Ocean Reef Damper for GSM G.divers and M101A can be inserted on the antenna of the underwater transmitter to provide a filter which dampens distortion when the audio signal is too powerful in short distance or closed environments, such as the swimming pool.
The combination of two materials provides the filtration required to reduce the power of the transmission, making the conversation intelligible.
