Product Codes: GAR750 and GAR750S

The standalone Garmin GPSMAP 750 chartplotter features a 7-inch display and comes preloaded with marine charts of UK and Ireland and worldwide basemap. There are two models of the GPSMAP 750, these are the 750 and 750s. The 750s includes a Sounder that requires a transducer (sold separately) which can define depth contours, show fish passing by and measure depth of objects in the water.

GPSMAP 750 features touchscreen with multitouch. The screen is easy to read in direct, bright sunlight and the processor is fast allowing for quick panning and zooming. It is also easy to change your course and review information relating to your nautical route.

Although both models have been discontinued, we still sell accessories for both the GPSMAP 750 and GPSMAP 750s. In addition you can buy the latest marine g3 BlueCharts.

The Garmin GPSMAP 750 and 750s are standalone GPS chartplotters. The 750 features a large multitouch 7-inch touchscreen display. It has been designed to be rugged and waterproof to IPX7 standards to be operated in all conditions and situations. The 750 GPS system includes marine charts for UK and Ireland and also comes preloaded with a worldwide basemap. It also features a built-in high-sensitivity GPS receiver.

The GPSMAP 750 makes it easy to plot your route on screen. It is simple to change your course and review information relating to your plotted journey. There are even flexible brightness levels making it daytime readable and it also offers low-light dimming for night time use. Full NMEA 2000 connectivity is offered for engine, fuel, wind, VHF, autopilot and other data monitoring.

Also featuring a built-in radar port the GPSMAP 750 can be used with GMR marine radar systems. The radar benefits from a plug and play installation.

The GPSMAP 750 / 750s can store 3,000 waypoints, 100 routes, 20,000 points of interest or 50 saved tracks.

The GPSMAP 750s version includes a sounder. The sounder enables the chartplotter to define the depth of the water, define where fish are and find objects underwater up to 610 metres (2000 feet) below the waters surface. However, for the sounder to function you'll need to separately buy a transducer. There are three types of transducers available. The specific one to buy depends on type of vessel/boat/rib and where or how you'd like to mount the transducer. The three are:

‣Transom Mount - for outboard powered boats and fits to the transom of the boat.
‣In-hull mount - for non-outboard powered boats for only single skin fibre glass boats.
‣Through-hull mount - for non-outboard powered boats. Ideal for wooden, steel boats, etc.

To find the perfect transducer to partner your Garmin GPSMAP 750 and your boat please complete our online transducer form. Alternatively, if you know which transducer your require (we do however recommend that you complete our online form to find the perfect transducer) you can view the comprehensive range of transducers available buy from ActiveGPS. Pictured below, transom mounted transducer, thru-hull transducer and in-hull transducer.

The 750s model also features a split screen displaying sonar and satellite navigation. The 750s also features a temperature log and graph with the included water temperature sensor.

3-D view of the surrounding area both above and below the waterline.The GPSMAP 750 and 750s come as standard with Garmin g2 BlueCharts for the waters around the whole of UK and Ireland. Additional BlueCharts e.g. Bay of Biscay and Mediterranean coast of Spain are also available on SD/microSD Card.

The very best charts are BlueChart g3 Vision SD cards. These premium charts include: MarinerEye - keep an eye on 3D information above the waterline, FishEye - provides 3D information below the waterline. Furthermore high-resolution aerial images help you to identify where you should be traveling when you are unfamiliar with the layout of the waterways. There is an Auto Guidance feature that provides a route you can follow which avoids shallow water, buoys and other obstacles.

Garmin GPSMAP 750 Questions and Answers

Question: I have a Garmin GPSMAP 750s chartplotter for my boat. I have been told by another skipper, that I can plug in another monitor into the GPSMAP 750s and have charts on one screen and sonar on another screen, when in combination mode. If this is correct what kind of monitor do I use does it have to be a Garman, and where to purchase such a monitor, can you help me?

Answer: I think you have been given wrong information. The Garmin GPSMAP 750S was a standalone unit with no capability for adding another display.
