LRT has conducted a
sport diver rebreather development program since 1982. LRT surveys sport
divers to determine "what the market wants". Prototype units were displayed
at the 1995 through 2005 DEMA trade shows. Two prototypes were field tested
as the "GATOR" and "PROBE", from 1996 to 2001. Over twenty of these units
were used in field beta testing in New York, Florida, Texas, California,
Hawaii and the far east. The "FROG" is the product that is the result of
this effort. LRT now have over 100 FROG units in service.
