I tested the system this past winter and found that I could easily cast the sensor out to its effective range from shore, dock, bank, or boat. It readily communicates with the station, provided that there is a direct line of sight between them--it won't read around a boathouse, for example. It's touted to read depths down to 100 feet, although the deepest that I have yet employed it is 30 feet. I was very impressed and think that the Smartcast may be useful not just for anglers fishing from the shore, dock, or pier but also for some boaters, including people who fish out of canoes and kayaks. If you change locations frequently, you can keep the sensor attached to a spare rod so that you can use it at any time.
