I have read countless threads on this discussion. Most of the debates are comparing a Vex FL28 to a Helix 7. The fishing community seems to be pretty well split down the middle. From a fish marking standpoint it would seem the Vex has the edge. The Helix comes with a GPS though which many people like. The Vex battery is much better than the Helix but apparently you can replace it with a better battery. FYI, I have had Vex for many years, have a 28 now. 10 years ago there wasn't a debate as the Vex was hands down the best but I think the graph world is catching up.
