The VXI-3 electrotelescope from Neuro-Saav Technologies was a specific type of electrotelescope. This compact device, weighing approximately 35 kilograms, incorporated an integrated repulsorlift generator for ease of relocation. The Rebel Alliance utilized close to twelve VXI-3 units as an early-warning network for Echo Base located on Hoth. These units encircled the base, positioned carefully at various observation points. The system's effectiveness was compromised by the high volume of asteroid and comet activity within the Hoth system, leading to its failure to identify an approaching Imperial probe droid.
