Another piece of equipment
with limited use that takes up space,must be maintained etc, etc. etc..
If you are sailing along, I find it is reasonably accurate to just sight over the compass that you are already staring at. Furthermore, your steering
compass is already the best compass on the boat with known deviation and proven reliability
(it got you there didn't it?). Compass mounted on a binnacle is easiest but my current
boat has dual bulkhead compasses and I can contort my head
around to get a good bearing on things behind.For super accuracy especially in rough conditions ,Just put ships nose on any point and read off your steering
compass, way more accurate than any handheld when the deck
is pitching and spray everywhere.
FWIW: my dated garmin GPS
(475) has a pointer that you can use to get an instant read out of any identified object on its chart.
