Hi all. It is always interesting to see the various screenshots that get posted here. I've always used the traditional 2d sonar but I have been considering upgrading to add DI sonar. For those that have already added DI or SI do you feel it was worth the extra expense? If so, which do you tend to use most often (2D/DI/SI)? Just curious how much of time is spent viewing 2D versus DI or SI.
Thanks
Si yes, di not so much, all I run on the TM is 2d and GPS, but I love my si for idling and locating, I do have plans for a 360 upfront though, hope Santa is listening
Yes, yes, and yes! So I don't have SI so can't speak to that but DI is a huge game changer, I wish I hadn't waited to upgrade when DI came out. It makes "seeing" everything under water so much clearer! With 2D a brush pile looks like a blob - is it a brush pile or a school of baitfish? With DI, brush looks like brush, fish look like fish. You should upgrade to DI as soon as possible!
Like Gobbler I have my old 2D unit up front by the TM, I use that to keep me on whatever I located with the DI in the back. I also use a handheld GPS up front. I have GPS on the FF in the back so when I want to fish something I'll mark it on the FF and with the handheld, and take the handheld GPS up front. Cheap but works.
When I upgraded from 2D to DI with GPS my ability to catch fish increased 1000x, why did I wait so long? LOL
With FF prices where they are your bang-for-the-buck is fantastic!
I have both 2-D and the DI on mine. But I only use the traditional 2d because that's what I grew up knowing working on a headboat.
My current boat had 2d units at the bow & console. It's all I've ever used, well ... except for "flashers" (back in the 70's).
I put a Lowrance Elite 5DSI at the bow a couple few years ago, and I've been slightly "anti-2d" ever since :Rofl
Like "ppowell" says .... 2d gives you "blobs", while DI gives you "pictures". And while you can't always tell what's "fish" (on either 2d or DI), you can definitely tell what's a brushpile or treetop or other types of cover on your DI screen.
If you purchase a new unit, it will likely have both 2d & DI capabilities. MY unit is DI only (no 2d) but that's fine with me. It's been discontinued & the newer models have the 2d added back in. One of those types of units would give you what you're looking for, and afford you the opportunity to see the 2d image side by side with the DI image for greater/easier interpretation of what is below the transducer.
The newer units also usually come with GPS & water temp capabilities, plus card slots that can be used for screenshots (blank sd card) or using a contour map chip.
One "tip" that I would make is: a 5" screen would be the minimum size I would recommend. Especially so if you intend to use a split screen very often. :twocents
Thanks for the feedback. I've been looking at some of the Helix systems as some of the older generation units have been going on sale recently. Just curious how those with Humminbird have liked those units?
I went the Helix route not long after they came out, don't see me changing anytime soon. I bought a second unit not long after using the first one. DI opens up a whole new underwater world.Quote:

Take a look and you can compare. In the first picture, especially look between 20 foot and the bottom. Those are crappie that you see on the DI side, but are not seen on the 2D image. These shots are of exactly the same thing under the boat.
The second picture is quite similar with DI showing you had better be fishing on the bottom and suspended just under 20 feet. Yes, CHIRP has made 2D a lot better, but if you can afford DI, go for it.

Like others have said pretty much every unit except the super cheap ones come with both. So you can pick and choose. You can also run both SI and 2D next to each other on a split screen.
I find that all 3 features, 2d, DI, and SI contribute to the perfect crappie combination. The proper settings, and use, of these functions equals more fish on the hook. One caution - - - Humminbird units with both SI and DI have a compromise with the DI clarity; it does not give nearly the resolution of a dedicated DI unit and transducer. (EXAMPLE) - I have a597CI HD DI that I primarily use for DI only. - - My main unit,
899CI HD SI NAV COMBO is for all other functions. The 899 DI stinks compared to the 597 DI.
I use all 3 views as well. I'm a HB user and keep my top "quick view" button with a split screen...GPS/2D. On my middle "quick view" button I have DI only and only SI on the bottom button. Very easy to switch back and forth as needed. I used Lowrance for years and now am an avid fan of HB. However, I'm sure Lowrance has some real nice features as well. Like most fisherman, I'm used to what I have. I am very pleased with HB. I run a 959 up front with 2d and GPS only and a 999 with all 3 at the helm. As you know my equipment is now old technology and if you keep up you'll be changing every year. No thanks. Find what you like and use it and you will learn how to use it to your benefit.
THE STYLE OF FISHING WILL HELP IN DECIDING WHAT YOU NEED,I DO A LOT OF BRUSH PILE FISHING AND WITH A TRUE DI YOU KNOW IF YOU SHOULD STOP OR KEEP GOING,YOU NOT ONLY CAN SEE THE FISH IN BP BUT ALSO WITH PRATICE CAN TELL IF THEY ARE BIG ENOUGH TO FISH FOR UNLESS BP STILL HAVE LEAVES ON IT.WITH PRATICE YOU CAN TELL IF WHITE DOTS ARE FISH OR ALAGUE GROWING ON IT,SI IS MORE A SEARCHING TOOL,DI MOSTLY TO IDENIFY WHAT YOU SEE AND 2D IS GREAT FOR SPEED AND JIGGING THE BRUSH AND WATCHING YOUR BAIT AND THE FISH THAT MOVES TO BAIT AND MOVES IN THE PILE,I HAVE 2D AND DI UP FRONT AND 1199 SI AND 859 DI AT CONSOLE FOR SEARCHING AND I RUN 859 TO SEE THE FISH ON PILES SO I KNOW IF NEED TO STOP OR NOT.IF YOU ARE MOSTLY A TROLLER THAN YOU MAY WANT IT SET UP A LITTLE DIFFERENT IF YOU CAN AFFORD IT
