While playing, keep looking at the map for key points,such as the lighthouse, islands, etc, and line them up with the same points on the map. It will help you out.
Some other good tips from the DayZ Wiki
The Clouds in Chernarus always travel from the West to the East.
- Zombies will always close in and attack the closest player, and will change targets if another player is closer to them than the original target
- Zombies are not socially active, or grouped, so aggroing of one zombie will not cause others to aggro
- Zombies can be lost by breaking their line of sight, but will continue to investigate player's last known location and the area; jumping into prone after going out of their sight can lose zombies, especially during nighttime
- Zombies stop chasing players when they are more than 300m away
A network of high voltage power lines near the Topolka Dam.
Power lines are a way to navigate Chernarus. The network consist of power plants, and high voltage transmission lines (the really tall ones) which go across the entire country-side.
The network goes along the coast between Solnichniy, Elektrozavodsk, and Chernogorsk. There is a three-way junction at Chernogorsk which then goes inland north-west to the Zelenogorsk sub-station, and then cuts east across Stary Sobor and Novy Sobor all the way to Berezino on the east coast.
I hope this helps!
