Mamasso,
I honestly don't remember. Normally I use 40/40/40 and rarely change them.

I don't remember the settings as that was from a test we did well over a year ago. But really I did nothing special. One thing about this test vessel is that is has a very good transducer installation which is the primary factory in achieving good deep water performance.

He used a 165T-B54.
It wasn't your typical installation as it was mounted aft in one of the vessels keel mounted transducer tanks. This transducer wasn't designed to be mounted like that as it was totally submerged. He ended up making an epoxy end cap to seal the cables.

All transducers are affected by bad flow.
High frequency ones are less affected, but they are still affected.

Mamasso,
With the DFF3D you can only change the beam width viewing in the single/triple beam display mode. Your options are 20/20/20, 30/30/30, 40/40/40 or 50/50/50. Personally I use 40/40/40. If you choose to use 50/50/50 the beams will slightly over lap each other. When you choose 20/20/20, the center beam covers 10 degrees to port and 10 degrees to starboard. The Starboard beam covers from 10 to 30 starboard and the Port beam cover 10 to 30 degrees on the port side. The screen shot you posted is the Cross Section view (120 degrees) so changing the beam widths won't affect that display mode.

Mamasso,
The Beam Width is how wide the beam(s) will be.
The Beam Angle is the direction the Port/Stbd beams will be pointed.

Good morning Mamasso,
Thank you for your inquiry. I will try to explain, a normal fish finder has 1 beam width and 1 angle. The beam angle is simple, it is looking straight down on most occasions, the beam width is fixed and is determined by the transducer, elements, and frequency. So on a normal fish finder you get beam width that is fixed looking at an angle that is straight down.
With the DFF3D you get to play with 3 different beam angles. You can choose to have the beam angles look in different directions port to starboard. The DFF3D also allows you to control the beam width for example. You could set the beam width to 20 degrees, meaning the width of each one of the 3 different beams is 20 degrees port to starboard. Then you can choose what angle from the vessel port to starboard to point them in.
We do not get to decide or change the forward/aft beam width or forward/aft beam angle.
Kind Regards,
C-Bass

Hi
Some images of my DFF3D setup in the 200 meter region. I didn't participate in the fishing, but my friends were crazy about the performance. Thanks SNIPS, your information was very important for you to decide on the purchase.
They used it almost all the time in automatic mode and got readings up to 230 meters.

Mamasso,
Thank you for posting your screen shots and glad to hear you are happy with your choice.
Can you share what type of fish are in them?
