Rating: Nice compact octo
Reviewer: Eric P.
This octo is great. Nice compact design, lightweight, and highly visible. The best part is the omnidirectional design which means that there is no "up" or "down". I also like that Mares supplies a custom holder clip that securely fastens the octo and prevents any debris from entering the mouthpiece. Great price for a good piece of equipment.

Rating: Review of MV Octopus
Reviewer: Constantine P.  -  View all my reviews
I was very happy with this regulator overall. I have a Dacor Viper as my my primary regulator so this was an easy decision. The one thing I did not like was that it tended to free flow when I had it attached to my BCD but that stopped when I diconnected it from the octopus holder.

Octopus MV
Compact and lightweight

• Sturdy and durable

• Hi-Viz yellow cover and hose

Its limited weight, minimum space requirements, and symmetrical and compact shape, make the MV the ideal octopus. Easy to use on the right or the left, it offers great dependability and natural breathing thanks to the NBS (Natural Breathing System).
