I agree – it depends. In shallow water yes, I fish the holes first. In 8 or 10 feet of water the transducer cone is pretty small and doesn’t show much.
There’s a lake that I often fish for suspended crappies. They are usually 20-30 feet down over 40-50 feet of water. They often school. Pretty common for me to just walk around with my electronics looking for the school before I fish on that lake.
I tend to fish most every hole for at least a minute or two on lakes I’m less familiar with, hoping to call nearby fish in even if they don’t show up right away.
