When I started out I bought a pair of used Cannon Mag 10s. The auto-stop feature was slick, but otherwise I did not like them! I sold them on again and bought a pair of brand new Scotty 1106s.
The final straw to get rid of the Cannons was this: the brake is controlled with a knob on the side of the unit....and the knob turns when the spool is turning (when retrieving) Several times I ended up having clothing or other items get tangled up with the knob, and the last event was my net getting tangled up while I was playing a fish solo. I couldn't get the net untangled and I lost the fish at the boat due to my confusion and frustration.
Besides the knob issue, my older Mag 10s had painted steel booms and while the paint seemed pretty good, there was little rust spots where the paint was scratched. The collars for telescoping the boom were fiddly and took a good grip to tighten them up. Not easy with cold, wet hands.
Also, the swivel base had a small tee handle that again wasn't great with cold wet hands.
I feel like the Scotty 1106 is a more rugged, easier to use unit, and spare parts are everywhere. The design of the Scotty seems crude until you use it and then it's just simple and tough. And, Scotty is a Canadian company eh!
That's my take on this.
