The 48 NM range and 60 RPM rotation make it well-suited to fast-moving vessels where target update speed matters. Scan Averaging is particularly valuable in steep chop or following seas where sea clutter would otherwise obscure close-in targets. It connects to any Garmin GPSMAP or echoMAP chartplotter via a single cable, and supports dual-radar mode when paired with a compatible Garmin MFD — a common setup for vessels that want overlapping short- and long-range coverage. Boaters with limited arch space who still want xHD3 performance should consider the \u003ca href=\"\/products\/11131370930212\"\u003e18\" version\u003c\/a\u003e instead.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51232999178276,"sku":"322-0100284200","price":4194.85,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/322-0100284300_a5b35e7e-0917-4352-8355-e425f414e24e.jpg?v=1786151956","url":"https:\/\/marisolmarine.com\/products\/garmin-0100284200-gmr-xhd3-radome-24-322-0100284200","provider":"Marisol Marine Company","version":"1.0","type":"link"}
