Thanks to its \u003cstrong\u003e5W transmission power\u003c\/strong\u003e, your vessel is more visible to other vessels and shore stations, even in busy waters. The transponder reserves guaranteed time slots in the AIS network, resulting in more reliable and frequent position reporting, especially at higher speeds.\u003c\/p\u003e\n\u003ch4\u003eChartplotter with AIS overlay\u003c\/h4\u003e\n\u003cp\u003eAs a chartplotter, the ONWA KP‑25A offers a clear \u003cstrong\u003e5-inch TFT color display (800 × 480 px)\u003c\/strong\u003e with excellent readability in sunlight. AIS targets are \u003cstrong\u003eprojected directly onto the chart\u003c\/strong\u003e, allowing you to see at a glance where other ships are located and how their course and speed relate to your vessel's.
