A compass is actually quite useful on a heavily tree lined course Lubin. If you know which way the wind is blowing you don't need to guess from a secluded area.

Forum needs more banter.
If anyone on a golf course, playing golf, needs a compass to determine which direction they need to hit the ball then they need to take up lawn bowls.
I know this is regurgitating previous threads, but it's still very topical.
I was given an example along the lines of this: a golfer playing at a course like Augusta (tall trees lining every hole) on a cloudy day (can't see the sun). A compass would tell them which way north is, so they could work out which way the prevailing winds are blowing above the tree line.
IMO, the compass thing is a load of crap. I've been playing my home course for 20 years, and knowing which direction is North has not saved me a single shot in all that time.
Courty it won't make a lick of difference on your home track but I can tell you that over the last 3 years of adding at Coolum we lived off it (yardage book had north marked on each hole).
Forum needs more banter.
I don't know, but if there's nothing stopping north being shown on a yardage book (whether course issued or
DIY) I can't understand why they'd disallow compasses.
Don't you blokes know what an artificial device is yet?
Some compass applications also give wind direction and speed.

Does anyone know what spheroidal co-ordinate base is used when X company puts the maps into their data base. I'm presuming 90 odd percent are mapped off Google Earth which would more than likely use WGS84. That would translate differently to AGD94 (or AGD86, can't remember which is the current one) and you'd then get distance discrepancies.

If you start out depressed everything’s kind of a pleasant surprise.
WITB: stuff.
Haysey raises a good question... would it be legal to use a smartphone to view a PDF of said course guide?
I know that you know the science Kev but why are you saying it would be a problem? Most GPS units (non golf) can be set to different coordinate systems. As long as the app, or unit, was using the same as it was mapped you would be fine. Unless you are talking grid/plane distances here and since we are talking about 80mm per 200m I'm pretty certain that wouldn't help too many of us.As a side note you can get apps that display coords in MGA format (GDA94) that I have used to find permanent marks. Best I have had so far is inside a 1m diameter.
Have you tried setting a mobile phone to a different co-ordinate system?
I would have thought distance markers on courses would be derived from GDA (given the surveyor would effectively be working in that when setting out the course) and the golf GPS device would be in WGS 84
I thought the difference was more than that. There you go

But distance markers are relative to two points aren't they? In this case centre of the green. Therefore it doesn't matter which system any measurement is in because the 150m marker and the green would be relative to the other one only.
I think the old AMG coord system we used in Aus had a different centre of the system by about 200m to GDA and WGS84, but my same answer above would still apply.
BTW my grid/plane difference above is the diff. between grid coordinates from a GPS unit and what you would measure with a tape measure on the ground.
