Fishing at night? Add a light function to your Deeper. Simply swap the original cover for a transparent one and select the night fishing mode on the Fish Deeper mobile app. The Deeper Night Fishing Cover is specially designed to allow you to use your Deeper Smart Sonar at night. The translucent orange cover of the Night Fishing Cover makes a bright flashing LED light visible, ensuring that the device is easily visible in the dark and from a distance. It is also ideal for misty or rainy conditions when visibility is poor. This small, lightweight replacement cover is easy to install.
