Why do people use fish gps systems to catch fish?
because they mark under water and or deep structure like road beds and creek beds etc. they use them because if your not at the right spot then you might not catch the quality fish and it is a lot less time consuming then going to a general area and graphing it with just a fish finder to find the spot. Gps’ generally get you within 10′ from the area marked in the fish finder.
