FSX Models
Main Features
Lighting and Attachment
The FSX models use an optional detachable flashlight for their illumination source.
Because the FSX scopes are rugged instruments but contain precision optical components,
never use the flashlight solely as a handle. Always keep hold of the FSX housing when in use.
