Overwhelmed and confused for the complex structure underlying the Leica brand. When I was young, in the military service, I used to work with WILD, including the first laser rangefinders. With a maximum range of only one kilometer and the prize of a luxury car, they looked the last word in topography. Later the gonios and relatives were rebranded as Leica. When the Leica Geovids becames the standar of excellence in its field, I supossed their RF technology had come from WILD.
Sounds familiar Fernando. My first Wild was the T2 with the DI3 Distomat also. Early 70's. Still using the Wild/Leica Geosystems stuff. Tried a couple of Leitz instruments in the 80's but not up to the Wild equipment of that vintage.
