Repost of "Interpreting structure from it's "shadow"...

Note: this post was copied from http://www.crappie.com/crappie/side-...ts-shadow.html where you may find more discussion

Here are 2 snapshots...

The 1st snapshot is the .PNG directly from my 1197... (taken on my HB unit from 1 of my saved HB recordings)
The 2nd snapshot is the exact same coverage of bottom ...(taken during playback within the Humviewer program)

There are 2 things I hope to accomplish with this posting...
1. Show how to notice and identify structure by the shadow it casts..instead of the structure itself....
2. Show the value of using Humviewer for practice in learning SI interpretation...("ff" and "rew" work so much better in HV than in the HB unit)

(I left the info boxes off the HB .PNG to keep the shot from being too cluttered)
