Our fully programmable oscillator attachment is a great option for our Dock Mounted De-Icer and Aquasweep products.We pre-program the Oscillator 360 to rotate your dock-mounted unit in 20-degree increments every 20 minutes. You set it for any radius you want, up to a full circle. Then plug it in and forget about it! The oscillator will help keep larger areas free from ice when used with the Dock Mount De-Icer, and will assist in moving more bottom debris when used with the Aquasweep. The Oscillator 360 can be added to in-place Aquasweep and De-Icer models. Made in USA, like everything else we manufacture. Comes with a two-year, unconditional warranty. Requires 110 volt power.
