Have you seen some of the images coming in from the new consumer sidescan sonar models? Many images on shown on other fishing websites. The image quality is awesome. While this kind of thing has been around for a while for gov't and inst. use it appears that this looks like the next wave in consumer fishing sonar units. Hummingbird has now come out with a model.

One thing I would like to know is if you have to tow anything to obtain these images. Most commerical sidescans require you tow a long array of some kind. I hear mention of a towfish but don't know much about it.
