Serious ice-anglers demand a mobile carrying solution from their sonar that adds features, not weight. MarCum's Roamer Shuttle is a semi-rigid case that shaves heft while highlighting innovative functions like a cable management wrap in its own compartment, tackle and tool storage, all in a ruggedized soft-pack and shuttle hybrid. The Roamer strips away the traditional gimbal style mount and the added weight by directly mounting to the slimline molded interior of the pack itself. When equipped with a MarCum Lithium LiFePO4 battery, the roamer excludes unnecessary hardware often found in existing shuttles, allowing anglers to enjoy up to 30% weight savings from traditional packs. All of which makes Roamer the lightest, highest functioning, best-engineered case on ice. Fits all MarCum traditional (i-series & M-series) flashers & Vexilar flashers.
