Default Garmin 1040xs or Dual Simrad NSS 7 Evo2??

Apologize in advance for the long post, but I think I'm suffering from THT-induced information overload. 2 months ago, I was 99% certain that I was going to go ahead and replace the aging Raymarine L760 (with transom-mount transducer) with a nice 10" Garmin 1040xs. I have read and re-read through nearly all the threads here and have a decent understanding of what to expect - the good, the bad and everything in between.

Recently, a neighbor had his combo unit fail on him recently, leaving him with no chartplotter or sonar/fishfinder (losing depth was not a good thing). So having redundant systems is something I have been considering lately.

Read through all things chirp-related, and while I understand a fair bit, I learn more by doing. Unfortunately for me, nobody I fish with has anything with that capability to play around with. Thanks to abbor, stiletto and semperfifishing and others for the education thus far. I've seen what both the 1040xs and Evo2 can do, and I've had the opportunity to play around with both, and could be happy with either system (touch screen isn't that important). Both were easy to learn and I was able to do just about everything I wanted to without having memorize the user manuals.

I fish in the mid/lower Chesapeake Bay and tributaries - so less than 60' in general, and usually not deeper than 35'. Might travel out past the CBBT next year but even then won't be very deep. I fish a combination of casting, trolling and jigging depending on where I am, what bait I have, what's biting, and who I'm with.

Due to the grillage system on the Regulator, thru-hulls are frowned upon. I haven't ruled one out, since I've seen it done, but for my needs I don't think it's an absolute necessity. I'd prefer to compare apples to apples between systems and transducers to make sure I get what I need (instead of what I might want).

In terms of what I think I'd need for comparable systems:

1. Simrad NSS7 Evo2 each runs about $1100 without transducers, so $2200 for the pair. I would probably get the LSS2 ($300) for one unit and the TM150M ($300) for the other unit. That way I would have redundancy for chart plotting and could run simulataneous (using both units) a structure/down scan and a chirp.
2. Garmin 1040xs with the basic transducer (77/200) runs ~$2000 (includes HD-ID/Down Vu transducer). The 50/200 transducer would add a trivial amount. What else would I need to add to make the system comparable in capability to the Simrad pair?

Granted, the 7" screen is a fair bit smaller, but if I use one unit as the dedicated chartplotter and the other unit for the fishfinder, there is little difference in screen size to using half of the 10.4" of the Garmin in split screen. At this point in time, side view is not a factor, but it might be nice to add that functionality later on.

Both alternatives will give you the same screen area. The advantage of a larger screen is more flexibility, the advantage of two screens is redundancy and easier operation (both the sounder and chart plotter window is active all the time).

The Garmin will need a GCV-10 to get sidescanning and also to support downscanning and CHIRP. In addition you will need TM150M to get the same performance as the Simrad setup.

NSS Evo2 are much more advanced units than 1040xs, NSS Evo2 are the Simrad top models which can integrate with everything Simrad has to offer. It's comparable with Garmin 82xx but with GPS antenna, CHIRP sounder and scanning sounder integrated.

If you can, wait until after the Ft. Lauderdale show to decide. Just one month away.

What about dual Garmin 840xs and a Garmin 820xs.
Using a chart chip in the 820 and built in charts in the 840 now you have two independant gps units with mapping. You can plug and play a Airmar chirp though hull transducer into one unit and if you felt like it you could put another into the other unit. Add the GCV-10 later and to either unit. Now you can have full screen GPS on one screen and all 3 sonars on the other.

I am doing exacty this and I absolutly love my set up. This off season I'm going to be adding a radar to this. Being able to see have all off this info on 2 full screens is huge for me

Thanks for an alternative suggestion.

So for a comparable system, I'd be looking at 1 840xs (~$1500) with a TM150M (~$300) and 1 820xs (~$1400) with the downvu (included). Then I'd only need the GCV-10 if I wanted to add side-vu later, correct? Would I need the chart chip or can they be networked - although the difference between the 840 and 820 is only ~$100. So roughly $500 more than the Simrad system.

If that's the case then I really need to take a look at side-by-side capabilities - it would be awesome to see them in action (not simulated) in similar conditions. I'll have to go back and look for images for both chirp and downvu for both systems at similar depths to compile as fair a comparison. Have to look at how the 2 sets of systems perform at speed (trolling vs. ~25mph cruise).

The Garmin GCV 10 downVu Side Vu has nice features for salt water use and it is utilizing CHIRP processing.

Below are a few THT members screen shots.



Still good bottom even at 39 mph.



Little bottom detail but of course this is at 50 mph....(Bass Boat)

Simrad also has a nice system.
Here are a few Simrad DownScan/Side scan shots from Team Old School.

this is a a swimmer in the water.

Why do you say this? They both seem pretty similar to me but the Garmin is considerably less money for a 10" screen or larger. Only real difference I see between the two is touchscreen.

Could be the subject matter...but based on those and what I have seen with my GCV10...I am glad I have Garmin.

Less money for less features with the Garmin. Doesn't make it a bad unit though. I have both.

Also, some might think a touch screen is trivial (especially on a boat) but now I'm always trying to touch the screen on my Garmin and buttons are just not the same.

Would I need a SonarHub for the twin Simrads to share the transducers? For instance, if I had a TM150M hooked up to one unit and that unit went out for some reason, could I display the transducer data on the other system? Or is that what SonarHub is for?

Alternate question - if I went with two Garmin 840xs (or an 840/820 mix) - is there a similar capability I would need to have to do this or would the GCV-10 do that?

thanks
David

Because NSS Evo2 is a high end unit comparable with Garmin 82xx with GRID controller, not 840xs or 1040xs which are units competing in the mid market tier.

If you study specifications and manuals (and also how the units look) you will see NSS Evo2 is comparable with Garmin 82xx, where the main difference is that NSS don't need external sounder boxes since NSS has built in 1-channel CHIRP sounder and StructureScan.

Like I said the main difference being the touch screen. If he goes with the 1040xs it has built in chirp as well. Yeah if you want the sidescan with 1040xs you have to buy an extra box but that is still cheaper than the EVO2 12" even if you do go that route. Based on the depths he said he fished it is my understanding that a 1040xs would be more than enough power.

All I will add to this is that you will not be disappointed having 2 different MFDs. I have an NSS 8 and it is always split. It would be nice to have 2 units doing their own thing.
