These two courses are similar in their nature but have slightly different intent and application. Tek Lite Essentials would be best taken by somebody who either wasn't sure if they wanted to pursue technical diving and wanted some insight, or who was actually planning on taking their first course, such as IANTD Advanced Nitrox, and wants to be well prepared.
Tek Essentials is aimed at people who are already certified tech divers and need to review what they have learned before prior to taking a higher level course, perhaps after an absence from diving.
You will review and increase competency with your existing skills, as well as learn new skills which are applicable to more advanced diving. Through class discussion, land based drills and waterwork you can expect to :
Note: As with other IANTD programs, the diver must complete and pass the written examination, complete all open water requirements efficiently and safely, and meet all criteria on the final Course Evaluation Form in order to be certified.
You will find details of what is included and not included across all IANTD courses on the Overview page.
The IANTD Essentials courses are taught in double tanks or sidemount depending on your needs, with the instructor using the same equipment to ensure clarity of skill demonstration. The manual is available in pdf format.
These courses can be taken as stand alone programs or combined with actual technical courses.
For Tek Lite Essentials allow two days if you have previously completed Recreational Essentials Diver, or three days if you have not. For Tek Essentials allow two days if you have already taken Tek Lite Essentials, three days if you have not.
When combined with a higher course these will normally add two days to the total training time. For example Tek Lite Essentials with Advanced Nitrox, allow six days altogether rather than just four days for Advanced Nitrox only.
