CTX 3030 Audio Options Wi-Stream Technology Wi-Stream wireless technology is used to communicate between the CTX 3030 and the WM 10 Wireless Audio Module. This new technology has been developed especially for the CTX 3030 to provide no perceivable delay ( less than 10 ms). This is important for detector users as lags in the audio response make it difficult to locate and pinpoint targets. Wi-Stream does not transmit audio data, like other technologies (e.g. Bluetooth).
