These are limited edition (only 300 made) Divesoft DNA "Love Edition" oxygen analyzers. Brand new, in the package... never used! The DNA is a fantastic analyzer that utilizes the Divesoft app for monitoring and reading your oxygen content. Super small and compact, it's a great way to check your gas on the fly before splashing. The DNA uses standard R22 molex cells, one of the most common cells found in CCR diving. Recycle cells from your CCR buddies!
