 ## DESCRIPTION
 
-Navigation hydroacoustic buoy **WAYU GIB** of the system **[WAYU](WAYU_DataBrief_en.md)** as part of a set of four such devices forms a floating long navigation base, with the support of which positioning of the pinger is provided **[WAYU Pinger](WAYU_Pinger_Specification_en.md)**.
-The device has a monoblock one-piece construction and is made of high-strength polyurethane, automatically turns off when it gets into the water and is charged from the USB port. Doesn't require any adjustments and calibrations.
+The navigation hydroacoustic buoy **WAYU GIB** of the **[WAYU](WAYU_DataBrief_en.md)** system, as part of a set of four such devices, forms a floating long navigation base, with the support of which the positioning of the **[WAYU Pinger](WAYU_Pinger_Specification_en.md)** pinger is ensured.
+The device has a non-separable design and is made of high-strength polyurethane and polypropylene, it automatically switches on when it hits the water. It does not require any settings or calibrations. Buoyancy is provided by an easily visible float made of ethyl vinyl acetate (EVA).
