well for first m.27 is 250$ and the m.17 is 170.$ and its his big brother. then i guess you can talk about 1500 hunred depth now i can finlyfish that one reef with ling zilla is living . and it has other little goodies

that's cool.  Looks like the big difference is the better resolution.  I wouldn't pay for the feature, but you didn't have to!

The one feature that I think is cool is on the 37 (or is it 47) model is the 3D contour.  I wonder if it is one of those things that seems cool, but not really useful...
