This is a Coleman Mach 3 series board that I have refurbished with upgraded 40 amp heater and high limit relays. It works in many other brands as well like Bullfrog, Catalina etc. I repair all Balboa, Gecko, United and Global brands of PCBs. I can sell you this one outright or repair yours for considerably less. I have been in the repair business for 45 years and repairing Spa Boards for over 20. Please feel free to contact me with your symptoms and I can give you a close estimate. Please see below for full compatibility.
