Hi everyone, as I'm sure most of you are aware I've recently invested in a GPS or to be precise a Garmin Etrex (the yellow one). After 12 years of using a sighting compass on Dartmoor, I decided to get with the times. The GPS is only for the occassional use, as I feel it takes a lot of fun out of the 'searching' part of letterboxing.
One thing I'm not to sure about is what the setting should be, I've read through the handbook but it's not that clear which one's I should be using for the moors. By the way, it worked ok yesterday on Dartmoor, shame it threw it down with rain most of the time though.
Ok, here are the settings I have got so far:
Position Frmt: British Grid Map Datum: ord srvy GB Units: Statute North Ref: Magnetic Variance: 004°
Are any of the settings wrong? I tracked a couple of boxes down with the GPS so everything seems to be working okish.
Thats interesting variance dont think my Garmin 12 has that on will have to check.
I use it for 8 digit boxes as well just add a nought to the back of the four digits then when you get there dig your compass out and check the bearings off the clue, (that might keep Nic happy )
Now a Sustrans Volunteer Ranger Group Coordinator on the Trans Pennine Trail
Thanks everyone, at least I know that I've got the setting correct!
I found it gets you in the right area for the boxes, but as mentioned I do prefer using my sighting compass, old habbits die hard. I think when it's foggy, or it's those boxes which no matter how hard you look you don't even find an empty site, the GPS will come off my belt clip.
