Thanks I hadn't even seen the deep view software.
I use them both and find them excellent. You can use deepview by converting the .dat file to a .xtf. I did this with the Humminbird download Son2xtf. The deepview ver 3.0 download can be found at Download | DeepVision . I think there is a newer version out now. Here is the same structure on the 2 different viewers. The humviewer software can read the .dat file with no conversion needed.
Hope this hasn't violated any forum rules with the link. If so, moderators please delete.

Deepview seems to have a better picture!!
Excellent pics. Good info. Thanks.
The most of the difference is just in the screen shot. The actual playback is much better than it shows, but when I get serious about looking at something, I go to Deepview.
I like the measuring features in Deepview, and the Google Earth as well as the 2d feature in Humviewer.
