Its great for a guy in a ski boat who dont depend on the batteries as we do fishing.It would be partly dependant on your style, meaning do you fish a long day? Do you ride trolling motor hard with your style of fishing? I will say this, they pull on a battery real hard so keep that in mind.Also, if left in the sun, it wont bring the drink down to a temp anywhere like a bag of ice would in a cooler. I believe you would be happier, with a cooler and ice but it all depends on what you want.Good luck to you.
