I know I'm beating a dead horse here but I can't say enough good things about Perfect Pass. Great company to deal with, in part due to their small size. I had an issue when installing mine, called right up to the guys who design the products and they helped me through. Went to order a second master module (for a different boat, not due to malfunction) and they remembered me a year later (or are good actors, either way, hats off to them)! Awesome company, awesome products... and they're Canadian, can't beat that!
