Lowrance HDS Touch are the only units with built-in structureScan, these units also have a built-in ordinary sounder module. They HDS Touch are available in 7, 9 and 12".

My favorites are Simrad NSS which has a hybrid touch, rotary controller and button interface. Available in 6.4, 8 and 12". All except teh 12" units has built-in ordinary sounder, all units will require LSS-1 blackbox to get StructureScan.

The lowest cost alternative is HDS Gen2, these are available in 5, 6.4, 8.4 and 10.4". All of these units has built-in ordinary sounder, all all units will require LSS-1 blackbox to get StructureScan.

All HDS units and the NSS range all have built-in gps antenna/receiver.

In addition the high end Simrad units NSE8 and NSE12 are also supporting StructureScan. Units require separate gps antenna, ordinary sounder (BSM-1 or BSM-2) and StructureScan (LSS-2)

My recommendation without knowing budget and installation space is a NSS12 with BSM-1 and LSS-2.

StructureScan works well at 2' waves but the performance starts to deteriorate rapidly at 3-4'.

Thanks for the advice. More than likely it will be going on a 2013 Gamefish 27 price is a factor but don't want to skip on quality. I'm thinking the 10" or 12" screen. What about the transducer? 50/200 or 83/200 what's the difference?

To recommend a transducer I need to understand what kind of fishing and at which depths.

Forget Lowrance 83/200 and 50/200kHz transom mounts. They are low quality transducers.

The entry level for you would be Airmar B60, next quality level B164. If you need more power than what B164 can give you should probably consider CHIRP.

The picturees below are showing what the built-in Lowrance or Simrad sounder can do combined with B60. Note, depths are in Meters

The transducer is going to depend on how you fish. The pack in transducers are relatively cheap and made to give you sonar. Depending on the depth you are looking to fish you can perhaps do much better. Plus, if you decide before the boat is built, you can have the transducer installed by the boat manufacturer. They put it in the right spot and typically do a very good job of it! The transducer should work with any manufacturer MFD if you buy an Airmar with the mix and match cables. Give us more info on what you are going to do with your boat and we can get you pointed in the right direction.

Mostly slow trolling. Usually depths less than 100 ft. And yes brand new boat

B60 is what you should go for, I have two boats with B60. I also have more expensive transducers, but for trolling B60 is my favorite. The screencaps I posted above are also from slow trolling, which is my main boat fishing application.

Shopping list: NSS12, BSM-1, LSS-2 (both the electronics box and the transducer) and B60 mix n' match with blue Lowrance connector.

One alternative is to replace BSM-1 and LSS-2 with Lowrance HDS-7 Touch which has both these modules built-in. When connected to the NSS by Ethernet the HDS Touch modules will behave exactly as the standalone modules.

Why did you go from NSS12 to HDS7touch instead of HDS12?
