Default Lowrance Gen3 vs Simrad Evo2

Looking at one 12 or two 7's or two 9's. CC fishing out to 100' or so.


1) any real difference between these Gen3 and Evo2 of same size?
2) why the big price jump from a 7 to 9 ? Functions or screen size only?
3) two 7s and one 12 similar price - recommendation? Redundancy vs bigger screen? Two 9's seems best but good bit more $

Thanks

The button part of the user interfaces are a bit different, Simrad has a rotary knob, Lowrance has more buttons. I have both and have a slight preference for the Simrad implementation. The touch interfaces are identical.

HDS Gen3 has WiFi built in, NSS Evo2 requires the external WiFi-1 adapter.

HDS Gen3 supports simultaneous CHIRP and StructureScan, NSS Evo2 can today only run fixed frequencies when StructureScan is used. Some of these limitations will be removed in a coming software update but NSS Evo2 will not get to the same level as HDS Gen3 in this respect.

I have HDS-7 Gen3, NSS12 Evo2, NSS9 Evo2 and NSS7 Evo2. I prefer one 12" unit over two 7" units. A 12" will give much more screen area and will also be more flexible how the screen can be utilized. Two 9" units is far too expensive.

The competition in the 7" segment is much tougher than for the larger units. Except for screen size there is no difference between NSS7 Evo2 and NSS9 Evo2 except for a missing waypoint button, even the screen resolution is the same.

NSS12 Evo2 has a dual core processor while NSS7 and 9 has a single core. NSS12 has two Ethernet ports, NSS7 & 9 only 1.

If you ask for a recommendation for a setup with only one screen and no SonarHub or StructureScan box my recommendation is HDS12 Gen3.

I was told by the product engineer we won't see simultaneous chirp/structure on the evo2 or sonar hub..... Ever... FYI don't shoot the messenger. This was after my rep told me that a SW revision was coming to support it.

I spoke with the simrad guys at the Miami show and they said it will be on the next update.

NSS Evo2 and SonarHub will not get full simultaneous CHIRP and StructureScan like what HDS Gen3 has

Thanks Abbor, very helpful.

So your Gen3 and Evo2s have been stable enough that you don't see redundancy being a big concern? I mean I can find my way home.

You are saying no sonar hub or structure box because you have to have one of those to run both features on Evo2? I don't want t buy any extra boxes. I want sonar and structure built in.

What transducer(s) would you pair with the 12? Like I say I fish 5'-100' mostly. I have an airmar thru hull for my Garmin now. I do want something to read well on plane.

NSS Evo2 has performed well for me, I have three units 7, 9 and 12", HDS Gen3 is running the same hardware. Redundancy is always nice, but I don't see the situation for NSS Evo2 and HDS Gen3 to be different from first generation NSS which has been very reliable except for one software glitch. I have looked inside NSS Evo2 and it seems to be built according to what is normal for high reliability industrial applications (which is what I make my living out of designing) with a high quality PCB, the correct component types and gluing of heavy components to the board.

For redundancy for the charts you can always use the Navionics app on a smartphone or tablet.

You should go HDS-12 Gen3 if you want full StructureScan and CHIRP from one single MFD without any additional boxes.

B175H-W is the best transducer for your fishing, B150M will also perform well.

Thanks.

And I would need a structure scan transducer right. Think I saw you have a thru hull and transom option. Thinking transom, mounted about the keel, would provide most protection if I can find a good spot so it reads clear.

You need a StructureScan transducer, the transom mount LSS-2 work well on most boats. I have no experience with trough hull StructureScan transducers.

Firmware update for NSS Evo 2 released (look here).
Chirp and Downscan simultaneously ONLY (no chirp and structurescan).

Just to clarify, because Downscan is part of Structure Scan. The new firmware allows CHIRP and Downscan simultaneously, but not CHIRP and Sidescan simultaneously. I would wadger a guess there are minor hardward revisions in the HDS Gen3 that the SonarHub and NSS Evo2 do not have. Otherwise I would think this firmware would contain CHIRP and full Structure Scan capabilities simultaneously. So I would also guess that we will not see full CHIRP and Structure Scan on the SonarHub and NSS Evo2.

Is it beneficial to have CHIRP and Sidescan simultaneously? Can you do this with a second MFD? If it is, then the HDS Gen 3 is a better choice/product over the NSS EVO2?

I have to stop reading all this stuff, make a decision and Unsubscribe!

Thanks to all the tech guys who take time and make this a lot more understandable to English majors like me!!

To run 2D CHIRP, DownScan, SideScan and charts at the same time I think even a 12" screen is too small so not being able to run 2D CHIRP and StructureScan at the same time is not a big limitation maybe except for bassfishing and other freshwater predator fishing where the two screens are split with one at the bow and one at the helm.

At the depths where SideScan makes sense the resolution of a Simrad or Lowrance sounder in fixed frequency mode is really good when combined with a CHIRP sounder (Due to short transmit pulse lengths combined with a low Q-factor transducer with minimal ringing)

This is the Humminbird Onix 10" screen with a 4 pane view. If you want to maximize any of the panes you touch it with two fingers for about 3 seconds.

I was hoping I could do something like that with the new update but it sounds like that's not going to be the case. With my Simrads right now I have to stay on 83khz or I don't get structure scan. Sounds like at least I will be able to use a custom frequency now while using downscan on the other unit.
