The Dominators are iconic, and expensive to maintain and operate. Each of them is currently sidelined for extensive repairs, or in agreements for use with local weather stations.
But there’s another reason that they’re not on chases - their design is built around Reed’s old instrument deployment model: park in the path of the tornado, anchor to the ground, have the tornado hit directly, and launch probes from the inside of the vehicle into the updraft.
After years of work, Team Dominator has found methods with higher success rates which they use today, which don’t require the tank design. Additionally, Reed chases just about everything, and often flies to a target area, then rents a vehicle. When not renting a car, Reed uses Dominator Fore.
