Multiple AirMar Flush Mounted Thru Hull Installations

[genxxxx]

I have a question....How many transducers can be installed on an NavNet TZtouch2...Could these three Airmar transducers connect to the TZ or via a Furuno Hub of some kind like the BBDS1 or DFF...The transducers are B175L - B175 - B175 HW...these three transducers cover combined 40 to 250 kHz...The hull being 19 degrees there is no flat surface to mount a larger PM111LHW type transducer...I want the three transducers thru hull flush mounted at the appropriate adjusted angle....Can you please advise if this type of installation is possible.

Knowing that with TZT3 V2 software you can have two single freq CHIRP transducers paired into a Y cable the total amount of transducers could be quite a bit. The real question you want to ask is how many sounders can you have and use on a TZT/TZT2/TZT3 type network. The answer is a maximum of two fish finders can be used and one multi-beam sonar. The number of transducer will be how many you have paired to those units and then any smart NMEA depth transducers that that boat might have. NMEA depth transducers that provide just temp and depth don't count against your total maximum sounder limit. So you might have a TZT3 with the DI box running two big commercial transducers, while also running the DFF1 external sounder and the DFF3D multi-beam and still be within limits.

The trick will be finding good locations on the hull to get clear water for each of them and dealing with a little bit of interference between them if running them all at the same time. Not too many hulls have a ton of great locations for getting good clear water for a ton of transducers. That is why the combo transducers can be quite helpful.
