The brand new coil design from Aspire called the ARC, ‘Aspire Radial Coil’, sits horizontally in the tank similar to a ‘stove-top’ design. The real trick in this design is the increased surface area of the coil for greater flavour and vapour production. Each coil is rated at 0.10-0.16ohm and uses Kanthal AF wire.
Simply unscrew the mouthpiece/top-cap, unscrew the coil mounting screw and remove the used coil. Drop another coil over the filling tube, ensuring it is sitting flush with the body of the tank around all sides. Then screw on the coil mounting screw and the mouthpiece/top-cap and that’s it!
It can even be changed with e-liquid still in the tank and as an added function, the conical coil mounting screw also acts as a spit-back protector, just in case.
