Tools are of great importance in the game "Stalker: Call of Pripyat". Their search is optional, stalker technicians can work without them, but the most complex improvements to weapons and armor are possible only with a variety of tools.
Cardan Tool Set
After receiving the quest from Cardan at the "Backwater" location, when he asks to find various tools for him, head to the abandoned sawmill. Without engaging in battle with zombie stalkers, go around the warehouse building on the hill and go down to the detached destroyed house.
Run past the stalled truck and dive into the doorway. Shoot the zombies inside the house, then in one of the 2 rooms, find the stairs leading to the attic. Search the small room and take the tools.
Each technician needs 3 kinds of tools: rough work tools, fine work tools and calibration tools.
However, leaving the attic is not so easy. Zombie stalkers will gather in a bunch of shots and block the passage, preventing the player from leaving inaccurate, but dense fire. Break the boxes in the attic and get the grenades from there. Throw them into the cracks on the floor into the cluster of dead stalkers. When those are dispersed by the explosion, get down and run as fast as possible.
After that, you should visit the substation to the west of the "Circus" anomaly. Approaching it, you will stop from the menacing shout of the mercenaries entrenched in it. Agree with them, promising to bring food. In exchange for food, the mercenaries will let you rummage around in containers in the backyard of the substation, where, after a short search, you will find another set of tools.
Nitrogen Tool Kit
Going to the location "Jupiter" will also have to look for tools for a local technician named Azot. To do this, walk along the railway tracks to the south until you come across an abandoned electric train bridge. Climb onto the bridge and jump down the open sunroof. Run through the cabin to the vestibule, where you will find instruments on the floor. Having received what you want, jump onto the windowsill, sit down and climb out the window.
Another set of tools is located on the territory of the Jupiter plant. To do this, go to the "Concrete Bath" anomaly, where you will find the iron gate leading to the factory yard. After entering inside, move to the right multi-storey building, where climb to the very top. On the top floor in the right corner there will be tools.
The tools for each of the technicians are interchangeable. You can take the tools from the "Jupiter" location to Cardan at the "Backwater" location, and you can give the tools from the "Backwater" to Azot on the "Jupiter". This replacement will not affect anything.
Calibration tools
Having reached the Pripyat location, go north to the old building of the former KBO. Go to the second floor and search the shelves, one of which will contain tools. Take them and fight back or run away from the burer who attacked you.
Another set of tools is located in the south of the dead city in the basement of a department store. Climbing into it, you will be attacked by a flock of mutated jerboas. Disperse them in bursts and follow the fleeing monsters. After running after them into the closet that served as their nest, finish off the remaining rodents and pick up the tools.
