What the Zeus SR does - and the one thing it cannot do at all
Everything below is from B&G's own published specification. The right-hand column matters more than usual on this model, because the first item in it surprises people.
Included
- ✓Eight-core processorB&G's own words: our most powerful 8-core processor delivers a smoother, faster sailing experience. They credit it with the zoom and pan performance on C-MAP charts.
- ✓Touchscreen and a rotary knobB&G calls it a hybrid interface - multi-touch screen, physical buttons and a scroll wheel, plus customisable keys. Usable in gloves and in a seaway, which glass alone is not.
- ✓Two Ethernet ports, one gigabitAn X-coded M12 gigabit port and a 5-pin port. B&G says both share echosounder, radar and chart app data between units and synchronise user-created data.
- ✓SolarMAX IPS HD screen10 inch, 1280 x 800, over 1200 nits, 80 degree viewing angles. B&G states it is viewable from all angles and in all conditions, even with polarised sunglasses.
- ✓12 or 24 voltB&G specifies 10 to 31.2 V dc, so it runs directly on a 24 V boat with no converter. The Zeus S is 12 V only.
- ✓Video inputTakes an IPCAM-1, a FLIR 232 or 300 series camera, or any ONVIF IP camera.
- ✓The B&G sailing featuresSailSteer, LayLines, StartLine, RacePanel and Race Routes, with a Race Mode that switches the whole display over. B&G also builds tailored screens for cruising, racing and anchoring.
- ✓Autopilot, radar and instrumentsB&G lists NAC-1, NAC-2, NAC3 and NAC-D autopilot compatibility, HALO radar, and Triton 2 and Nemesis instruments.
- ✓Two card slotsTwo microSD and SDHC slots, so a chart card swap does not mean getting behind the panel.
Not supported
- ✗No echosounder port at allB&G's own words for this range are: No built-in Echosounder ports. This is not a sounder supplied without a transducer - there is no connector on the unit and no transducer will plug into it. Depth has to come from an S3100 or S5100 network sonar module, from another MFD on the Ethernet network that does have echosounder ports, or from instruments already feeding the NMEA 2000 bus. Note that the smaller Zeus S does have a sonar port.
- ✗The chart it ships with is not a navigational chartB&G's own cartography line reads: World wide basemap (not for navigation). Detailed chart card required. You need a C-MAP DISCOVER X or REVEAL X card before the first trip.
- ✗No NMEA 0183B&G's connector list has no serial port and the installation manual does not mention 0183 anywhere. An older DSC VHF, AIS unit or instrument head that only speaks NMEA 0183 needs a converter onto the NMEA 2000 bus first.
- ✗No weatherB&G's specification states plainly that weather is not supported on this range.
- ✗Bluetooth is fitted but unusedB&G's own specification says Bluetooth 4.0 with support for Bluetooth Classic, currently not used. The radio is in there; nothing uses it yet.
- ✗H5000 is not on the autopilot listB&G lists NAC-1, NAC-2, NAC3 and NAC-D for the Zeus SR. They do list H5000 for the Zeus S. They do not say the Zeus SR cannot drive an H5000, so ask us before assuming either way.
- ✗No published cut-out dimensionsB&G's installation manual gives external dimensions but defers the panel cut-out to a printed mounting template supplied with the unit. Do not cut a panel from a scaled drawing.
What you get
Knob, keys and glass
A hybrid interface: multi-touch screen, physical buttons, a scroll wheel and customisable keys. In a seaway and in gloves, the knob is the difference between usable and not.
Two Ethernet ports
One of them gigabit. Radar, a network sonar module, a second station and chart data all share the backbone, and user data synchronises between displays.
SailSteer and LayLines
Navigation calculated on the tacks you will actually sail, with StartLine, RacePanel and Race Routes for the race course and a dedicated anchoring screen for when you get there.
12 or 24 volt native
10 to 31.2 V dc straight off the boat's supply. No converter, no extra failure point on a 24 V system.

Fitting it
- Both displays take a bracket or a panel cut-out. The Zeus S ships with a gimbal bracket, a dash mounting kit, corner clips and a suncover; the Zeus SR ships with a gimbal mount kit, a rear mount kit, a dash gasket and a suncover.
- B&G does not publish panel cut-out dimensions in either manual - both defer to a separate printed mounting template supplied with the unit. Do not cut from a scaled drawing.
- Compass safe distance is 50 cm for the Zeus S 9 and 35 cm for the Zeus SR 10. Worth checking against a bulkhead compass before you choose the position.
- Waterproof to IPx6 and IPx7 on both, rated -15 to +55 C in use and tested to 100,000 cycles at 20 G.
- Both have an earth-ground connection point on the back and B&G expects it to be used.
- Fuse the supply: B&G specifies 3 A for the Zeus S and 5 A for the Zeus SR.
NMEA 2000 basics
- Both displays carry one NMEA 2000 Micro-C port and draw a single LEN from the backbone.
- Neither has an NMEA 0183 port. B&G's connector list has no serial port on either model, so an older DSC VHF, AIS unit or instrument head that only speaks NMEA 0183 needs a converter onto the NMEA 2000 bus first.
- AIS targets arrive over NMEA 2000 rather than a dedicated input.
- B&G's published network limits: 100 m maximum backbone, 6 m maximum drop cable, and the network supply must not exceed 3 A.
- Ethernet is separate from NMEA 2000 and carries the heavy traffic - radar, sonar and chart data between displays. Zeus S has one port; Zeus SR has two, one of them gigabit.
Every B&G chartplotter we stock
Live prices and the figures each model actually publishes. B&G states all thirteen of these for both displays, which is more than either Garmin or Raymarine manage - so nothing has been dropped from this table.

Choosing a B&G chartplotter
Three things to settle before you order. Every figure below is B&G's own published data - where they do not publish something, we have left it out rather than guess.
Neither one arrives with a usable chart
B&G is unusually straight about this, and we would rather repeat their words than soften them.
- B&G's own cartography line for the units we stock reads: World wide basemap (not for navigation). Detailed chart card required.
- A basemap is a coarse global outline. It shows you roughly where the land is. It is not a navigational chart and B&G does not claim it is.
- You will need a C-MAP card before the first trip. B&G lists DISCOVER X and REVEAL X as supported, supplied on microSD.
- REVEAL X adds satellite overlay, shaded relief, a vegetation layer and bottom hardness over DISCOVER X - B&G notes the last two are not available everywhere.
- A C-MAP chart purchase includes twelve months of updates.
The larger model is the one without a sounder
This runs the opposite way to what almost everyone assumes, and it cannot be fixed after the fact.
- Zeus S has a sonar port built in: one 9-pin Xsonic connector, single-channel CHIRP at 50 and 200 kHz, with DownScan, SideScan and Active Imaging supported. It ships without a transducer, but the sounder is in the display.
- Zeus SR has, in B&G's own words, No built-in Echosounder ports. Not a sounder without a transducer - no connector at all.
- To get depth on a Zeus SR you need an S3100 or S5100 network sonar module, or another MFD on the Ethernet network that has echosounder ports.
- If your boat already puts depth on the NMEA 2000 bus from its instruments, either display will read it and neither needs a transducer.
The sailing features are the reason to buy B&G
This is what separates B&G from a general-purpose plotter, and it is all built in rather than bought as an add-on.
- SailSteer takes the instrument data and puts it on one screen - B&G's own description is a screen that is easy to interpret and understand.
- LayLines calculate navigation on the tacks you will actually sail, rather than a straight line from waypoint to waypoint that no sailing boat follows.
- StartLine lets you ping both ends of the line and works out where you are relative to it; RaceTimer counts down and can be synchronised at the gun.
- Both displays drive a B&G autopilot over NMEA 2000, and both connect to Triton 2 and Nemesis instruments and to HALO radar.
What arrives, and what you will still need
Supplied
- Display unit
- Dash gasket
- Suncover
- Power cable
- Fuse and fuse holder
- Documentation pack
- Gimbal mount kit - metal bracket, 4 screws, 2 knobs
- Rear mount kit - 2 brackets, 4 studs, 4 thumb nut pairs and an Allen key
No chart card is included, and there is no transducer because there is no echosounder port to connect one to.
