I was looking at the primus vs the prodigy. The prodigy has a 360o rotation where the primus is 70. Has anyone here needed the full 360 or had issues with the primus? Would 70o be okay for going down mountain grades? Thanks

They will both work fine if mounted properly. Do yourself a favor and go with the prodigy, it's just plain easier to setup and use.

The Primus is a pendulum based proportional controller that must be leveled manually... Hence the 70 degree limit. I had one and was a good controller once I got the level set correctly. I still use a pendulum based control and they work well when set up correctly. The problem I had with setting it up manually was it was a best guess where level was. On the Voyager the control actually tells you when it's level... If you follow the instructions. The P2 or P3 self levels and uses an accelerometer to sense braking speed. Either works much much better than a time based control. As long as you set them up properly Those who had negative experiences with the pendulum based controls like the Original Primus and the Voyager must not have had the level set correctly because both of mine have been completely smooth and proportional in braking. The main reason I have not made the jump to a prodigy is because of the boost band aids. The boost button is absent from the voyager and the Primus because you can set the trailer brakes to easily lead the TV brakes by just slightly setting the pendulum more aggressively. IE when I push my brake pedal before my hydraulics kick in the Voyager has already detected deceleration and a brake signal from my foot touching the breaks and the trailers brakes are already slowing me down. No boost 1,2, or 3 needed Thanks, Jeremiah

I have Primus IQ in my truck. Bought it about 2 months ago. The new Primus IQ is the same as the old P2 as I was told by the sales guy. No leveling necessary. It has 4 boost settings. Works fantastic. It's smooth and easy to adjust.

Both units use the same sensing technology. No "pendulum" involved with the Primus IQ.

The Primus and the Primus IQ are two compleatly different brake controls. The OP asked about the Primus which has more in common with a voyager than a Prodigy. OP can you clarify, are you looking at a Primus or a Primus IQ?

It was the IQ. The guy was selling it for a real good price and I needed to save some money for the sway bars.

What is the difference between the 360 and the 70 between the two.

The Prodigy series can be mounted in any orientation from horizontal to vertical and upside down (not sure why). The Primus IQ instructions says: "WARNING The Brake Control must be mounted
from 0 degrees to 70 degrees nose up. (See Below).
In hilly terrain it is advisable to leave a margin at
either extent to keep bars from coming on when going
up and down hills."

The bars they talk about are indicators the controller is too high or too low. Mine is mounted at about 60 degrees up and never had a problem with it.
