Tranducer Frequencies

Here is what I think I know and what I know for sure and I’m hoping to fill in the blanks. What can you tell me and have I missed anything?

HUMMINBIRD – almost 100% sure here
DUCER: XI 9 19 ICE (ICE 55) XI 9 20 (ICE HELIX) XI 1521 (ICE HELIX)
CONE: 9 19 20 60 15 21
FREQ: 455 240 200 83 250 130

VEXILAR – not 100% sure here
CONE: 8 9 12 19 20
FREQ: 200 200 200 200 ?

MARCUM – NOT 100% SURE HERE
CONE: 8 20
FREQ: ? ?

I think HB and Vex are right. I’m pretty sure Marcum is 200kHz, too. I think the LX7 also has a 50kHz setting for deep water, too. Lowrance is usually 83 and 200 kHz FWIW.

I had totally overlooked Lowrance. I’ll look into the LX7 deep water FREQ. Thanks!

I overlooked Garmin too. haha!
