Garmin GPSMAP or Raymarine AXIOM

 


 

This week, we are comparing:

The Raymarine AXIOM 7/9/12 with the Garmin GPSMAP 742xs/942xs/1242xsv Series.

We compare the series and then side-by-side tables of the 7″ 9″ and 12′ models further below.

 

What are the main differences? Similar but different!

 

► Charting

  • Raymarine has support for more chart options like Navionics, CMAP, their own LightHouse Charts, and other 3rd party chart sources.
  • Garmin just supports their BlueChart G3 and LakeVü Series charts, which are very good but only Garmin. Garmin recently acquired Navionics, so Navionics is now part of Bluechart G3.

 

Storage | Memory

Waypoints, routes, and track storage is also different. The AXIOM has more waypoint and route storage but can’t keep as many tracks. AXIOM also has an additional 4 GB internal storage which the GPSMAP does not.

  • See the table below for details.

 

► MicroSD Slots

  • AXIOM has 1 in the back
  • 2 for GPSMAP in the front.

 

► Sonar

  • Both series have CHIRP traditional sonar but Garmin has a bit more power at 1KW vs 600W for the AXIOM.
  • Both have downscan capabilities, i.e. DownVision & DownVu. AXIOM 7/9/12 has SideVision but only the Garmin 1242xsv has SideVu.

Raymarine has RealVison 3D which takes all the data from each channel and combines it into a very cool 3D interactive screen. Garmin has Panoptix all-seeing sonar. It shows 3-D images of fish and structures, live and in real-time. But it’s not interactive.

Garmin has a cool feature for recording sonar to MicroSD. I use this feature often, to review areas that I cover during a day of fishing, in the Garmin HomePort software on my laptop.

 

► Power

Garmin GPSMAP units appear to draw a bit more power across the board than the AXIOM units do.

 

► Screen Resolution

The GPSMAP 9″ has a bit better screen resolution than the AXIOM 9″. The other sizes are the same.

 

► Rear Connections

  • Garmin has BNC video input, NMEA0183 input, and 1 additional network port on the 12″.
  • Raymarine has a USB micro B port for adding an extra card reader.

Series Summary

Raymarine AXIOM Series

Raymarine AXIOM Series

 

The Raymarine AXIOM – is the first in the series introduced in February 2017.

With a very bright optically Bonded LCD all-glass touchscreen display, the new LightHouse 3 operating system, and a new quad-core processor, it’s pretty and quite snappy.

The AXIOM has a built-in sonar, 4 Gigs of internal memory, 1 MicroSD card slot, and is available in 7″,9″, and 12″ sizes.

The AXIOM Series Chartplotters are a fully networkable boat management system with an excellent built-in fishfinder-sonar and fast quad-core processors.

They use the Lighthouse 3 operating system, and have bright screens, excellent viewing angles, built-in GPS, excellent mapping options, WiFi, and Bluetooth.

AXIOMs have a 600W 4-channel sonar that supports RealVision 3D, CHIRP DownVision, CHIRP SideVison, and a High-Frequency CHIRP Sonar.

They can easily connect to a range of other onboard systems like radar, instrumentation, autopilot, video cameras, thermal cameras, marine radio, and additional NMEA2000 networkable compatible devices and they support digital switching.

The AXIOM series also includes the AXIOM+ and the AXIOM Pro.

 


 

 

Garmin GPSMAP Series

Garmin GPSMAP Series

 

The popular Garmin GPSMAP Series was launched in November of 2016.

These are compact plotters in 7″, 9″, and 12″ versions. They offer full-network compatibility for the Garmin Marine Network and have support for sharing sonar, maps, user data, radar, IP cameras, and Panoptix all-seeing sonar among multiple units.

They are sunlight-readable touchscreen Chartplotter combo units with a powerful built-in 1kW traditional CHIRP sonar and CHIRP ClearVü scanning sonar capability which is excellent for finding structure. The 1242xsv also includes CHIRP SideVü.

They also support Garmin Panoptix all-seeing sonar. And have support for NMEA 2000 and NMEA0183 for autopilots, digital switching, weather, VHF, AIS, and other sensors.

This GPSMAP series also includes the plus and touch models.

 

So which one is Better? Opinion 🙂

Both are excellent multi-function chartplotters with solid sonar and will serve any console or pilothouse well. If possible try them out side by side to see which flows better for you.

Some swear by Garmin some Raymarine. Using one might feel better for you than the other.

If you have Raymarine and like them, and the AXIOM has all the features you need then stick with them. Realvision 3D is a nice. Same with Garmin.

Both brands are small but powerful MFD’s with big boat features at “reasonably” affordable prices.

I have used both and I’m a bit more partial to the GPSMAP but… the lack of Sidevu in the 7″/9″ units is a big negative. However, the 1KW sonar output is a big plus.

 

Note: The next GPSMAP series ie. the 743xsv,943xsv and 1243xsv do include SideVu.
