Go to the ABBANDONED SHIP and go up/down the first set of stairs in the ship thengo into the door in the middle at the bottum. Dive into the water and go into the entrance. then dive up and you will came to a building with 6 doors first go in the third door and there will be something shiny click on it and you will get a key. do the same thing with all the other rooms. when you get the sixth key first go in room five there should be around four shiny things go into room six now and go left into room five go get the shiny thing at the far left and it will be the key to room 2. go in room 2 and there will be a pokeball, it is the scanner.
You find it in the abandoned ship.
there is no scanner on fire red/leaf green. Only on ruby, sapphire, emerald
you get the scanner on the abandoned ship.
actually the scanner is ina pokeball in rm 2........
Once you get the scanner, go to slateport and find captain stern, he will trade you a hold item for it.
u surf to route 108,and then go to the abandon ship.you will find a scanner in room RM2.and then,u trade the scanner with the capt.stern.he will say "oh?your name,that item you have...that's a scanner!bla bla bla...and you choose on.that's all......) == (this is for ruby, Sapphire and emerald too)
The scanner can be found in the abondand ship on route 108 in Room 2... but first you must have a Pokemon that can use the dive hidden machine and you must find the room keys to the other rooms that are lying in the rooms. Its is an easy process
the abandoned ship in emerald is a ship that halfway sunk into the sea a little while earlier in the game. you can find ice beam and rain dance in there as well as the scanner and it is a good place to train your guys
One can find Brother's scanner range in the User's manual that comes with the scanner. Once the scanner is installed the computer, one can also find the range in the scanner's setting.
That's how you get the items in the first place by giving capt stern the scanner.
in one room on the abondoned ship, you can dive, then you have to enter rooms and find keys, eventually you will get the scanner in RM. 2. Take it to Cpt. Stern, and he gives you a deepsea tooth or scale. They evolve clampearl through trade into huntail or Gorebyss
i think you get it from steven.If now then sorry i dont know. :( <-----That's not right. You have to get the scanner first in the abandoned ship and you trade it to Captain Stern for a deepseascale or a deepseatooth.
