When you enter ecruteak city go left until you find a house go inside and you will find a man inside the house answer yes to his question and you will get an itemfinder try finding hidden items in ecruteaks burned tower
The itemfinder only works when there is a secret item around the surrounding area try using it where snorlax used to be after you woke it up and caught it/defeated it you will find an item called leftovers.
If you find an item with the itemfinder underwater, look for a patch of slightly lighter sand. go beside it, face it and press A. you should get the item in the sand. Hope this helped! Shinin
The itemfinder will point you in the direction of where hidden items are press A in that direction to find the item.
Find snorlax then stand in the exact spot where it was then use the itemfinder and you will dig up a item it is the leftovers.
Open every item lying around and make good use of your ItemFinder. You can also find them in the underground.
if you use the itemfinder there will be a blackglasses item. show it to him and he will say that those aren't his glasses, and he will walk off
You don't need to dig to get an item if the itemfinder responds. All you have to do is follow the signals on the itemfinder until you reach the spot where the item is. Then you press the space in front of you, or next to you and you should pick up the item.
Face the spot where the item is buried and click A, or use the Item Finder on top of the spot.
Press use to use the itemfinder and if it dings you have found something. Walk in the direction you are facing then use the itemfinder again. continue until the itemfinder starts shaking wildly and press A facing the spot and you will find something.
If the Itemfinder is shaking wildly in Pokémon Resolute, it indicates that there is an item hidden in the nearby area. Move around until the shaking becomes more consistent, which suggests you're close to the item. Try using the Itemfinder again to pinpoint the exact location where you can dig or interact to collect the hidden item. Explore thoroughly, as the item may be in a spot you initially overlooked.
Well firstly you obtain the itemfinder from prof oak's aide if you have about 30 Pokemon (I'm not sure) in vermillion to the far east. (The guard house if i could call it that). Now a fine example of using it is when your in a underground tunnel. First you go on your items menu and just click itemfinder then use. It would respond either "Yes itemfinder is responding" or "Nope, itemfinder isn't responding". How to get the item is quite simple, just face the ground where you think the item is and hit a and you should get a item, unless your wrong. I think the itemfinder has a range of four squares around you (one square is one of your steps)
The itemfinder item is not in Diamond/Pearl. But you can find items by touching the screen on either Poketch app 7 or in the Underground.
