Tucker uses his PDA in "Parental Bonding" to go through a list of girls at Casper High School that he could ask to the dance. In "One of a Kind", Skulker takes one of Tucker's PDAs and integrates it into his armor, making him more efficient at the cost of being bound to Danny's schedule.
The trio uses Tucker's second PDA to track where Skulker is going to appear based on the schedule, and they set a trap for him. After they ambush him, Tucker uses his PDA to send commands to Skulker's suit to make it do random activities so he can't fight Danny.
Yet just when Tucker is about to shut down his armor, Skulker shoots the PDA out of Tucker's hand, pinning it to a tree with an arrow. This causes Tucker to complain that he had four more payments on that PDA.
In "My Brother's Keeper" Tucker shows Danny digital pics of him in his baby suit which he doesn't find it funny, then Danny shows the digital pics although Tucker was planning on deleting them but Danny was glad he didn't.

In "13", Sam tells Tucker to search about Shadow on his PDA when Kawn grabs it and fools around with it then Dash says he does that a little too well making him scream saying techo-geek is contagious. and run off. At first Tucker decided to change his image and he gave his PDA to Sam because everybody kept calling him a techo-geek since he carries so many technology around and he stomps off but luckily Tucker decided he doesn't like changing his image anymore. Dash and Kwan told Tucker that they're going to stop making fun of him and go back to teasing Danny from now on making him glad. When Danny asked to borrow his PDA for a new image, he tells him to get one of his own.
In "The Ultimate Enemy", Tucker attempts to hack into one of Clockwork's medallions with his PDA, to no avail. When Skulktech 9.9 appears and fights Danny, Tucker uses his PDA to hack into their suit.
In "Beauty Marked", Tucker's PDA loses power as he and Danny enter Aragon's kingdom, which proves to be an anti-technology zone. However, Tucker later praises his PDA when it still proves useful, as he throws the device itself to stop the Archer Ghost and the Executioner Ghost.
In "Flirting With Disaster", Tucker was holding and hugging his PDA after having another set of rejections from a couple of girls.
