Captain Paul,

I've been researching a GSP to use in the marsh. I already have a sonar, so I'm looking at a GPS-only system to save a few $'s. I'm considering the Lowrance 5300c or the Eagle 642c. They are the same price. I'm told Eagle is owned by Lowrance and the menus look very similar, if not exact. The Eagle has more pixels, but these units are almost exactly alike. The Lowrance and Eagle seem to have better display screen than Garmin units at a more reasonable price. What is your experience with reliability and support on these units? Do you have a preference? Why? Are there any other comparable units I should consider.
Eagle and Lowrance GPS UNITS

~ Captain Paul's response to: ~ Alan T. ~

Both Lowrance and Eagle offer outstanding support on all of their models. Both units are made by Lowrance and are excellent GPS units.

The GlobalMap® 5300C iGPS GPS Chartplotter is an outstanding GPS Chartplotter. If you are considering this unit, I suggest that you also get the
MapCreate USA Series 7 Accessory Pack. Includes MMC card, MMC card reader/programmer and MapCreate USA DVD. For Windows 98 or higher operating system. This topo type of mapping will show the coastal marsh features better than other type of mapping programs.

This combo will give you unlimited mapping capabilities for anywhere in the U.S.

The Eagle 642C iGPS Chartplotter is very similar except for the type of viewing screen. In addition, I believe that the 5300 has a few more software features than does the Eagle 642C. But to be sure contact the Lowrance Support section at 1-800-324-1365 and put that question to them.

The same MapCreate USA TOPO Series 7 mapping software will fit in the Eagle 642.

Thanks, Cpatain Paul. I noticed the basemaps do not provide names for many bays and rivers in the marsh. I haven't seen any Topo maps that provide much additional identification. Does MapCreate identify more bays and bayous with names? If not, can you add the names and reload to your GPS? Are the Topo maps more recent than the basemaps? What additional information do you get from the Topo maps?

Sorry for so many questions. I'm obviously a novice and trying to investigate before I spend so much money on a GPS.



The Lowrance MapCreate USA TOPO Series 7 is Lowrance’s latest TOPO mapping software. It depicts the coastal marshland much better than the installed base map.
Check out the Lowrance web site at

IT is a full description of the mapping product.

Send me an email, describing a particular area and I will forward the USA TOPO series 7 version of that location to you.
