The ONWA KTD-TM820C is a specialized, side-mounted transducer designed for high-resolution underwater imaging. Unlike standard down-looking transducers, this unit is engineered for applications like underwater archaeology, diving, and specialized fishing where a clear view of seabed topography and underwater structures is required.

The KTD-TM820C is a multi-frequency, side-mounted transducer housed in a durable plastic (ABS + PC) casing. It is designed to provide high-sensitivity detection and accurate resolution. Its unique side-mounting capability makes it an indispensable tool for visualizing the underwater environment in a horizontal or angled plane, which is essential for identifying targets that standard vertical sonar might miss.
