In my trolling motor manual that was a 4 page "booklet" that referred to the US2. It indicated that the motor is equipped with a high quality built-in transducer that, along with the proper Minn Kota Adapter Cable, will provide compatibility with the sonar units listed in the following chart. For the most current list, please visit our web site

No mention of cone angle in the literature that I have :rolleyes:. It did indicate the following..
1. "Only Minn Kota brand alternator type charging systems can be used to recharge the deep cycle battery(s) connected to a Minn Kota US2 motor.
2. "You should only use Minn Kota brand alternator type charging systems. Most other brand alternator charging systems connect the deep cycle trolling motor battery(s) negative post(s) to the crank/starting battery negative post. This connection could cause a direct short in the electrical system of a Minn Kota US2 motor."
