• TDI EXTENDED RANGE

tdi_4color-LogoLG MEXICO UNDERGROUND & TDI EXTENDED RANGE DIVER

The TDI Extended range course we run here in Mexico provides training and experience required to competently utilize air for deeper dives up to 55 meters / 180 feet that requires staged decompression, utilizing nitrox mixtures or oxygen for accelerated decompression. Many student choose to combine this level when they look at moving into Trimix diving as in some remote destinations its not always possible to get helium mixes and their for requiring dives to be on bottom mix air for insurance purpose.

We can run extended range class in the ocean or one of the many cenotes here in Mexico.

At Mexico Underground we run Extended range class stand alone over 5 days or combined with normoxic Trimix diver over 7 days

The class fee includes logistics and training materials, we highly recommend purchasing and owning your own equipment for this level of diving but can rent equipment to students if required for use during your training.
