This may be the smallest full-featured altimeter yet! Smaller than a 24mm black powder
engine, this altimeter weighs in at under 0.75 oz. with battery! Optimized for “A”
to “H” powered rockets, the microAlt 4600 operates to a maximum altitude of 4600
feet MSL, with a readout resolution of +/-20 feet. This resolution, combined with
precise factory calibration and a typical accuracy of +/- 1% allows accurate data
to be acquired even from lower-flying rockets (while other altimeters may have +/-
100 feet resolution uncertainty!). Peak altitude is reported audibly in units of
feet - no conversion tables are required. Also provides two high current outputs
for firing ejection charges at apogee and 300 feet AGL, with audible continuity indication.
