Clear & Quick Depth Visibility 

The i40 Depth instrument display has been designed to make it as simple and speedy as possible to view the current water depth at a glance. With integrated alarms for both deep and shallow anchor, this compact display boasts excellent visibility and very low power draw. Ideal for use on RIBs, powerboats, and small yachts, the compact yet surprisingly powerful SeaTalk i40 Depth instrument display can be easily seen, even when the lighting conditions are low thanks to its oversized digits and extra-sharp LCDs.
