Vexilars have a totally different display than the types you have now, visiting their website will show you what they look like. They are far better than the graph type for ice fishing mainly because you can adjust the sensitivity to allow you to see your lure as well as any fish under you. They also have an instant readout, I believe yours take a few seconds to show you a fish. When you see a fish come thru, you see where your lure is also and raise or lower it to put it right in his face. A couple of little jigs and you usually have a fish on the ice. This is especially handy when fishing for fish that usually suspend, like kokenee or crappie.They show water depth, but do not show the contour like yours, in a boat they would be great for jigging while sitting still, but I think yours would be better for moving around trying to locate schools or ledges, dropoffs, etc. When moving around on the ice you can check depth without drilling holes by setting the transducer on the ice and pouring a little water on it. This helps you quickly find channels, dropoffs and whatever depth you want to fish in. They are pricey, but Vex. has been around for a while and they make a good product. I've had mine for 13 years. You can get a used one on ebay, some come with a 30 day warranty. Hope this helps.
