Lots of Technology
A GPS was the final backstop for navigation. While its accuracy is fantastic, it's a nuisance to use because it requires a hand to hold it clear of the body so it can get satellite signals. Other equipment included a mountain radio so we could get weather forecasts and provide information on our location, and we also had an emergency location beacon if we ended up in serious trouble. It's a far cry from the Maori travellers who explored this country, and from the Europeans who followed them - like Charlie Douglas and Arawhata Bill.
