Hi. Nice video!
I have dual Evo3 S units networked together using the TM275LHW on Starboard side and A/I 3/1 on Port side.
With the wide 25 degree angle cone of the 275, how do you know where the fish are located with such a wide constant cone angle when they appear on the sounder screen?
For snapper fishing in shallow depths between 10-25m, how should I best use my Ducer/sounder setup configuration?
How does the narrow cone angle of the L (of the 275LHW Ducer) compare to say the L of the TM 265LH Ducer - when seeking good bottom structure and fish definition near bottom?

nice very instructive video, I wanted to ask you for some advice, as regards trolling live snapper on depths from 40 to 90 meters what kind of frequencies should I use? high? medium? low?, thank you

[@DeanSilvester]

high will give you better target separation to be able to identify fish in the bait

What transducer are you using?

SS175L and SS175HW mate

Hello, do you think I can have fish detection in 500 meters with this equipment?
-Simrad s5100
- airmar r109lm 2kw chirp
- nss evo2

Yes that would work but they don't recommend the 109 as its not an approved transducer
