Raymarine A22154 DST800 Depth Speed Temperature Transducer Thru-Hull

The Raymarine DST800 is a Smart™ TRIDUCER® multisensor that combines depth, speed, and temperature functions in one compact, low-profile plastic thru-hull fitting. This innovative transducer eliminates the need for multiple sensors or a dedicated depth sounder by integrating digital signal processing directly inside the housing to deliver accurate data to your chart plotter, radar screen, or digital display.

Key Features:

• Three functions in one compact housing: depth, speed, and temperature sensing
• Low-profile plastic thru-hull design for clean installation
• Wide port-starboard fan-shaped beam pattern finds bottom on high-deadrise hulls and heeled sailboats
• Smart™ technology with integrated digital signal processing
• Compatible with ST40, ST60, ST70, i40, i50, and i70 instruments
• Includes 13.7 meter (45 foot) cable with 1/8" spade connectors

The DST800's wide beam angle makes it particularly effective for sailboat applications where heel angle can cause traditional transducers to lose bottom reading. The integrated digital processing ensures clean, accurate data transmission to your marine electronics without interference or signal degradation.
