapons range."
