Cannon is about #x the price.
I had 4 cannon's, and when the electronics corroded inside after about 5 years, they said they no longer made them, butthat I could easily bypass it the e-board and jsut have a up/down switch. A lotta good that does! Just makes the $1000 downrigger a $100 cheapie!

Cannon is nice in that you set "down 100" and it does that and auto-stops.

For a simple machine, neither is 100% perfectly engineered.
