  We present the concept of a new Fabry-Perot instrument called BTFI-2, which
is based on the design of another Brazilian instrument for the SOAR Telescope,
the Brazilian Tunable Filter Imager (BTFI). BTFI-2 is designed to be mounted on
the visitor port of the SOAR Adaptive Module (SAM) facility, on the SOAR
telescope, at Cerro Pach\'on, Chile. This optical Fabry-Perot instrument will
have a field of view of 3 x 3 arcmin, with 0.12 arcsec per pixel and spectral
resolutions of 4500 and 12000, at H-alpha, dictated by the two ICOS Fabry-Perot
devices available. The instrument will be unique for the study of centers of
normal, interacting and active galaxies and the intergalactic medium, whenever
spatial resolution over a large area is required. BTFI-2 will combine the best
features of two previous instruments, SAM-FP and BTFI: it will use an Electron
Multiplication detector for low and fast scanning, it will be built with the
possibility of using a new Fabry-Perot etalon which provides a range of
resolutions and it will be light enough to work attached to SAM, and hence the
output data cubes will be GLAO-corrected.
