GPS vs Knotmeter
I have an old signet knotmeter that has finally given up. I am tight on cash right know and am looking at replacing it with either a Gps or a Raymarine Knotmeter. I just have a couple of questions. I can''t afford both so. Is the Gps as accurate as the knot meter? I have heard that it doesn''t update very quickly as far as speed, Is that true. Is it possible to us the gps to trim for speed? I''m looking at the Garmin GPSmap76 or RayMarine knotmeter. Any help would be great. If I get the Gps I would plan on getting the Knotmeter in the future.
