Thought I'd open a discussion on brake controllers. I started with Tekonsa Voyager. Moved to the Prodigy. Finally the Prodigy P3. Didn't like the full on ability of the Voyager. The Prodigy was a perfect fit. Once the Prodigy P3 came out with error codes in English I figured why not? The P3 does many things I'll never need. The Prodigy was more than enough and slightly more adjustable. Error codes will need a cheat sheet versus the plain English of the P3.
The Prodigy and Prodigy P3 use proportional braking. Bought both Prodigy's on Ebay at considerable savings. What are you using?
