Default Dual 7" MFD

After pricing 9-12" MFDs, I think I have decided to go with two 7" units on a new 25' CC. Fishing out of NJ mostly for bass within 3 miles of shore (<100' depth) with occasional trips offshore.

I am thinking either raymaine e7+e7D or garmin 740+740s (or 741) either with XM Satellite weather. Not planning on a radar at this time.

I have read most of the related threads, but looking for more thoughts/opinions.

Thanks,
JSM

THe advantage the Ray system has is networking wich increases flexibility on the dual screen system. But, if that's not important either are a great option.

Look at Lowrance HDS-7 Touch and Simrad NSS7. These unit are both fully networkable, and both supports StructureScan which is something I'm quite sure you would like for your fishing.

HDS7 Touch has StructureScan built-in, NSS7 uses the external LSS-2 box for StructureScan.

$7500ish, but if I don't have to spend the money to get a very functional unit that is fine too.
PMed Semperphi this am. I may go with a garmin 740 and furuno 585 fishfinder. I like the clean look of 2 of the same units, but form follows function.

I would pony up and get the 587. It has some neat capability advancements over the 585.

The Garmin 741xs is a great update to the 740s (which is still a very servicable unit).

After looking at the problems listed on here, I'd skip right past anything that starts with "a proud subsidiary of Navico".

I had the same thought process and I am still on the fence on what to do. I have decided on the Simrad NSS7 but I am not 100% sold on the GPS user interface. So I installed one with a new TM258 'ducer (which my kids think can double as a swim platform).

I will play with it for the rest of the year. If I get used to it, I will get a second NSS7. If I can't get used to it (as a GPS) them I will get a Garmin 740.

The benfit a double MFD (multi Function device) over a Furuno 585 / 587 and a Garmin/Simrad MFD unit is redundancy. If the Garmin/Simrad unit fails offshore, get out the compass. Where as in my two MFD config, I can use either unit as a GPS or a FF. Both would need to fail.

The down side on a double MFD is that the Furuno 585/587 is probably a better pure FF. I wrestled with this for a while. But after one whole evening using the NSS7 on my boat, I am pretty happy with my direction so far... but one evening isn't much time....

BTW, specifically Gil (Semperfishing) and Abbor and Bluewaterpirate and Stilletto and the rest of THT has been a HUGE help in formulating my thought process.

thanks for all of your help and suggestions. still not entirely clear what my plan is, i have changed my mind several times already. there seem to be a lot of really great options and great new technology, and the process of researching it all has been fun.

my dad reminded me over the weekend that he and my grandfather used to do it with a compass, stop watch, and lead line.

And those who were of that generation were called fisherman



Heres a good story to read.

i'd suggest the 740s for your charplotter and the 585 or 587 for sounder. just get a good transducer no matter what sounder you go with.

Exactly what I'm installing now. Excited to have a CHIRP unit!

The 740, 585 and 587 are all not CHIRP.

Sorry....my bad
I'm installing the 740S (non-CHIRP) and
547xs (CHIRP). Total package, about $1,100 delivered.

I have run Raymarine A70D and E80's in the past and my latest boat came with a Garmin 740.

The Garmin 740 is a much better GPS than the Raymarines, but not as good sounder (I have tested back to back, with the same tranducer, down to 400m deep).

Speaking with Semper, I ended up with a Furuno 587 with 1kW SS264 pair to go with the Garmin 740 which is still hooked up to the 600 kW thru hull (lots of thru hulls....much to Sempers dismay....haha). Really good combination, highly recommended.

The 587 is a MUCH MUCH better sounder than either the Garmin and MUCH better than the Raymarine.

Only thing I miss is the nice interface between the sounder and GPS on the Raymarine, which I miss, but as I still run a sounder on the 740 as backup, I can still easily mark lumps on the 740 sounder split screen which automatically transfers into the GPS waypoints, something you cant do with the Furno 587.......

Dont compromise on sounder performance by buying two combo units (eg : 2 x 740's) just to get a back-up GPS. Buy the $30 Navionics app for your iphone, more thna adequate as a GPS backup should your main GPS fail out on the water.

As for CHIRP, unless your going for a thru hull like a B265, I would be careful as lots of reports of poor performance at cruising speeds due to turbulence. If you have a large displacement boat, a B265 or better and CHIRP look SWEET!!!!!

I'm pulling out an old Furuno and Icom to replace with the Garmin 740S, Garmin 547xs and Standard Horizon GX2150. Old dash and new dash (in construction phase now)
