Default garmin 741xs vs. 840xs

I am trying to decide which one to buy...I know the basic differences, touch vs. button, size, etc., but does one perform better than the other? I am mainly using it for the chart plotter feature first and later on the chirp sonar feature and then radar. I will mainly use it in the ocean off the coast of CA on a 22' center console.

Has anyone had any issues with either model?

Touch is a huge advantage for charts. The advantage of 840xs is of course a larger screen.

7" is too small for for showing charts, sounder and radar at the same time. Do you have the option to add another 7" later when you add radar?

Besides touch and non touch.
Both have the same exact sonar circuit...sonar performance is equal.
Both use the same transducer selection.
Both have US Coastal and Inland Lakes and Rivers charts.
All other functions are the same with the exception of the 741xs having a BNC Video input.

Both have GCV 10 Side and Down Vu add on capability.

I preferred the screen size of the 840 over the touch of the 741. Otherwise they are equivalent. It is a personal choice and you will have to decide that for yourself.

THe 840 screen just appears to be much larger. (More than the 1 inch would lead you to believe)

840xs......6.4" x 4.8"...30.72 sq "
741xs......6" x 3.6 ".....21.6 sq "

40 %


A possible consideration when going to the 3 screens...

I was struggling with the same decision, because I really like Garmin's maps a lot. I made the mistake of playing with the 741xs first and that was all she wrote. I was enamored with the touch screen, but was concerned with its small size. I saw the 840xs with the larger screen, and thought I had found MFD nirvana until I tried to change menu's by touching the screen. Wow, what a let down to find it wasn't touch screen.

Honestly, I probably would have bought the 840xs if I hadn't seen and played with the 741xs, but I just had to have the touch screen after using it.

So what did I do? I went with a brand I've never owned before, a Simrad NSS8, which I found to essentially be a 840xs with touch screen. I still prefer Garmin's maps, but the Insight maps really aren't that bad, and I upgraded to Navionics Platinum Plus, which gets me 98% there. I suspect over time you'll get tired of dealing with the small screen.

This may or may not be a consideration but if you boat anywhere in the cold weather a touch screen is awfully hard to run with gloves.

For me it came down to screen height. Not only is the height of the 741xs screen shorter, another 1/2" of it is used up by the buttons that are always there. As a fishfinder and GPS screen height is more valuable than width. The 741xs screen is barely 3" of usable height versus 4.8" on the 741xs. In deeper water it makes a big difference. The touchscreen is great and I like it, but the real estate is more valuable. I don't mind the buttons at all as it is cold and wet here and I have had issues with touchscreens.

The charting capabilities on both are pretty slick. I still have yet to get any button time on the 800 series but I've made up my mind that is what I'm getting for next season. I got to work the 700 series for quite a while recently. I'm setting up one of our boats to troll for lake trout. The units that have buttons I have run are not as "easy to use" for charting, but at the same time a touch screen won't do much good in the cold.

I think the only difference in the 820xs and 840xs is the stock chart/map set. I am using mine in lakes in Canada so the US maps don't do me any good.

If you're like one of the guys on the "CHIRP v, Traditional" thread and like to look for hard bottom/soft bottom, the 741xs will give you a better zoom range to see the tells/tails/tales, the 840 is limited to only a 20' range which isn't large enough on certain depths. They both do bottom lock but with that you lose the tells/tails/tales so if you're into that the 741 would be the best choice, if you already use a tablet or touchscreen phone in your everyday life you'll love the speed of the 741 when navigating through the windows and the pinch to zoom on the charts is much faster

You could also wait until Nov 1. Garmin might announce some new screen sizes.

Can you detail this a bit more? I have not heard of this before. Does the resolution issue affect chirp or both chirp and traditional? Would it be much of a consideration in around 200ft of fresh water?

Thanks for the pic, well maybe not...... think this is the first time seeing them side by side.

I was just about set on a 741XS until I saw your pics, you may have just cost me several more 1000s of dollars in the next few months.


Do you find yourself poking the screen of the 840xs with your finger often?

Ok, I thought the way I wrote that it might have come off a bit confusing. On Sunday I had a customer that was ready to buy a 1040xs, he did all his research online got a lot of advice from his friends, on here etc. But the main thing he wanted was to see just the bottom and it's composition. So what he wanted was not the Bottom Lock feature as that only zooms the screen to just the bottom. He wanted to see the shadow or second echo the one underneath the main one that most everyone looks at. In order to do that you have to change the bottom range, the 1040 & 840 has a maximum of 20 ft, the 741 can be however small or large as you want. In some instances a 20' range isn't big enough because second echo disappears off of the bottom of the screen on the 1040. I'm not sure how many people use this but I just wanted to note that the 1040 & 840 wouldn't be good for that feature. My customer went back to the drawing board so to speak and now is getting two 741's instead of the 1040. Here's a pic I pulled off of Defender's website, the signal I'm talking about is inside the yellow circle.

On the 1040xs /840 xs no problem to get greater than 20' range for zoom
Just reset set the manual range.

For 200' manual range..you can go up to 100' etc on the bottom lock zoom.

So even if one is fishing in 75' water set the manual range to 200' etc..and the zoom is greater than 20'.

or.


The 20' for bottom zoom you see is the default...you can go into the Sonar page menue on the 1040/840s and go to bottom zoom and go to Expand and change the amount you wish to zoom.

No not talking about the range, that made the picture (the bottom detail) very small, we did that, that's what I thought the customer was talking about at 1st. We could set it up the way he wanted on the Garmin 741s, 5208 and 7215, basically all of their touchscreens. We also could set up the Simrad NSS 7 and 9 evo2's as well. We just couldn't make the window bigger than 20' on the 840 or 1040....I think it was the zoom window, I should've taken better notes.
