Few measurements are more important to safe boat navigation than knowing the water depth...especially when the bottom is hard and the water is thin. The ST40 Depth instrument will provide a clear indication of depths to 400', and can also be set to alarm you for shallow and deep water. The flush-mount transducer will barely cause a ripple due to its nearly flush shape (for hulls up to 1.87" thick.) Also indicates minimum depth since power-up.
