Dave has been diving in HECS Stealthscreen wetsuits since the ‘beginning’ and was test pilot for one of the very first HECS prototype suits. Since then HECS Stealthscreen wetsuits have gone into production and gained a huge following worldwide for their innovative technology and high quality. Incorporating the ‘Faraday cage principle’, the HECS Stealthscreen suit contains a conductive carbonfibre mesh that neutralises the human body’s electrical fields (generated by muscle movement) allowing a closer approach to marine life. HECS wetsuits are made from premium quality Yamamoto neoprene with a Titanium Alpha layer (40% warmer than other neoprene of the same thickness) and are available in Black, Multi-camo’ and Bluewater, in 3mm, 5mm and a custom-made 7mm option.

DA: “If you haven’t yet heard of HECS, the theory behind the HECS fabric is that its carbon grid masks the electrical signals generated by muscle activity – something all living things (including divers) produce. Obviously marine species have other senses too, fish for example can see, smell, hear and feel vibration, but as it is cumulative sensory input that dictates the behaviour and reactions of most species, the less input they receive the less reason there is for them to flee or change their behaviour. My goal is to get as close to marine life as possible to film natural, undisturbed behaviour, so it makes sense to take advantage of any new innovations that can help me either be ignored or regarded as non-threatening rather than being perceived as a potential predator. The HECS technology isn’t a ‘magic invisibility cloak’, but by masking your electrical signature it does eliminate one of the sensory signals that determine how close an animal will let you approach. As well as the HECS ‘Stealth technology’ these are the warmest most comfortable wetsuits I have dived in bar none”.
