Transducer (s) for 330 Express

[fedja]

I have allways been impressed with the knowlege and thought of the members and greatly appreciate all the advice I have been given. Thank you all in advance.

I am looking to upgrade my transducer on on 2017 330 Express. Currently I have an Airmar B60. Reads water temperarture and depth just fine but very inadequate for fishing. I am primarily fishing near shore and out to 500 ft in Dept. Targeting bottom fish but also Tuna and Yellowtail of shore. I have brand new Twin Simrad Evo 3S displays. Would you suggest keeping the B60 and adding additional tranducers or just replacing it? Would I need the Sonar 3100 module as well?

each NSS evo3s has two sonar ports. It can run the old B60 but the B60 is "traditional "CW sonar 50/200kHz 600w.
I would keep that and connect it to one of your units
It needs a 9 pin connector. You might need an adapter. I am not familiar with Simrad.

To get the benefits of the built in 1kW CHIRP and TotalScan I would use Simrads TotalScan or LSS StructureScan transducer.
Best would be a single Thru Hull mounted on the centerline. Or you could use a transom mount placed center between motors.
You NEED one of these for bottom fishing.


A B175HW would be the little extra for tuna fishing but not necessary.
