Geez guys,I must be getting dyslecksic.I apologize for the way step 4 was written.It should state subtract the smaller from the larger bearings.I'll have to start proof reading these before I send them. -----Original Message----- From: David Weilacher [mailto:daveweilacher@EARTHLINK.NET] Sent: Tuesday, March 25, 2003 10:51 To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: Re: Distance off useing a hand held compass So you are arguing that if I can measure the distance I travel... If I were to take a bearing on an object then wait till the bearing changed by one degree, my distance off would be 360 times my distance travelled? At 2 degrees, I could multiply my distance traveled by 360 and divide by 2 for distance off? This is strictly a question. In no way is it meant as a comment or criticism. -------Original Message------- From: "Richard M.

Could you not just take a bearing, walk away from that point so as to keep the object more or less at right angles to your (perhaps slightly curved) path, and stop when the new bearing is 10 mils different from your first? That way, the distance to the object will be 100 times the distance you traveled ... barring local magnetic anomalies.
