Aeris 750GT Dive Computer Owner’s Guide

Description

This PDF owner’s guide is for the Aeris 750GT dive computer.

Aeris 750GT Dive Computer

Your Aeris 750GT is a two component, hoseless, integrated system that consists of a computer Display Module and a radio frequency Transmitter that will be installed into a high pressure port of your regulator first stage.

The Transmitter sends tank pressure data to the Display Module via a low frequency signal. In addition to nitrogen and oxygen loading data, breathing gas consumption is calculated and displayed in graphic and alpha/numerical formats on the Display Module’s screen.

The Display Module can also be used without the Transmitter as a stand alone, non-integrated computer, and will retain full use of all functions except those related to tank pressure.

Your 750GT presents the information that you need before, during, and after your air (or nitrox) dives using an intuitive combination of easy to read displays and unique identification icons. Tissue loading of nitrogen, accumulation of oxygen, ascent rate, breathing gas consumption rate, and breathing gas time remaining are presented as segmented bar graphs beside color coded reference indicators that bring quick focus to these important status displays.

As you progress through this instructional guide, you will become familiar with all of the unique functions and features available and see examples of the displays that you could expect to see in the various operational modes. Refer to the Glossary of terms in the back of this manual, and keep the waterproof Review Card handy during your dive trips. Although it will require an initial investment of time to become acquainted with the various icons and bar graphs, you’ll soon agree that the 750GT is easy to understand and use.
Remember that the rules you learned in your basic scuba certification course still apply to the diving you will do while using a dive computer – some will become even more important. Technology is no substitute for common sense, and a dive computer only provides the person using it with data, not the knowledge to use it.
