TDI Helitrox in Malta: 11 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 6 publish course prices.
TecDiveTools lists 11 dive centres teaching TDI Helitrox in Malta. 6 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 11 of these 11 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 9 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

About the course
Helitrox teaches decompression diving using helium-blended breathing gases to manage narcosis at moderate depths. This course bridges the gap between air/nitrox and full trimix, introducing divers to helium's benefits without the complexity of deep trimix training. Graduates can plan and execute stage-decompression dives using helium mixes (up to 35% He content) alongside nitrox and oxygen decompression gases, to a maximum depth of 45m/150ft.
Students must complete 4 open-water dives (2 must exceed 30m/100ft depth) with demonstrated mastery of: helium gas physics and physiology, decompression stop calculations with multiple gas mixtures, proper equipment configuration, safe gas switches at depth, emergency procedures for decompression gas failures, and correct ascent with staged stops.
11 dive centres on TecDiveTools teach TDI Helitrox in Malta: Malta (6) and Gozo (5). Each is listed above.
Deep water close to shore and the protected deep wrecks make Malta a natural place for deep training, from decompression procedures to trimix, with the wrecks giving deep dives a purpose.
