  1. Still available, and will throw in a free Ultralight tripod plate + mounts (retails at $185)
  2. Just wondering if anyone has had a chance to try our the AOI UWL-03 PRO lens yet? I'm in the market for a wet lens for gopro, but at more than double the price to the original UWL-03, I'd like to know if the PRO version is worth it.
  3. I have for sale a GoPro 10 in great condition. Comes with underwater housing, a set of three filters, two batteries + charger, and charging cables. The GoPro is in pristine condition, I haven't used it much and never used it outside of the housing. There are a few scratches on the housing, not on the lens though. Also a few scratches on the snorkel and dive filters, but the magenta filter is pristine. Asking $100 and I will include shipping.
  4. I have for sale an Ultralight tripod plate and 3 ball mounts, including all the screws. I've only used it a handful of times and is in very good condition. This is a very versatile setup and with the addition of a few clamps and arms, it makes for a great tripod. Retail price of the set is $185. Asking $100 obo. I will include shipping if you cover PP fees.
  5. I have a pair of Light & Motion SOLA 15,000 lumen video lights for sale. Bought new from Bluewaterphoto in May of last year, and only used twice, so they are basically brand new. Includes chargers and ball mounts. I'll pay for shipping if you cover PP fees. Retail price for the set is $2,300 ex tax, asking $1,700 obo.
  6. Like new, asking 50% of retail price, $120 net to me. I will take care of shipping.
  7. I spent the better part of a year in Mauritius back in 2010/2011, and did quite a bit of diving. I remember Passe St. Jacques, in the south close to Le Morne, was best for big stuff. Lots of current drifting through the pass in the reef, which attracted lots of sharks and eagle rays. If I would ever go back to the island, I would head straight there with a WA setup. Corsair Wall in the north was also very good for big stuff (huge schools of eagle rays), but hit or miss. Of course it's been a long time, so things might have changed... Back in the day there was also the Shark Cave at Round Island off the north side, but I never dove it since the sharks were not there at the time. It looks like they're back though, as tecdivingmauritius.com is offering it as a day trip. Might also be worth looking into!
  8. After selling most of my R5 kit, I still have a few miscellaneous items left: - Nauticam N120 70mm extension ring ($413 retail) - Nauticam flash trigger for Canon ($308 retail) - Nauticam zoom gear for the Canon RF 15-35mm f2.8 lens ($237 retail) - Sony Tough 256 GB CFExpress card Type B ($298 retail) - Circular polarizer filter for DJI Mavic 3 / Mavic 3 cine drone (accidentally bought the wrong one so brand new and unused) If anyone needs the filter, I'll throw it in with any purchase. All items are in perfect condition and looking to sell at 50% of retail price net to me. I will cover shipping.
  9. All the big stuff is sold. I will post some miscellaneous leftovers in a separate thread.
  10. @Mathieu Cornillon Unfortunately most of my pics are of archaeological remains! The best resource is probably the Scubaqua website, https://www.scubaqua.com/gallery/ @ianmarsh Thanks! Statia, Saba, and St. Maarten definitely have more sharks than the ABC islands. While this observation is not based on any scientific data, my experience after 15 years of diving on Statia is that there used to be a lot more sharks than there are now though. I'm not sure if human population size/density is the best indicator, although it must have some effect. For example, some sites on the British Virgin Islands have lots of sharks, and these are close to Tortola which is very populated. I guess it has to do more with how the marine environment is managed/protected. Maybe there are marine biologists here on the forum who can provide some insights?
  11. St. Eustatius, locally known as Statia, is located in the northeastern Caribbean at a stone’s throw from St. Maarten. While its neighboring island Saba is a well-known diving destination, Statia is often overlooked. I have lived on Statia on and off for the past 14 years and have spent a good 6 years of my life on the island. I’ve worked at the local dive center and have organized numerous underwater archaeological projects and exploration dives all around the island. As a result, I know Statia’s marine environment very well. I have also dived on nearly every island between Anguilla and Grenada, so I have plenty of comparative insights. Statia is one of those islands where time has largely stood still. It is not a resort destination. There are no casino’s, clubs, or shopping malls on the island. It’s a very laidback place, 8 square miles in size with a population of about 3,500 people. Everyone waves at each other on the street, people leave their homes unlocked when they leave, and cows, goats, and donkeys roam the streets freely. It’s quirky and not for everyone. If you’re after white sandy beaches and vibrant nightlife, don’t go to Statia. If you’re a nature lover and want to experience diverse diving, beautiful hiking on the dormant Quill volcano, and soak up some fascinating Caribbean history, this is the destination for you. Getting to Statia is fairly straightforward. You have to fly into St. Maarten first, and from there you either take a ferry or an 18-minute flight with Winair on one of their Twin Otters. There are several accommodation options on the island. If you want to be close to the water and right next to the dive center, I recommend the Old Gin House Hotel. If you don’t mind being further away from the water (a 10-minute drive), I recommend Quill Gardens, a Bed & Breakfast with a beautiful view that’s managed by a lovely Dutch couple who make some of the best food on the island. There are two dive centers on the island. The one I can recommend is Scubaqua (www.scubaqua.com). It is managed by a Dutch couple, Mike and Marieke, who have been on the island for 15 years. They are very passionate about the island and just really nice people. They train their staff very well and it’s a very good and safe operation. Check out their website and TripAdvisor reviews. As for the diving, it is very diverse, accessible, and uncrowded. All dive sites can be reached within 15 minutes from the dock. Most dive sites have moorings, but some are drift dives. The island’s main reefs are coral-encrusted lava flows situated on a flat sandy bottom, typically between 50 and 60 feet deep. There’s lots of life on these, typical Caribbean reef life with the odd reef shark and eagle ray passing by. These are very good beginner sites, but also great for photographers. My favorite site is one that I discovered several years ago with a ranger from the local marine park. It’s an elongated lava flow named Lost Anchors, after the five historic anchors that were lost on this reef in the colonial period. They are beautifully overgrown and add some history to the dive. Reef sharks are a regular appearance on the site, and you’re usually surrounded by several dozen big barracudas. It’s a more advanced site as it’s a free descent down to 80 feet and located quite far offshore where it can be choppy. Along the southern part of the island, bordering the dormant volcano, topography gets more dramatic. Here you’ll find steep drop-offs without a bottom, where it’s possible for anything to swim by. This is the most dramatic diving on the island, but not for beginners. Sites like Grand Canyon and Drop-off are not to be missed. If conditions are calm, the northern tip of the island offers some fun dives as well. Here you dive along boulder slides that end in a sandy bottom. Lots of life hides between the boulders, and around the rock called Gibraltar you have a very good place to see sharks as well. This is where great hammerheads sometimes make an appearance (far from guaranteed of course). There are several wrecks around the island as well. Two modern ones you shouldn’t miss: a 330 ft / 100-meter-long cable layer called the Charles Brown and the Chien Tong, a Taiwanese fishing vessel. Both were purposely sunk. The Charles Brown is home to a large school of horse-eyed jacks and provides lots of good photographic opportunities. Some parts are covered in lots of black coral. The Chien Tong is a fun dive during the day, but I recommend diving it at night, when it becomes a turtle hotel. Turtles from the surrounding area use the wreck as a place to sleep, and it is not uncommon to see 10 or more turtles on a dive. In addition to the turtles, there are lots of other critters that make an appearance. I’ve seen sharks, eagle rays, mating turtles, big stingrays, and every crustacean you can imagine on that wreck at night. You can even dive historical wreck sites on Statia. At sites such as Double Wreck and Triple Wreck, you can dive among historical artifacts from the colonial period. The wooden ships these artifacts were once part of have disintegrated due to teredo worms, but all the non-organic parts of the vessels are still there. I have conducted many years of archaeological research on these sites, and have learned a lot about them over the years. At these sites, you always see lots of southern stingrays in the sand, and there’s a good chance for turtles as well. These sites are also great for smaller critters such as sea horses and frogfish. Statia is great for non-divers as well. As I mentioned above, there is great hiking and many historical sites on the island. The black sand beaches are small but uncrowded. Snorkeling is fun, but a bit limited. Very special is to snorkel among the submerged ruins of the 18th-century port district. Throughout the day, there’s lots of life here, and at dusk, you can spot lemon sharks in this area. Statia is a very diverse diving destination. While the island (and the Eastern Caribbean in general) doesn’t have the vibrant reefs of the Coral Triangle, the big animals of the Eastern Tropical Pacific, or the fascinating shipwrecks of Truk or the Solomon Islands, it is one of the most varied diving destinations in the Eastern Caribbean. As a photographer or videographer, you have plenty of great opportunities to get interesting shots in a location that is not overcrowded like some sites on Cozumel or Bonaire. Having said all of that, we also have to be realistic and look at the not so bright side. The island is changing rapidly. There is now a big development on the eastern side of the island, where a large resort has recently opened. Stony Coral Tissue Loss Disease is wreaking havoc throughout the Caribbean, and Statia’s reefs are not immune to it. Moreover, the island experiences the effects of hurricanes, which can cause difficulties getting to the island and can change the marine environment dramatically. Eastern Caribbean reefs are not pristine environments anymore, far from it. There’s a general lack of top predators on the reefs, acropora corals have been decimated, and many species are heavily overfished. But within this context, there is still fun diving on Statia. Here you can get away from the crowds and experience the Caribbean like it was on other islands 50 years ago. Therefore I recommend it for anyone wanting to take a trip to the Eastern Caribbean and go off the beaten path. Bring a fisheye lens to capture expansive reef scenes A frogfish at Double Wreck An 18th-century anchor at the Lost Anchors site Snorkeling among the submerged 18th-century warehouse ruins just offshore The island has a lot to offer topside as well, such as hiking the 2,000-foot-high Quill volcano. You can even hike down into the crater.
  12. My first leafy sea dragon I found after moving to South Australia, I was very excited to finally see one. They're very shy and tend to turn away from you when you approach, so I got very lucky with this portrait. R5, 15-35mm, 2 x Z330s
  13. Moving this one over from the previous forum. I have for sale a complete Canon R5 Nauticam set in excellent condition. Bought new from Blue Water Photo at the end of 2020. I've taken it on around 75 dives, give or take a few. It's always been well rinsed after every dive, and has never been flooded. Here's a list of the items for sale: - NA-R5 housing - Canon R5 body + battery + charger - Canon RF 15-35mm f2.8 lens - Zoom gear for the 15-35mm lens - Canon EF 8-15mm f4 fisheye lens - EF to RF adapter - ZEN 230mm glass dome port - Nauticam N120 extension ring 30 (for 8-15mm lens) - Nauticam N120 extension ring 70 (for 15-35mm lens) - Nauticam flash trigger for Canon - Nauticam M16 vacuum valve + pump - Nauticam lanyard - 256GB Sony Tough CfExpress card and 64GB Sandisk Extreme SD card - Spare o-rings and lubricant The housing has a few small scratches on the bottom as you can see in the photos. Apart from that, it is like new. The ZEN dome has some hard water stains on the metal and a few tiny scratches on the bottom of the metal, but the glass is flawless. Both lenses are in mint condition with flawless glass as well. The R5 is fully functioning and has never let me down. It has the latest firmware installed. I have not done much topside shooting with it, so it is in great condition. I love this camera and the images it produces, but unfortunately I travel a lot on small planes so I need to downsize. It is a great setup for both photo (45mp) and video (8k30 and 4k120), shooting anything from reef scenes, wrecks and big animals to shy sharks and fish portraits. The retail price of this set with taxes is over US$ 18,000. I am willing to part with it for US$ 9,500 net to me. I will include shipping. The items are located in Adelaide, South Australia. Pick up is possible if you live nearby. I prefer to sell this as a complete set, but will consider breaking it up. I already have an interested party for the dome and flash trigger. I'm happy to provide additional photos and answer any questions you may have.
  14. Thanks everyone! @bghazzal Good questions! The shipwreck site and most of its associated artifacts was exposed during hurricanes Irma and Maria in 2017. I had dived in this area many times before, but after the hurricane, about 5 feet of sea floor was just removed and the site was exposed, that's why we are able to conduct research without excavating. The plate is of a type called delftware. It was made it the Netherlands, but like you said, it looks just like Chinese porcelain. This was a cheap Dutch alternative to the more expensive and higher-quality Chinese ceramics. @Davide DB You'd have a lot of fun with rebreather/scooter there. Along the volcano in the south, we have some very steep and deep walls, which have not been explored past 60 meters. Yes, all archaeological remains are protected by law on the Dutch BES islands (Bonaire, St. Eustatius, Saba). They have kind of a double layer of legal protection, both through local ordinances from the national parks, but also through Dutch national law. However, legislation is one thing, enforcement is another. There have been instances in recent times where people have taken things they shouldn't have, but it's definitely not as bad as it used to be. Back when diving tourism was emerging, St. Eustatius was actually advertised as an underwater treasure hunting destination. If you ever come across the Skin Diver magazine issue of April 1986, it has an article dedicated to it. Back then, divers brought up hundreds of artifacts to take home. That was a very different time... We always work with local heritage and national parks organizations, and of course only under government permits. @TimG I'd love to! I'll put some text together next week with some nice photos, and get back to you on that.
  15. I thought I'd share some pics of some underwater archaeology projects I've led throughout the Caribbean over the years. I used to just focus on wildlife/reefscapes, but the past few years, I've used UW photography mainly as a tool to capture and share research and new discoveries. This gallery gives a pretty good idea of some of the methods we've used and things we've found. When photographing our research, I always like to keep things simple. It can get very crowded on an underwater archaeological site, with divers, bubbles, fins, sediment everywhere. I like to focus on one specific element/person/discovery in my photos, which I think helps to tell the story. On St. Eustatius, I've worked on a specific 18th-century shipwreck site for 3 years, during which time we documented the site in detail and recovered many artifacts that were in danger of getting destroyed during future hurricanes. In addition, the historic roadstead has largely been mapped, in the process finding over 50 historic anchors, numerous cannons, and several other shipwreck sites. On Bonaire, the main focus has been the study of the anchorages at the salt pans in the south. There was a significant terrestrial component to it, as most of you who have been to Bonaire will know, such as the cabins of the enslaved salt workers, obelisks and bollards, and several other ruins. Underwater, we've focused on three different methodologies: surveying the shallow areas by snorkeling, documenting anything on the dropoff on SCUBA, and mapping the deeper areas down to 400 ft with an ROV. Recent research on Bonaire has focused on documenting a large shipwreck site on the east coast in the Spelonk area. In Turks & Caicos, several shipwreck sites have thus far been investigated. We have just started the investigation of the historic roadstead of Salt Cay, and are getting a better insight into historic shipping activities around the island. As I'm sure you can imagine, the actual underwater research is just a small component of a project. Artifact conservation, data processing, archival research, report writing, and public outreach all take up a considerable amount of time. But since this is an underwater photography forum, the pictures will focus on the underwater part of the research. All images were taken by myself. Here we go: We often try to gather information without even disturbing the sea floor. Here, we are using a metal detector to investigate whether there are any metal components from a shipwreck present in the sea floor. By mapping these signatures, we can get a very good idea of the size and extent of a site, without ever even excavating. We found many glass bottles on our shipwreck site on St. Eustatius. They would have held wine or sometimes a different liquid. They are very fragile and were therefore recovered, underwent conservation treatment, and are now on display. One of our students after just finding this beautiful 18th-century ceramic plate. The image on the plate represents a saint, but we are still not sure who exactly is depicted. The distribution of lost anchors around St. Eustatius has helped us to determine the extent of the historic anchorage. Some shallow sites around the island contain lots of cannons. They are a prime indicator of a shipwreck site. This Spanish olive jar is the largest artifact we have recovered to date. It took several months of conservation treatment before it was in a stable condition. It is currently on display. An important part of the study of the anchorages on Bonaire has been to map archaeological remains along the dropoff. This anchor was found to the north of the Red Slave dive site. null We've been studying this wooden wreck in the Turks & Caicos Islands quite intensively. It is quite rare to find this much wood on a shipwreck site in the Caribbean; normally wood is destroyed within years by teredo worms. The fact that this wreck site is still relatively intact is probably because it has been exposed during a recent storm. We think it might be a salt ship from the 1850s, but need to conduct more research next year to confirm this. One of the most spectacular historic shipwreck sites in the Caribbean is that of the HMS Endymion, a British fifth rate man-of-war that wrecked on an uncharted reef in the Turks Islands in 1790. We've been doing lots of archival research and are piecing together important information regarding the events that surround the wrecking.
  16. Thanks, coming right up Davide!
  17. Thanks! I've been doing research mostly on St. Eustatius, Bonaire, and Turks & Caicos over the years. There's so much to explore in Caribbean waters from an archaeological point of view, it never ends! Australian waters are definitely a bit cooler! I thought the Caribbean in winter was cold, but this is just on another level, haha...
