As an added convenience, this finder is compact in size, with an easy-on, easy-off mounting system that allows it to go almost anywhere. The 937c DF2 Combo is built tough with fully gasketed and waterproof construction so it even floats, and is assembled in the USA with a manufacturer's one-year warranty.
