Garmin Air Spool and Flow Restrictor Kit for Descent Transmitters

This genuine Garmin kit includes an air spool and a flow restrictor for compatible Descent transmitter installations. Use the flow restrictor when attaching the transmitter directly to a regulator high-pressure port, or the air spool when fitting it to a high-pressure hose. Only one part is used, depending on the installation. Check the transmitter and regulator setup against Garmin’s quick-start manual before fitting.
