I have one of their models to protect my granite steps going into the water. For what they charge you to install steps I wanted to avoid any ice damage if possible. This device works great. At it's shallowest, the water is only 12" deep to about 3 feet. I lay out the air hose in a circular pattern in front of the steps. It protects several feet in any direction. In the heart of the winter when the ice gets really thick however, it only protects directly above the circle of bubbles that are created. I would suggest getting the model with an air hose larger than what you want, that way you can zig zag it along your shorline and get maximum protection.
It is very cheap to operate and I have it on a thermostat so it only comes on when the temp is below 35 degrees and goes off when the temp is above 45 degrees. This saves a little bit of money in December and March.
