SI and PVC

[smashdn]

Somebody show me a pvc tree with their SI unit. Just curious if we couldn't start a sticky with pictures of neat things discovered using the Side Imaging? I think that it may help with understanding exactly what is being shown and how and it may just be really interesting to boot. I am planning on purchasing one of these units when the funds come available and I am trying to shorten my learning curve.

So if you have one of the new SI units please post up a picture of a pvc tree if it will show it and post some other neat structure (old bridges, culverts) or junk found on the bottom of the lake.
