The coils that powers the latest Atlantis Evo tank from Aspire. They come in 2 different resistance which may seem very close together, however, the spacing and draw are very different.
 
The 0.4ohm are Kanthal Clapton coils with a 2.2mm spacing inside the coil. This gives are more airflow to the draw and therefore a slightly bigger cloud.
 
The 0.5ohm are again Kathal Clapton coils but have a 1.3mm spacing inside the coil. This gives a much tighter draw and enhances flavour.
 
Switch between EVO coils as needed to ensure you are maximizing your vaping experience.
