We are mounting a pair of omniscan 450 sonars on our own design boat. Is the angle at which they are mounted on the blue boat the optimal angle for these sonars? I cannot find any info on this other than main orientation angles, not angular mounting data.

Hi @andrewjamez -  
I would recommend downloading the [3D CAD](https://cad.bluerobotics.com/OMNISCAN_450_SS_BR-102105.zip) model and measuring the mounting angle used to determine the best way to mount the sonars to your vessel.

Generally, more downward gives a little better water depth measure and more upward gives longer range. Agree with Tony that what’s on the BlueBoat is a good happy medium.
