What is TVG?? (Time Variable Gain Explained!)
Вставка
- Опубліковано 10 вер 2024
- In this video I explain what Time Variable Gain is (TVG) and how it effects your sonar picture!
A lot of people will tell you to set it at "Low" or "Off", but not many people can explain WHY!
There's not a ton of information out there to explain this vaguely covered topic, so I found as much as I could and tried to make sense of it. Different brands of fish finders might calculate TVG a little bit differently or have more customization on how to adjust it, but in the end, they all produce similar results.
I want to add this disclaimer: The information presented in this video is MY interpretation of the vague info I could find online. That said, it makes sense to me, and I think it's pretty accurate.

Thanks so much! I'm happy to hear from someone who would have much more experience in that field than I approve of the video! I have quite a bit of RF experience, but it's not from a marine point of view, but I guess RF is RF is RF!
Does tvg work the same with chirp?
Now thats a good question and I don't know the answer. In theory I can't see why it would work any different. All CHIRP does is use multiple frequencies within a certain range to draw the image on your screen, so my guess is that yes, it would work the same with CHIRP.
