Tortoise™ is a lightweight, (under 20 lbs) DC powered transmitter system composed of dual independent, transmitter modules giving the user freedom to transmit on any 2 frequency bands from anywhere without expensive and bulky additonal transmitters. Each Tortoise™ is housed in a high impact ABS water resistant case. Each transmitter module has a built-in agile frequency synthesizer, dynamically controlled power amplifier and remote control of all transmitter parameters via an IR remote controller. Remote adjustments include power level, channel or frequency assignment and transmit On/Off.
