So I found that in looking into fish finders I see some have the traditional black pixels which I am not interested in. Others have colour pixels which help with water temp, bottom type etc.. And then I find another type which has almost a picture...
I found this model which shows the both the colour pixels and also the picture type..

What are the benifits of the picture type screens? like the type the model I list has..
