Nah realistically I have a navigation app on my phone. But it definitely is not nearly as good as garmin. Except at the end of this season I found garmin’s navionics app and that works well. So really I do trust in garmin lol. That and God. Buuut garmin isn’t very cheap, so this video has some validity to it. Let me know what you guys use for nav in th comments, I want to get a chart plotter. I have a hummingbird fish finder but it’s like the smallest one. #saltwaterfishing #garmin #godsplan #bo
