De-Icer NOT included. This listing is for the horizontal float only: : Kasco De-icers come complete for suspended operation from a dock or boat in either a vertical or angle position. Angle operation by suspended method or with optional flotation unit produces an elongated pattern of agitated water. A vertical positioning produces a circular pattern. Kasco Marine offers an optional dock or piling mount. A Kasco De-icer may be operated in either a vertical or several angle positions. The de-icer may be adjusted to a maximum length of 10 feet from the mounting bracket. Kasco De-icers can be attached to our optional flotation kit to create an elongated deicing pattern in either fresh or salt water. In October 1988, Kasco Marine sent its de-icing equipment and company personnel 312 miles north of the Arctic Circle to help with the whale rescue off the coast of Barrow, Alaska. Although Kasco Marine had no official rescue invitation, they were convinced their equipment could do the job... so Kasco decided to "crash the party." At first, local officials did not take Kasco's de-icing equipment seriously, but they quickly became enthusiastic after seeing the great results Kasco delivered. There was also a friendly reception from the whales. Kasco's 3/4 H.P. Horizontal Flotation Units maintained ice-free breathing holes for the trapped whales at temperatures consistently reaching -30° F. Keeping these breathing holes free of ice, while waiting for a Russian ice-breaker, was essential to the ultimate freedom of the trapped whales.
