Manufacturer: Dive Rite
Model: O2ptima FX version Rev D / DIVA Extreme
The DiveRite O2ptima rebreather meets the key features of a Type T rebreather and has successfully undergone a set of minimum WOB (Work of Breathing) breathing performance safety tests in line with the CE Standard (EN14143). We have checked the Type T requirements against the O2ptima rebreather’s performance and found that they meet PADI’s Type T standards in full.
To be added to the O2ptima to meet Type T requirements: Golem Gear Shrimp BOV

Great CCR. Very well built and great trim and buoyancy characteristics. For those looking for more information or training, contact me.
The new Rev D Primary display is excellent with many built in features. The newly designed DIVA allows for PO2 information and HUD Decompression. Small breathing loop give great response. A very well built machine….Good job Lamar, and Kevin for the electronics !
Does that mean that the Optima unit underwent all the full CE testing with the Golem Gear Shrimp BOV fitted?
Great! One the best CCR to Overhead enviroment or decompressions open water dives. The REV-D and new DIVA is amazing !!!
That is cool! Eduardo I agree!
So is this CE tested? The post doesn’t specifically say so, just that it’s been through test equivalent to EN14143?
