Raymarine DST800 Nylon Thru Hull Transducer Depth Temp Speed

In this review the Raymarine DST800 Nylon Thru Hull Transducer is assessed for small-boat owners and cruisers who need combined depth, speed and temperature sensing in a compact thru-hull package. The bottom line is that the DST800 delivers dependable, straightforward readings for Raymarine ST60, ITC-5 and i50 instrument systems, making it a sensible upgrade or replacement for boats already on that network. It is presented as a new, OEM-style nylon transducer that prioritizes compatibility and simple installation over advanced sonar imaging.

Key Features

• Combined sensors: Integrates depth, speed and temperature in one thru-hull unit so one installation provides three vital data streams to instruments.
• Nylon construction: The nylon housing resists corrosion in a marine environment and reduces the need for frequent replacement compared with some metal fittings.
• System compatibility: Designed to work natively with Raymarine ST60, ITC-5 and i50 systems so hooking it up to existing Raymarine displays is straightforward.
• New condition: Being new ensures the transducer arrives without wear or water intrusion, lowering the chance of early failure and installation troubleshooting.
• Compact thru-hull format: The thru-hull form factor gives accurate paddlewheel speed sensing and reliable depth readings at cruising speeds without cluttering the hull exterior.

Who It's For

The DST800 is best for recreational sailors, powerboat owners and small commercial skippers who already run compatible Raymarine instruments and need a single transducer that supplies depth, speed and temperature. It is particularly useful during repower or instrument upgrades when factory compatibility matters.

Boaters seeking high-resolution imaging or advanced CHIRP sonar should look elsewhere, since this unit is a basic instrumentation transducer rather than a fishfinder head. Also, owners of non-Raymarine instrument networks should confirm electrical and connector compatibility before purchasing.

Pros & Cons

Pros

• Combines depth, speed and temperature sensing into one transducer, simplifying installation and wiring.
• Nylon construction reduces corrosion risk and keeps the unit lightweight.
• Native compatibility with Raymarine ST60, ITC-5 and i50 instruments makes integration straightforward.

Cons

• Not intended as a high-resolution sonar or fishfinder transducer, so buyers wanting imaging should consider a specialized unit.

Our Verdict

The Raymarine DST800 is a practical, value-minded transducer for boaters who need dependable depth, speed and temperature data fed into Raymarine ST60, ITC-5 or i50 displays. It is not a replacement for imaging sonar, but as a new nylon thru-hull transducer it offers corrosion resistance, straightforward installation and the convenience of three sensors in one housing, making it a solid choice for instrument upgrades and routine replacements.

Frequently Asked Questions

Will this transducer work with my Raymarine ST60?
Yes, the DST800 is designed to be compatible with Raymarine ST60, ITC-5 and i50 instrument systems.

Does this unit provide fishfinder imaging?
No, the DST800 provides depth, speed and temperature only and is not an imaging or CHIRP sonar transducer.

Is the housing suitable for saltwater use?
The nylon construction resists corrosion and is suitable for typical saltwater installations when fitted correctly as a thru-hull unit.
