I used regular dipsys (001 - 4 1/8") and weighted mag dipsys (003 - 4 7/8") and have the depth charts laminated in my boat which I consult frequently. A friend gave me some regular dipsys with the aftermarket larger ring on them which basically converted them from 4 1/8 inch to 4 7/8 inch but without the weight. He glued them on bc he said that the rings have a tendency to slip off. Of course, I could change to regular rings, but would like them to function closer to mag dipsys. As they are, I'm guessing that they'll run to depths somewhere between the reg dipsy and weighted mag dipsy. The mag dipsy weighs 8.8 oz vs 5.8 oz for the reg dipsy with larger ring. If I add 3 oz of sinkers to the 001 w larger ring, I'm thinking that this should run at same depth as mag dipsy? Anyone tried this before? Thanks.
