Raymarine i70s System Pack - Color, Wind, DST, iTC-5 Bundle

The Raymarine i70s System Pack is the complete color-instrument bundle for sailing yachts - the premium color-display alternative to the monochrome i50/i60 system pack, with all the matching transducers and network components needed to install a working SeaTalk-NG instrument suite from scratch. For owners building out a new instrument suite or upgrading from older monochrome displays to color, this kit gives you everything in one box - no piece-by-piece sourcing, no compatibility verification between separately-purchased components.

What's in the pack. The bundle includes seven distinct components. The i70s Color Multifunction Instrument is the central display - 4.1-inch sunlight-viewable LCD with color graphics. The Wind Transducer mounts at the masthead and reports apparent wind speed and direction. The DST (Depth / Speed / Temperature) transducer is the Airmar combined depth + speed + water-temperature thru-hull transducer that handles three data sources in one transducer assembly. The iTC-5 Instrument Transducer Converter bridges analog transducers (like the Wind and DST included in this kit) into the SeaTalk-NG digital network. The 3-meter SeaTalk-NG backbone cable is the network spine that all devices connect to. The 5-way T-Piece connector provides connection points along the backbone for additional devices. The Power Cable feeds 12V DC into the backbone to power network devices. Two Backbone Terminators cap the backbone ends - SeaTalk-NG requires terminators at both ends of the backbone to function properly.

i70s Color Multifunction Instrument - the centerpiece. The i70s is Raymarine's color instrument display - 4.1-inch sunlight-viewable LCD with optical bonding for bright colors, sharp contrast, wide viewing angle, and elimination of internal fogging. Compare to monochrome i50/i60 instruments: the color display lets you create more sophisticated graphical layouts (wind rose with directional color coding, multi-data dashboards with different colors per data type, custom backgrounds), and the larger 4.1-inch display vs the smaller monochrome displays provides better readability at the helm. For sailing yachts where instrument data is critical and helm visibility matters, the color display is meaningfully better.

Multiple data views and customization. The i70s displays virtually all SeaTalk-NG and NMEA 2000 data types: wind (apparent and true wind, both speed and direction), boat speed (from the speed transducer), depth (from the depth transducer), Tridata (combined wind + speed + depth dashboard), engine data (RPM, fuel flow, oil pressure, temperatures - requires engine data interface), environment (temperature, pressure - requires environmental sensors), fuel (capacity and flow - requires fuel sensors), and navigation (heading, course, distance to waypoint - requires GPS / chartplotter integration). Customize the display layouts with digital, analog, and graphical presentations - configure each screen to show the data you actually use.

AIS Repeater mode. The i70s includes AIS (Automatic Identification System) Repeater capability - displays nearby AIS targets visually so you can see other vessels' positions, headings, and identification data on the i70s screen. Requires an AIS receiver elsewhere on the SeaTalk-NG network (not included in this pack - sold separately). For yachts cruising in commercial-vessel-heavy waters (English Channel, US East Coast shipping lanes, similar busy areas), AIS data is critical safety information and having it displayed on the instrument at the helm matters.

Wind Transducer for masthead mounting. The included Wind Transducer mounts at the masthead via the appropriate mast bracket (typically requires a separate masthead bracket if your mast doesn't have a factory-spec wind transducer mount). Reports apparent wind speed and direction (the wind as the boat experiences it, combining true wind and boat speed effects). For True Wind data (the actual wind relative to the water, vs apparent), the i70s combines the apparent wind data from this transducer with boat speed data from the DST transducer plus heading data from the compass / autopilot - all computed automatically by the instrument when the right sensors are on the network.

DST Transducer - Depth + Speed + Temperature. The DST is an Airmar-manufactured combined transducer that reports three data types from a single thru-hull installation: water depth (the bottom depth below the boat), boat speed through water (from the integrated paddle wheel), and water temperature (from the integrated temperature sensor). One thru-hull, three data outputs. The combined approach is meaningfully simpler than installing separate depth, speed, and temperature transducers - one hull penetration, one cable run, one alignment problem to solve.

iTC-5 Instrument Transducer Converter. The iTC-5 is the bridge between analog transducers (like the Wind and DST in this kit, which output analog signals) and the digital SeaTalk-NG network. The converter accepts the analog inputs, processes the signals, and outputs the data onto the SeaTalk-NG network for display on the i70s (and any other compatible devices). Without the iTC-5, the analog transducers can't be read by the digital instruments. Including the iTC-5 in the kit is critical - it's the bridge that makes the entire system work.

SeaTalk-NG network with included backbone, T-Piece, power, terminators. The kit includes the network infrastructure needed for a SeaTalk-NG installation: 3-meter SeaTalk-NG backbone cable (the network spine), 5-way T-Piece connector (additional connection points), power cable (12V DC feed for the backbone), and two backbone terminators (cap the ends of the backbone). For a basic install with just the kit components, this network infrastructure is sufficient. For larger boats with longer cable runs or more devices on the network, additional backbone segments, T-pieces, and possibly a network hub may be needed - sold separately.

Network protocol compatibility. The i70s and the iTC-5 both support SeaTalk-NG (current Raymarine network protocol, CAN-bus-based), NMEA 2000 (the broader marine industry standard - interoperable with SeaTalk-NG via the same physical network), and legacy SeaTalk (Raymarine's older serial protocol). The triple compatibility means the kit works with whatever existing or planned electronics network the boat has - SeaTalk-NG for current Raymarine systems, NMEA 2000 for boats with non-Raymarine NMEA 2000 devices, legacy SeaTalk for boats with older Raymarine equipment that needs to integrate with the new instruments.

Display characters up to 1.7 inches tall. The i70s uses large character sizes for primary data - up to 1.7 inches tall - readable from across the helm without leaning forward to peer at the display. For helms where the instrument is mounted at the steering pedestal or on the cabin top (typical sailing yacht configurations), the large character size matters meaningfully for usability.

Sculpted rubber keypad. The keypad uses sculpted rubber buttons designed for precise operation in all conditions - wet hands, gloves, rough water motion. The tactile feedback lets you operate the instrument without looking, which matters when you need to change displays or settings while keeping eyes on the water.

IPX6 / IPX7 waterproof. The i70s is rated IPX6 (water jets) AND IPX7 (immersion to 1 meter for 30 minutes) - meaningfully more waterproof than typical instrument displays. For sailboats where the helm is exposed to spray, rain, and the occasional wave that finds its way to the instruments, the IPX7 rating is the right insurance. The IPX6 / IPX7 dual rating covers all realistic marine exposure scenarios.

Optical-bonded display. The display glass is optically bonded to the LCD - eliminates the air gap between the glass and the LCD that traditional displays have. Three real benefits: brighter colors and sharper contrast (no internal reflections from the air gap), wider viewing angle (the bonded display looks readable from off-axis positions), and elimination of internal fogging (no air gap means no condensation buildup inside the display).

Compact footprint, low power consumption. The i70s has a compact mounting footprint suitable for helm pedestals and instrument panels where space is constrained. Low power consumption (the entire SeaTalk-NG instrument network typically runs on a few amps total) doesn't meaningfully impact the boat's house battery, which matters on sailboats running on battery power for extended periods.

2-year warranty, upgradeable to 3. Raymarine backs the i70s System Pack with a 2-year limited warranty, upgradeable to 3 years free via online registration within 90 days of purchase. Register every component online after install - costs nothing and gives you the full warranty term.
