There has been mention of the Scotty manual or electric downrigger being a pain when paying out line. Due to the breaking system. I own a Scotty electric and a cannon manual versions. Have used Penn Electrics. I take both out fishing with me. But one is a back up when I solo fish. I use the Electric one exclusively. Yes the line can rap the spool, yes the brake line pay out brake takes some getting used too, but is quick to master. The Scotty Electric has a adjustable brake for the size of weight being used. So the brake will not slip out line when the ball is at depth. But will slip, as designed, if snagged on something. The manual version of Quad's, I don't think has the adjustable brake tension knob, but did have built in drag like a reel would. I bought my Scotty used. Had no idea what kind of warrantee it had. Called John's in Everett for the repair, after I owned it for 5 years. Asked how much to expect and when to pick it up. I think 4 or 5 days later it was done. Repair was free, lifetime warrentee. I had a faulty up switch. Under the lid, there is a comical, emergency handle for manual cranking the Electric model. I would not want to have to use it. Luckily the switch would always finish the job with minor monkeying.
The Penn's are nice. Heavy duty. But not as popular. Not to certain there is local authorized repair services, like Cannon and Scotty. I wouldn't hesitate to purchase a Scotty or Cannon again. But the Penn appeals to a eclectic group.
