The Hollis 321 Octopus Regulator is no longer available for purchase. We have 1x left in stock in store so once that has sold that’s it.
The 321 has been replaced by the Hollis 150LX Octopus. Retail price at the time of writing this for the 150LX is $499, so if you were looking for an octopus with Hollis standards of quality and realiability but at a cheaper price point, this is the way to go.
