Hi ... have just come across a problem with datums new to me.
Some of my current Raster 250K maps USING OziExplorer show datum as GDA 94 [1994] and my GPS [Lowrance Map 100] utilises standard WGS 84.

The Raster map data advises that the HORIZONTAL Datum IS EQUIVALENT TO WGS 84. Taking a known point on both maps, there are minor differences in 'points of a minute' positioning.

QUESTION....... does this mean that WGS 84 and GDA 94 are equally accurate in my reckonings ......... bearing in mind the comment above " IS EQUIVALENT TO!"

Am currently using this info to locate/identify potential gold bearing locations, for detecting,thusly accuracy is fairly important to me.

Or does this mean that a more up-to-date GPS is called for?

And no ...... if I tell you any specifics on the said locations, I will have to kill you !!!

There must be a few members in this field, with the neccessary skills/knowledge.
