TZT2 Transducer Query

Hi Guys,
Currently running a TZT2 with an in hull Airmar 2kw PM111LM transducer, DFF3 and Hub101 primarily for deep drop fishing 400 to 1000metres. Having some fun trying to get the best out of that setup but that is for further discussion later! Looking to add a low profile tilted element directly to the TZ that will give me Accufish, Rezboost and Bottom Discrimination for shallower water and would like to know if the 526TID-LTD 1Kw unit will support these features. I know that the 526 TID-HDD will work but that thing is the size of a small house!! It appears that my only other low profile options are 600w units. Comments would be appreciated.
 
Good afternoon Widgetman,

Thank you for your inquiry. Right now the only tilted element low profile transducers that will give you bottom discrimination, Accu-Fish, and RezBoost are:

525T-LTD/12
525T-LTD/20
SS60-SLTD/12
SS60-SLTD/20

The 1kw low profile tilted element transducers are not on the approved list for those functions.

Kind Regards,

C-Bass
 
Hi C-Bass,

Many thanks for the prompt reply. My homework suggested that was the case but had a small hope that the 526TID LTD may have worked.
Will any of those functions (Accufish, Resboost or Bottom Descrimination) work with the TZ?

Cheers
 
Good evening widgetman,

The not sure what you mean by the "TZ?" Does that mean TZT14? or Nobeltec Time Zero?

The TZT14 does not have a built in sounder module so you would need to purchase a DFF1-UHD for accufish and bottom discrimination. Currently the only MFD products that has the RezBoost feature is built into the TZTL12F and TZTL15F.

The DFF1-UHD is not compatible with low profile tilted element transducers for Bottom Discrimination and Accu-Fish.
 
Hi C-Bass,
Sorry for any confusion but I have the TZT2 12". So none of the 3 functions listed will work with the 526TID LTD
even with the addition of a DFF1 or a matching box?
Cheers
 
Good afternoon widgetman,

Sorry for the late reply. Because it is a TID transducer it will tell the internal sounder in the TZT2 unit that it is not compatible for Rez Boost, Bottom Discrimination or Accufish. You could open up the transducer cable and snip the TID wire but it would void the warranty on the transducer and the internal fish finder of the TZT2 has not been calibrated to work with those transducers. So although it would unlock the features, the data it presents may not be accurate because that type of transducer has not been calibrated and the algorithms have not been adjusted. The DFF1 does not does not do bottom discrimination or RezBoost. The matching box is used for impedance mismatch not for the other features in question.

Hope that helps explain it a little better.

Happy New Year

Hi C-Bass,
Thanks for the detailed reply and all the best for the New Year for you as well.
Have another query for you regarding setting up the TZT2 with the Airmar PM111LM Transducer. I am not sure about setting the correct parameters into the TZT2 and have attached a screen shot of the current settings for your comments. Instructions are very vague in the setup manual.
 
Hello again C-Bass,
Thought I should also add the Airmar info for you. The low frequency side is 38-75 and the medium (high) is 80-130.

Cheers

I have an issue attaching the screen shot photo so will have another attempt.
 
Good morning Widgetman,

THank you for your inquiry. I have a couple questions of the photo you provided in your last post. The bandwidth of the low frequency of the PM111LM is 38-75 kHz. In the photo above you have the Low Frequency Max to 118 kHz. The min- max should be set to the specifications of the transducer connected. Typically for the low frequency values and the high frequency values i recommend setting those numbers to the mid-point of the available bandwidth per the transducer specifications. For example for the low frequency I would set that value for 56 or 57, then give yourself enough bandwidth to reach the high and low point of the transducer. So when you use the frequency adjust you can reach 38 kHz and 75 kHz. The frequency adjust is the setting that the transducer is actually transmitting at. For example, if you chose 56 kHz for the low frequency number and you have the Frequency Adjust set to 0, then the sounder is transmitting at 56 kHz. If you move the frequency adjust by +10, then the sounder is transmitting at 66 kHz. I for deep dropping lower is going to be better, try around 42kHz on the low frequency. To get to 42kHz, again set the centering frequency on the transducer setup around 56 or 57 kHz. If you chose 56 kHz then set the frequency adjust for low frequency to -14. I would also try setting the Medium frequency to something around 75.

Couple other things to check:
Make sure you have the tap settings right on the DFF3, what are yours currently set to?
Transmission Rate: Set this value to the highest number, manual transmit rate is better.
Transmission Power: Set this value to the highest number, no auto power.


Have fun out there.

C-Bass.
 
Hi C-Bass,

Many thanks for your detailed information. I was a bit bamboozled by this one and was not sure how set the transducer parameters. In the photo I had set the low & medium to the highest settings while trying to work it all out. I had trouble finding any info available on setting up. Attached is a photo of the tap settings on the DFF3 - hopefully I have those right. Any other tips on fine tuning you might add would be appreciated.

Cheers

Good afternoon Widget,

Tab (B) and Tap (B) are correct.

Get some screen shots on your next trip and post them to the forum, lets see what your looking at.

Kind Regards,

C-Bass
 
Hi C-Bass,

Great. Thanks again for your assistance. I will certainly take some screen shots on the next trip out and post them.

I was discerning bottom and structure at 600metres with a bunch of incorrect settings so it will be interesting to see the difference.

Cheers
