I got a Garmin echo map 73SV on sale a few years ago.
Has active captain, mapping, etc....
I love it, great unit I use year round, I use my Genz box off my old Vexilar as a shuttle, had to mod a bit but it works great.
While the newer models may have a sexier screen or more bells and whistles. It works great, good target separation, I really like the ice ducer for it.
Mine came loaded with lake mas which were a bit underwhelming on some bodies of water.
But I use contour mapping pretty much every trip I am out to get more accurate depths for the time of year I am fishing. I also bought a larger SD card to use for memory and to download new updates for the finder.
I plan on getting a 10" garmin for next season.
