"free dive mode" ???

[Snodger]

I'm shopping for my first computer and while researching here and on the web I noticed the following in the description of the Oceanic Geo:

"...the GEO is the first Free Diving Computer to calculate and track Nitrogen Tissue Loading, allowing you to switch between SCUBA dives and Free Dives on the same dive day..."

since I seem to find myself mixing free diving with scuba dives when I'm on dive vacations, I'm wondering if anyone can help explain (or point out other resources I can check out) how this type of feature works, if other computers have it, is it really a necessary feature or just marketing hype?

thanks

I have been using my Aeris Manta which essentially is the Oceanic Geo since February for both freediving and scuba. There is a thread on here somenwhere where a full review was posted also.

I don't have any idea if it's hype or not. However, somewhere here on SB, someone once pointed out that microbubbles might be made worse by the repeated and rapid ascents when freediving after scuba diving. Conceivably, an RGBM-based computer which tracked this without adding to your nitrogen loading might have some benefit. This might be something to keep an eye out for in your research.

The Geo/Manta is not RGBM, it is DSAT based.
