S.U.P.E.R. Part 2: Mares EOS 12RZ Dive Torch



In our ongoing series S.U.P.E.R. (Scubaverse’s Underwater Photography Equipment Reviews), Nick and Caroline Robertson Brown from Frogfish Photography will be reviewing new underwater photography equipment, general diving equipment, and some older favourites too. 

For the second instalment of S.U.P.E.R., Nick and Caroline will be looking at the EOS 12RZ Dive Torch from Mares.

Mares 1

Mares 4The Mares EOS 12RZ dive torch was designed as a dive torch, but we have been using it for a few months now as both a modelling light and as a photo/video light mounted on our camera systems. It is extremely versatile due to a host of features – and even better, it comes in at the great retail price of £178.

The EOS 12RZ features three high-power LEDs generating 1200 lumens of light intensity. The highlight for us is the innovative zoom system that makes it possible to modify the beam of light as needed. You can zoom the focus to alternate from a very broad beam to a tighter, more intense light beam. This is great for underwater photography and videography, as you can alter the torch beam to suit whether you want a more snoot like shot, or whether you want to illuminate a wider scene or even to use the light as a spotting light.

Mares 3It also looks great when you hand over this torch to your underwater model. Again you can use the ability to create a tight, bright beam, or a wider light flood, to alter the look of your images.

The magnetic switch offers a full power, low power and strobe function, and thanks to a USB cable and the LED charge indicator, the torch can be charged using a plug or computer. The torch has never run out of power on us, even on a 4-dive day (although we rarely keep a torch burning for a whole dive). Mares say that at full power it will burn for 2 hours and, at reduced power, for more like 5 hours.

Mares 2In order to mount this dive torch on our camera system, we had to buy an additional torch mount, as this does not come with the Mares package. We went for an Ultralight Torch Holder which cost £32.99, making our package of a versatile dive light and mounting system come in at the amazingly good value of £210.99. The 12RZ is the top of the range, but if you are on a tighter budget, there are less powerful options available, still with the zoom capacity, at even lower prices.

We have a number of different options for a constant beam light in our equipment room, although one fewer now that Caroline managed to drop our FIT light into an abyss on a recent trip! This Mares torch is an excellent addition.

Peli proud to support COVID-19 vaccine distribution



We know Peli from its popular camera cases, but from discovery to distribution, Peli’s temperature-controlled packaging is now delivering COVID-19 vaccines all over Europe and the Middle East

With the pandemic recovery just underway, COVID-19 vaccines and therapies are rapidly becoming available for use and they must be safely distributed worldwide, within their required temperature range. Peli’s BioThermal™ division is providing temperature-controlled packaging to meet this critical moment, protecting these crucial payloads.

Peli’s innovative cold chain packaging has been trusted for nearly 20 years by pharmaceutical manufacturers to safely ship their life-saving products around the world. To meet the current challenge, they have adapted their existing products to provide deep frozen temperatures when required for the newly developed life sciences materials. Current and new offerings will ensure the cold chain is maintained throughout the vaccine or therapy’s journey, maximising efficacy and patient health.

“We know that pharmaceutical companies are in all phases of the development process for vaccines and therapeutics and working tirelessly to bring safe and effective drug products to market quickly,” said Greg Wheatley, Vice President of Worldwide New Product Development and Engineering at Peli BioThermal. “Our engineering team matched this urgency to ensure they have the correct temperature-controlled packaging to meet them where they’re at in drug development for the pandemic recovery, from discovery to distribution.”

Peli BioThermal’s deep frozen products use phase change material (PCM) and dry ice systems to provide frozen payload protection with durations from 72 hours to 144+ hours. Payload capacities range from 1 to 96 litres for parcel shippers and 140 to 1,686 litres for pallet shippers.

New deep-frozen solutions are ideal for short-term vaccine storage, redirect courier transport of vaccines from freezer farm hubs to immunisation locations and daily vaccine replenishment to remote and rural areas.

Peli BioThermal temperature-controlled packaging is currently being used to distribute COVID-19 vaccines and therapeutics, either directly or through global transportation providers, in Denmark, France, Italy, Germany, Spain, Sweden, and the UK as well as in Kuwait and Saudi Arabia in the Middle East, with more countries set to join the list as the pandemic recovery process rolls out.
