I picked up a humminbird smartcast and I have been using it to map out bottom structure and depth on some of my local fishing spots. Overall its pretty simple to use, just cast out the sonar unit and start watching the LCD on the receiver for depth and structure info. Not sure that it would be much use as a real time fish finder, but it has enabled me to map out some sunken logs and holding trenches under heavily stained water from the shoreline, which has also enabled me to catch a few nice surprises there recently.
Anyone else tried one of these units out?
