Adventure caching

[NordieBoy]

Ok...
Anyone want to have a go at this?

Just place a plastic toy (or tupperware with a notebook and pencil) somewhere out on a trail (publicly accessable land please) and log the coordinates.

PM me with the coords and I'll add them to this post and to a GPX file for each cache.

Next person to find it does the same...
I'll put the person who has placed the cache after the coords.

Cache#1 (S 41 15.931 E 173 17.583) NordieBoy

Was wondering how long it would take for you to start this thread. I need a bike first :D

Cheers R

[NordieBoy]

Had to find a suitable container, pad, pencil...

I may move it from it's first resting place myself if it dosn't go in the next few days :D

Oiii! My globe doesn't do little numbers, I've got the equator and two tropics so far, am I getting close?

Two hemispheres...

Does it let you zoom in on my letterbox?

The zoom function round here is my glasses and I can just about make out the south island if I squint, so no, your letterbox is probably safe.

[Howie]

well I'll be in that area in the next couple of weeks, but don,t have a GPS yet, so no good me finding it.

A huge technology jump...I used Google earth and either your letterbox is on the footpath / road edge or you all drive funny down there. I have to admit the resolution was a bit off, as that bit looks grey and pixelated mostly, but your roof needs painting and the lawns are shocking.......:whistle:

Is there a prize involved?

[JATZ]

I was going to say, you don't go far from home Fran.

[NordieBoy]

My GPSd had an 8m margin of error when I grabbed the coords.
The roof was painted 3 years ago and yes, the lawn does need mowing.
The picture is from 2 years ago though...

It'll get put up the Maungatapu Saddle up a tree out of reach of you shorties if you don't settle down.

Nordie, I note you mention the GPS error and wonder how much of an issue this is? I recall that we have a constant issue with this at sea (using chartplotters) and the error there can easily be a 100 metres or more at times so how do you refine your search for the cache if there is the possibility of such an error?
Now, I know all about the evil american military messing with the satelites and the supposed error we should get but I have seen some huge errors (aforementioned 100 metres) and thats using new, Raymarine gear which ain't cheap.
So, do you have further clues to pinpoint the cache or what?

Maybe I better read the geocaching thread....

PS, nice place to live Nordie, we were down there last summer and stayed round the corner from you!

Hope Nordieboy doesn't mind me answering here

Well of course they are their satellites so guess they can do what they like really...
The deliberate error that used to be introduced goes by the term of "selective availabilty". Everything you need to know about the operation of GPS is pretty much covered here (http://en.wikipedia.org/wiki/Global_Positioning_System) If you scroll down that page you will find a section on Selective Availability.

This was turned off on 1 May 2000 and is no longer an issue.

My own experience of finding just over 2000 geocaches now is that about 90% of the time my GPSr will get me to within 3 metres of where the geocache is. Variations exist depending on how well the reading was taken (best to select "average" and wait at least 200 readings), the terrain (say reflected signals off nearby rock faces), visibility of and hour to hour variations in the satellite constellations. If it is more than 5m out then almost always the hider stuffed up on taking the reading. Pretty accurate huh?

From there it is either using a hint (e.g. "base of biggest tree") or your intuition as a finder, thinking about where you yourself might hide it, or experience of previous finds. Failing all that then a good old fashioned grid search.

what a great idea..how about a notebook in a sealed container.
Everytime it gets picked up..the finder signs it.
and so on..see how many KB sigs. can get in it.
have to get a GPS first...


And another bike.............

Ummm...
That's what Cache#1 is :D

There's an encrypted "hint" on the cache pages that you can click on to get the hint.
Once you start thinking like a cache placer then it's easier...

Ahhh, but I didn't live around the corner from me then either :mellow:
