which is better of the 2? I want a little more braking power when towing since i went to 35's. i pull a 6x12 tandem axle enclosed with 2-3 bikes.

 

I like the Prodigy for the reason that is is very simple and works. I have never used the Primus though.

 

I just picked up a new TT and had the Prodigy put in.
I really like it. I haven'y towed in some time, but this thing really does what it says!

 

Thats why I have one in mine and one in the wife's truck.

 

I've never been a fan of Tekonsha, had issues with a couple. I have a Haynes Genesis and I love it, seamless, no jerking, pretty much automatic. It works beautify no matter the weight of the trailer, i've used it on a single axle 15' empty and loaded, and on a 15k fifth wheel and no issues.

 

Happy as heck with my Prodigy.Works as advertised and no issues.

 

They are the same control. Tekonsha removed the self leveling device and turbo boost feature from the Prodigy and put a manual lever on the right side of the Primus to tell which way was down and to increase braking. The also gave it a little less amperage 1-3 brake axle compared to the 1-4 brake axles of the Prodigy. It was basically designed to compete against the newer a better controls hitting the market that were having to take a price cut because of the Prodigy's strong name. Technically the Primus is the P2 that is why their big brother is called the P3.

 

I couldn't have said it any better same here.

 

The Prodigy is great. Takes a few test stops to dial it in, but after that you never have to mess with it again. Seamless!

 

I had a Prodigy and went to a P-3 on my new truck.....really like it.

 

Prodigy is great P3 is better as it allows for both electric only or elec/hyd brakes

 

Prodigy all the way. I use it everyday hauling Bobcats and other heavy equipment.
