APRA Altimeter

Price: $29.95
  In Stock 0

We love PerfectFlite and what they have done for the hobby.  Due to demand and limited production, PerfectFlite does not sell through dealers at this time.

Please order directly on the PerfectFlight website.  

The APRA is an entry-level altimeter that doesn’t compromise on accuracy and capability despite its low price. It is small, easy to use, and audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps.  A post-flight warbling siren sound makes finding small rockets in tall grass easier.

Note: this is a preorder and will be shipped when the manufacturer resumes production.
