The most dramatic difference between the Cannon mag20 dt ts and the Scotty is the price
After you add the ratchet rod holders to the cannon its at about 1400. ea.?
You could get three Scotty pro pacs for that. Unless there is something the cannon does the any of the other brands don't do, where is the justification in the price? After all there only function in to drop and retrieve a lead ball
I have had Cannons in the past (digi trolls and mag 10's) I'm glad a "Cannon rep" once told me when asked "what kind of rigger would you put on your new boat? he said " you kidding! Scottys! no lie!!
I once sold 4 used Mag 10's on Ebay, and made enough to buy 4 new Scottys. don't know what the attraction really is?? Must be the marketing i guess.
BTW I am a weekend troller, no sponsors.
