Accufish

I have a TZT2+dff1-uhd and b275w transducer

The accufish and bottom discrimination feature is not lit up to select. I believe from other posts snips had mentioned this only works with b265 transducer?

I just wanted to clarify that my system will not have these options?
 
Calpolygeno,
Only the 265 series is in the UHD's database for the AF and BD modes.

It looks like the 275 series better matches the frequencies output from the UHD - will the 275's ever be added for AF & BD or is there something with the beam angle?

Thanks, Eric
 
Ericl,
Both functions use both frequencies, for ACCU-FISH mode having different the beam angles for the LF and HF is quite important to determine fish size. For the Bottom Discrimination mode the system is looking at the secondary echoes to determine Rocks, Gravel, Sand or Mud. A wider beam width on 200Khz means less returns (information) the sounder has to work with. There is going to be a meeting next year and I can ask this question for you.
