A Digital Dive (デジタルダイブ, Dejitaru Daibu) is a method of transporting to the Digital World.
DATS utilizes Digital Dives to return the Digitama of Digimon that appeared in the Real World, back to the Digital World. Later on, the Tamers themselves alongside their Partner Digimon utilize a Digital Dive to go to the Digital World themselves. At the end of the series, all the Digimon and Daimon Masaru utilize a Digital Dive to go to the Digital World as both worlds became separated.
As a reward for saving the Digital World in the past, Mameo is rewarded with the power to Digital Dive, which he can use to visit not only his own Digital World but the Digital World of other Universes. He uses this to visit -next 0rder-'s Digital World.
