I love this topic, because I am fascinated that the CPT is clearly 1970's technology that has stood the test of time, both in function, and in the dated but very functional mechanical features. It was apparently "brought back;" I take that to mean it was out of production for some time. It apparently has a very loyal and dedicated following.
It's a very rugged and strong pilot, and can steer some pretty large vessels in blue water, even boats over 50'. It's about 50% more than a Raymarine pilot, and at this, I think it's worth it.
It's not networked, not to anything. This may deter some folks, but apparently not all.
One great advantage of this pilot is that there are knobs, right there in your face!, to adjust "rudder," i.e., gain, and deadband in real time, immediately. Sure, you can do this on other pilots, but digging through the setup menus on your MFD or AP control head is nightmarish at times, and certainly not something you'd want to do while rockin' and rollin' underway. You will probably come up with rudder and deadband settings for a couple of few points of sail and sea conditions. As a result this may well steer better than new pilots with the factory default settings or automatically generated settings, and those won't change with changes in sea and point of sail until you get into $20k+ racing systems.
If you want a strong, reliable, standalone compass steering pilot, that can be economically installed, even by yourself, this is it.
