So I'm pretty new to kayak fishing but have fished since I was a kid. I recently got a cobra fish n dive and I really like it because I can carry everything, be super stable and get a great workout because it paddles like a barge. I have no electronics on it as of now and am looking to add either a FF or bait tank. I'm on a very tight budget due to no job and being in my internship for paramedic school. For those of you guys who have these things which would you add first and why. Also maybe some recommendations?
