Suggestion from experienced cachers for a GPS unit?? in GPS Posted September 9, 2002 Ok, since we are offering suggestions, I'll say that what I have is a SporTrak Pro, and it has worked really well for me, and I like the compact size vs the Meridian. Only tradeoff is the Meridian has expandable memory, and a slightly larger screen. Both have the same antenna and receiver circuitry. If you travel all over the US and needs LOTS of maps onboard, go for the Meridian and a 128mb SD card. A SporTrrak Pro holds the Streets & Topo for my entire state, though, with about 6mb left over, so for me it is wasn't worth the extra weight & bulk. Also, even with the smaller patch antennas the eTrex line works ok in the pine woods we have in the south. (Don't get me wrong -- it's not as good as a Quad Helix, but good enough.) There's probably a greater difference in denser cover, like the Pacific Northwest, though.
