Out on the water and your heading's a guess? That 2° drift adds up fast when you're navigating by feel. This Jaycar 200 Series compass gives you a steady, readable heading in fresh or salt water. Vibration-dampened capsules keep the card stable. The 65mm dial is marked in 5° graduations with individual balanced dials for precision. 12V red illumination means you can read your bearing at night without washing out the whole cabin. Bracket or adhesive pad mount – whichever fits your setup. Adjustable sun visor handles midday glare. 136(H) × 113(W) × 94(D)mm, so it slots into tight dashboards without a custom bracket
