Default Furuno DDF-3D sounder

I got a chance to go out with a friend who put the 3D sounder on his boat today. The unit is fantastic and does an excellent job at marking fish. We are in the Chesapeake Bay so we did not go deeper than 162' of water and all the fish we found were in the typical shallower waters under birds. (We found a ton of schoolie striped bass today)

He is supposed to send me actual screen shots but here are some I took with my iPhone:

Will it show a bridge under water like these? Serious question...trying to understand the technology differences http://www.thehulltruth.com/10650921-post14.html

I dont think Furuno cares as much about structure detail as much as they do marking fish around structure. They use a much lower frequency and much higher power than others on the market. It marks fish much better than any other scanning unit I have used.

It uses 165kHz and 900w of power. vs other 400+ kHz with little power.

We did hit the Chesapeake Bay Bridge pilings and some under water rocks. Hopefully the screen shots he sends me will include them.

How shallow does it read? I'm trying to decide between this or the 711 autopilot.

Will you have that picture if you are in 150 to 300 feet of salt water? That is the difference.

Probably very few bridges at 300' in saltwater

Not sure I wasnt paying attention in less than 15' of water. We did scan the sewer pipe just north of the bay bridge in about 16' of water..

The next thing I was going to add to my boat was the 711c. However, this unit has me completely rethinking what I will do.

The unit was great. It marked fish running at 22 knots! It did a much better job at marking fish than other scanning equipment I have used.

And much deeper...and that is where the new Furuno DFF3D's lower frequency will come into play.

It will be very interesting to see the different posts of members as these units get installed and used.

Possibly when it came to having 3D or side scan......many end users have gone to other systems because they wanted either structure scan or 3D.
Or built in CHIRP.

The Simrad and Garmin 3D have been very popular... but their limitation has been no real depth capability...and not good at speed.

Furuno now has taken the 3D to another level.
Great depth and works well at speed.

This must be a very large area that is being displayed, with all that great structure you would think there must be some fish around it but I don't see any.

I have had the Simrad Structure Scan installed on my boat for two years and I must say that it marks bridges and wrecks with incredible detail, fish not so much. Schools of bait show up fairly well but not single or small groups of fish. I believe this is because it operates at 455KHZ although there may be other reasons.

I just spent a lot of money to get the Furuno 3d unit up and running and gave it a try last weekend for a short time on a family trip. I have the Simrad Structure Scan, the Furuno 3D unit and a Furuno FCV295 all running on the dash at the same time. I will use the Simrad as the plotter and only use the Structure Scan when I want to impress one of my non fishing friends with it's ability to show wreck detail. The Furuno 3D marks fish just like the FCV295 and now I have a much wider view of what is under the boat.

I would give anyone a great deal on the Simrad unit if they are interested, it's the 9 inch screen model.

Your experience head-to-head is great information to share here. Sounds like the DDF-3d is more useful for real fishing.

The thing is, I do a lot of diving and exploring, so the structure scan detail is also very useful to me. And I'm usually not diving more than 100 feet, so the limited depth isn't a huge deal.

Sounds like both are very good at their respective task.

Very promising sounder from Furuno. Thanks for sharing your first hand experience!

How shallow? I was impressed with it in 20ft for sure.

I think the Simrad is a great choice for diving and it's a lot less expensive than the Furuno. The 3D bottom detail is definitely better with the higher frequency.
