VERTICAL SPEED INDICATOR
Patent Product, Integrates the highly Reliable MEMS Sensor
Precise, Durable, Accurate (reading), Free from Frequent Regular Calibration
1. Evenly allocated scale: accurate indication, easy to read;
2. Large range available: unlike the metal diaphragm structure, this gauge enables steep haul-up and haul-down without exceeding the available range.
