Explore further with TDI Cavern Discovery

There’s a cavern, I want to look in there!
The allure of a new environment is tempting, especially when you are diving in clear water and it appears “easy” to just poke your head in. Let’s face it, divers are explorers and adventurers – just poking our head in to see is not going to be enough. Don’t do it unless you are properly trained or have a TDI Cavern Discovery Instructor with you.
Who should I get to take me in there?
Locate a TDI Cavern Discovery Instructor at www.tdisdi.com to take you into the cavern zone. Caverns can be misleading and what seems like an easy dive can turn dangerous very quickly. A TDI Cavern Discovery Instructor can introduce you to the cavern and show you all its beauty.
What if I liked the Cavern Discovery dive?
Of course you did – it was a new and amazing adventure! Your TDI Cavern Discovery Instructor is also a TDI Cavern Instructor; that’s what sets them apart from all other cavern guides. TDI Cavern Discovery Instructors have been trained by the best and put through a full vetting process. Be careful of “cavern guides” – not all hold the same qualifications. Make sure to check that they have been trained and have the experience. Rest assured that a TDI Cavern Discovery Instructor has both training and experience.
Why does this matter?
It matters because your safety is a priority at all times and your Cavern Discovery Instructor will help to minimize the risk involved with this type of experience. You will be accompanied by someone that will reduce the impact that divers have on the caverns and surrounding environment. It also matters because if you want to move forward and take the TDI Cavern Diver course, you already have experience with your soon-to-be instructor. What better way to see if cavern diving is for you and if your instructor is a good fit?
What’s next?
Go to www.tdisdi.com and find a TDI Cavern Discovery Instructor at your destination. Contact them, arrange some Cavern Discovery dives and get your TDI Cavern Discovery Experience Card now.

Nauticam announce NA-A7C Housing for Sony a7C Camera

Sony’s latest full frame mirrorless camera, the a7C offers the underwater image maker one of the most compact and travel friendly full frame systems available on the market today. The a7C features Sony’s latest stellar autofocus and a much improved battery life thanks to its use of the larger Z series battery. The BIONZ X processor delivers superb low-light performance and faster image processing. For video shooters, the a7C features internal UHD 4K capture in the wide-dynamic range HLG image profile at up to 30p.
Nauticam has housed more mirrorless cameras, and more Sony E Mount cameras than any other housing manufacturer. This experience results in the most evolved housing line with broadest range of accessories available today.
Pioneering optical accessories elevate performance to a new level. Magnifying viewfinders, the sharpest super macro accessory lenses ever made, and now the highest quality water contact wide angle lenses (the WWL-1B and WACP-1) combine with the NA-A7C housing to form a complete imaging system.
Nauticam is known for ergonomics, and an unmatched experience. Key controls are placed at the photographer’s fingertips. The housing and accessories are light weight, and easy to assemble. The camera drops in without any control presetting, and lens port changes are effortless.
NA-A7C features an integrated handle system. This ergonomic style provides exceptional control access, even with thick gloves, with ideal placement of the shutter release and a thumb-lever to actuate the AF-ON button from the right handle.
Nauticam build quality is well known by underwater photographers around the globe. The housing is machined from a solid block of aluminum, then hard anodized making it impervious to salt water corrosion. Marine grade stainless and plastic parts complete the housing, and it is backed by a two year warranty against manufacturing defects.

What are the next generation of ocean stewards doing to protect our Blue Earth? Join us as we find out by speaking to Lauren Brideau, a recent graduate of Southern Connecticut State University. Lauren started as an undeclared major but soon found her calling, now she is part of a research team conserving life below water.
