At an early age, Grant Tobin was adopted into the Florida cave diving community. Learning the ways of the cave early on, shaped him into the diver he is today. An active member of the Midwest Underwater Explorers, a volunteer of the Wisconsin Historical Society’s Maritime Preservation and Archaeology Program, and he continues to find his way back to the Sunshine State to enjoy the overhead environment. In this episode, I speak with Grant about why he switched from the KISS Sidewinder to the Fathom Gemini, Sidemount vs Backmount rebreathers, advice for divers seeking overhead training, and much more. Please enjoy!**Grant did amend that a few current rebreathers do in fact ship stock with oxygen shutoff valves**Midwest Underwater Explorershttps://www.mwue.org/Karst Underwater Researchhttps://sites.google.com/view/karstunderwater/homeWisconsin Marine Historical Societyhttps://www.facebook.com/WisconsinMarineHistoricalSociety/Article by Grant TobinmCCR Face-Off: Gemini vs Sidewinder - InDepth (gue.com)
