ImmersionRC RF Power Meter V2

Detects when a quadcopter is hammer-ready and if there is a problem with the hardware, cable, connector or antenna. PowerScope mode provides a visual representation of the power radiated by the radio transmitter. Even detects transmitters that meet LBT (listen before talk) or duty cycle limits. Average or peak measurements can be taken. Built-in lithium-ion battery provides up to 8 hours of operation, rechargeable in less than 1 hour via micro USB port.
