This MAG Throw Off has a purposefully simple design. It is a workhorse drop throw-off, with horizontal tension adjustment and smooth, easy-to-adjust action. It gets its name from a clever magnet that"s integrated into the body of the throw off. When the handle is in the up position, it won"t release without a slight tug. The 3P 3-position butt plate allows you to choose between 3 different snare tensions, for a total of 4 immediately available snare tones. This just might be the most reliable and adjustable strainer system DW has ever built. Note that DW products are not available for further discounting online.
