Sword setup. 295 vz tzt19

[prioritiesnz]

Hey Guys. I'm new here. My name is Jared and I'm based way down in New Zealand.
I have built a trailerable 9m (30ft) sport fisher out of a blackwatch 26. The current electronics package are a tzt19 with a 275LHW and a 295 with a 38BL-15HR and 200b-8b.

The 295 transducers were mounted in hull in wetboxes shooting through the fiberglass hull. They were not performing well at all. So I pulled the lot out and sent to our Furuno Agent here in NZ for testing. All tested OK.

So my predicament is. Do I go ahead and reinstall the 295 and pocket mount the transducers thruhull OR would I get a lot better performance putting the 275lhw to the 295 and purchasing a dff3uhd and a R509 to run through the tzt. Obviously a lot of cost difference going the r509 route. Will it be worth it?

Our sword fishing is normally around 500-600 meters (roughly 1500-2000ft)

Oh. Should mention. I had the local Furuno guru come and make sure the 295 was all wired correctly (taps etc) and settings were correct in water before re testing and pulling the gear out.

prioritiesnz,

When is comes to using any transducers that to shoot through the hull, I am not a fan, You simply can not get the best performance out a transducer that is a shoot-through-the hull types. The best fish finder performance that you can get is using wet faced thru-hole transducers.

You can either re-use the FCV295 or add a DFF3-UHD to your TZT Suite. What you really need to do is select the right transducers that will get the job done in sword fish detection. So here is the data on the following transducers that you mentioned:

R509LH: 3 kW of power on Low Frequency 28-60 kHz. Range of 10,000 ft (3,040 meters) 2 kW of power on High Frequency 130-210 kHz Range of 1500 ft (457 meters)

R509LH-W: 3 kW of power on Low Frequency 28-60 kHz Range of 10,000 ft (3,048 meters) 1 kW of power on High Frequency 150 to 250 kHz (25° constant beam width) Range of 500 ft (152 meters)

B275LH-W: 1 kW of power on Low Frequency 42-65 kHz Range of 3000 ft (914 meters) 1 kW of power on High Frequency 150-250 kHz (25° constant beam width) Range of 500 ft (152 meters)

This is so important in the choosing and properly installing the best transducers to use for your fishery.

I hope that you find this information is helpful..?

Thanks for this. Yep.
I guess to narrow my question down I'm wondering if the R509 will perform much better than the 38BL-15HR I already have for sword fishing? Regardless of install as either option will definitely be going back in wet face mounted.

prioritiesnz,

If you wanted to reuse both the CA38BL-15HR and the CA200B-8B transducers as wet-faced transducers that they were designed, and not as shoot-through-the hull configuration. They are very good commercial grade transducers and can be utilized for fishing for swords.

Here is the specifications for those transducers:

CA38BL-15HR 3kW of power with frequency of 38kHz. Transducer's beam width is 12.5° X 21° degrees.

CA200B-8B 2kW of power with a frequency of 200kHz. Transducer's beam width is 5.5° degrees

Drill holes in the boat and mount these wet faced and you will never look at the TZT again the 200 B-2B is mint tranny
