Just curious how many use a portable fresh water cheapy fish finder?
I think I should get one because I need all the help I can get out there

. Would be cool to see nugs of Trout and structure in lakes instead of fishing completely blind like I have been.
What kind is good for CHEAP. Pink pickle warrior help?
Also people who fish the same lake all the time do you guys ever slowly build your own top secret structure with cement blocks or something and mark it on GPS and continue to build it over the years.
