The Uwell Caliburn G2 Coil is perfectly compatible with both the Caliburn G and the Caliburn G2. The Caliburn G2 Pod can use the new G2 1.2ohm Mesh Coil option (for MTL vaping) as well as the 0.8ohm mesh/1.0ohm MTL coils from the original Caliburn G. Whether you prefer a tight MTL hit or a wide-open DL draw, the Caliburn G series coil spectrum has got you covered.
