Of course questions I have.The boat your tracking is 270 and the largest range is 200.Do I fudge the 200 line and add 1/3 of the speed shown since 70 is 1/3 of 200.LMAO if you understand that. |
Hi Mate, easiest method would be to use the 150M scale and just double the value.
Ie: if it took 55 seconds for a vessel of 300M to cross the crosshair, then reading the time of the 150M scale would give 5.5Kts.
now double that to convert to 300Ms gives 11Kts.
Scales are very versatile that way.
