Eco teleport is an eco power in The Lost Frontier. It is the second blue eco power and fifth overall, and is the only one without any truly combative use. Received from a Precursor idol within the Aeropan research rig during the "Search for light eco" mission, its sole function is to switch places with certain Precursor statues.

To use it, press 
+ 
(for PlayStation 2) or 
(for PlayStation Portable) within range of a statue. Both Jak and the statue vanish and then after the screen clears up will have switched places. This is often used to access distant locations that are normally not within reach by other means, or to solve various puzzles, or to place the statue on a switch to unlock a door or barrier. As previously mentioned it is useless in combat, as it cannot be used to switch places with enemies (though theoretically it could be used to give approaching enemies a slip).
