OPTIMA II™ is so accurate that it has an added set of warning beeps that can be set for a specific altitude during normal and high speed landing approaches. This feature has been added to aid both swoopers and conservative pilots alike find the “sweet spot” for initiating landing sequences. It is recommended that your eyesight and your experience be the primary source of determining at what altitude to start your landing sequence or pattern approaches.
Hail the return of the visual warning light for audible altimeters!
