The Fitness Audio SM-716 UHF Wireless System features a belt pack transmitter made for fitness instructors. It is a simply made case - no hinges or flaps, no external antennas to get broken off and only one on/off switch.
16 switchable channels with more than 8 channels compatible for multiple room or dual channel systems, 9V Battery powered and the circuit board inside is protected from sweat damage by a coating of an Australian designed corrosion inhibiting lacquer.
This is the best you can get for handling the sweat! We recommend that it be used by instructors in one of our Aeromic waist worn pouchbelts or arm pouches. We also deliver it with a dab of our Fitness Audio® eGloop electrical grease in the panel plug and on the battery tags to prevent corrosion for 2 years or more. 
Replacement transmitters in NZ are generally supplied in the 650-670Mhz range.
