The 740s has excellent built in maps useful for navigation. These internal maps can be transferred to an SD card for use at home with your computer with Homeport software. You do not have to transfer the map every time, but you DO have to have the SD card plugged into your computer to use Homeport.
IN ADDITION to the built in maps, one may purchase cards with more detail and more features. THIS card must be plugged into the chart plotter at all times that you are using it (if you want the better charts). THIS card may be copied to another SD card to use with your computer at home with Homeport software. The copied card may not be used in your chartplotter or any other chartplotter because of encryption, but works just fine in your computer with Homeport.
IN ADDITION you may use any SD card to transfer routes, waypoints, ect. to and from your chartplotter/computer.
It is an excellent unit, and I use it often when fishing. It is a miracle when navigating our shallow waters when boating at night. It is accurate, reliable, and easy to read in daylight or at night. The screen automatically varies brightness. It has a touch screen menu and you can adjust the sensitivity of the touchscreen. It comes with a bracket mount and a flush mount kit. You must purchase the transducer separately.
Garmin has out done themselves with this one. View and clarity is great, easy to read in the sun, nice back lighting at night.You can surface mount it, or flush mount it. Includes templates for both. Accurate depth and speed readings, sounder has good images. Lowrance probably has better sounder qualities, but this is a close second.
If you want a GPS/Sounder that will last a long time with very few issues, its worth the investment.
So far, I have installed it and networked it (NMEA 0183) to my Simrad AP25 Autopilot and my Furuno 582 depthsounder.
It is working very well but I am still learning to use it.
I am impressed by its ease of use and think it will be a real asset to my fishing and cruising.
The unit itself is user friendly, and has lots of cute features, but give me the Lowrance maps for accuracy on the water.
Thankyou, Steve purser
(I love the unit its great,just that one thing bothered me)
