If You're Skeptical, Read This First
If your electronics were dialed in and you were happy with what you’re seeing, you wouldn’t still be searching for answers.
I know how this goes. You’ve already:
1) Spent serious money on your fishfinder
2) Tried tweaking settings but you’re still not confident
3) Watched YouTube after YouTube and every “expert” says something different
4) Seen perfect demo screenshots online but your screen doesn’t look like that on the water
That’s exactly why Fishfinder Coach exists.
I’m on the water every week, guiding and testing on Garmin, Lowrance, and Humminbird units in real conditions, not factory defaults.
If you're skeptical, good. You should be.
Just know this, every single review on this site came from someone who felt exactly like you do right now.
When your screen finally makes sense, that skepticism turns into confidence real quick.
