Love that you can change out the blades to work for wood or metal cutting purposes and that it uses a separate reservoir for the cooling water so you aren't just using dirty water over again.
Great thing about the saw is it has a fresh water reservoir serving as coolant to the blade. The competition uses a water reservoir where the water is recycled. It fouls quickly when you are cutting multiple frags.
#2 The drain option is a great idea that will help with cleaning and draining the saw after operation. The blade choice is very useful that allows the DB-100 to be used in the garage for other none reef applications.
