The Siren GTA features an inner chamber where you can see your coils. It has four different sized airflow holes on the bottom ring. The Siren is roughly 2-1/2" in height by 1" in width. The deck has an oil film cap that can be removed for cleaning. Use the included three-way Allen Key to loosen the deck screws.
