Big ships broadcast their identity, position, and course over AIS — every professional vessel is required to. The Quark-elec QK-A026 receives both AIS channels at once and pushes them over WiFi to nav apps on your phone, tablet, or laptop. On a small boat, that means you see the container ship before it sees you — in open nav software, with no subscription.
In stock direct from the manufacturer, and a quiet favorite of the marine DIY crowd.
Who should buy: coastal sailors, kayak fishers, shore-station hobbyists. Who shouldn't: lake-only boaters — AIS traffic is thin inland.
