The Jeti Duplex EX MVario telemetric sensor module offers realtime feedback of current height and rate of climb/descent.

This tiny unit is compatible with all Duplex receivers and weighs just 6g.

An audible alert can be configured via the Jeti Box to provide a warning

when specific rates of climb/descent are achieved or when a specific altitude is exceeded, so there's no need to be staring at your Jeti Box throughout the flight.

Audible warnings can be toggled by connecting the second cable to a spare channel on your receiver and assigning to an appropriate channel.

This feature is quite useful during take-off and landing, when you might not be so keen to be alerted of changes in height or altitude thresholds.

Perfect for thermal hunting or if curious about how high your model is flying!

Also useful for models over 7kg where height restrictions must be obeyed.

The operating temperature range of the M-Vario is -10°C to +85°C

With English instructions.
