Those are great reels for diy "magging" where magnets are incorporated into the side plate and they will cast really far without backlashing. The spool for magging a real has to be aluminum. The little knob is the adjustment.
I've included some reds I get in my creek. It's a 15 minute paddle and the fishing is world class. I only fish top water and it's too fun to describe.
I'm lucky to be able to fish both fresh and salt water whenever I want. The ice chest of catfish were caught with a guide. 4 hour trip. 71 catfish split between 4 people. Flounder and redfish came from salt water. If it swims, I'll fish for it. lol.
