I think I put my Oceanic on Guage mode once, and I think it stayed on that until it powered off. Could not get it back to scuba.Do you have a dive computer?
Some dive computers will do both FREE and SCUBA in the same day, tracking your nitrogen.
I've done a lot of free diving mixed with SCUBA diving. I simply change from SCUBA to FREE and off I go. You can see how the free diving actually affects your off gassing.

You should be fine with a good S/I. Also do a nice long safty stop on your last dive. That way you will be sure to off gas exess nitrogen. Have fun
Greetings funnyfish22 and We did precisely just what you are asking while on vacation a few years ago in Mexico. Our dives were fairly moderate and our computers were mostly clear. This after a long SI, lunch and little nap. We enjoyed a casual surface swim to a small reef with shallow free dives to 20' or so. It was very relaxing and super awesome. We actually visited this reef several days in a row which was interesting to watch the fish that called it home. Our nitrogen levels were always in check and one consideration is alcohol. We did not drink anything but water and juice till the evening meal and kept it to a minimum while we were diving. This was our practice until we were finished diving. Personally I would rather dive everyday morning and afternoon and snorkel / free dive when that was not possible. I could not get enough of it when I was there. Enjoy your trip and take every advantage to get in the water you can. Do not feel snorkel / skin diving is a slight I loved it and it added a great dynamic to our trip. It is fun to be out in the ocean just letting time pass and fish do what they do. No nasty bull sharks were seen, darn! I am to interested to be worried, my friends call me crazy.
CamG Keep diving....keep training....keep learning!
You folks are missing the point, it is not the nitrogen uptake during free diving that is the issue, it is bubble pumping. See this thread, starting with my post #18.GUAGE mode and FREE mode are two very, very different modes.
When the computers are in FREE mode, that sample ever second, at least, and once you surface that start a timer so that you can track you SI between free dives. Once you descend again, they start the dive again. In FREE mode they track your nitrogen loading.
Most computers will easily let you switch between FREE and DIVE modes throughout the day.
Most of us are familiar with GUAGE mode as your traditional depth and bottom timer. In GUAGE mode, they don't track your nitrogen loading.
Most computers will lock you out of anything but GUAGE mode for 24 hours after you put it into GUAGE.
