The Ammonite LED Speleo MK2 torch strikes the perfect balance between power and operating time, making it an ideal light source for a wide range of underwater activities. Its focused 6-degree beam, complemented by a gentle corona, provides excellent communication properties, giving divers heightened awareness of their surroundings. Whether exploring a sunken wreck or navigating a cave system, the Ammonite LED Speleo MK2 torch is the perfect tool for the job, delivering reliable and efficient performance every time.

The Ammonite LED Speleo MK2 torch is a top-of-the-line umbilical diving light that’s not only powerful and versatile but also part of the Ammonite modular system. This means that all Ammonite System umbilical headlights, cables, batteries, and heating batteries are fully interchangeable. This modularity allows you to configure your set according to your specific requirements, for example, easily change from backmount to side mount configuration, exchange the battery or Goodman handle type. It also makes it easy to upgrade or replace parts as needed in the future.

The Ammonite LED Speleo MK2 torch provides up to 3000 lumens of light. And with three different light modes to choose from, you can easily adjust the brightness to suit your needs. In BACK-UP mode, you’ll get approximately 20% of the maximum light output, while OPERATIONAL mode offers approximately 40%. And for maximum brightness, BOOST mode is the way to go. Adjusting the light output also helps to minimize backscatter in murky water conditions. In OPERATIONAL mode, you can expect up to 10 hours of burn time, while in BACK-UP mode, it can last for over 25 hours when paired with the smallest Ammonite System battery, ACCU TYPE 9.

The Ammonite LED Speleo MK2 torch is equipped with an easy-to-operate switch adjustor that allows for better optimization of the light amount. It features three operating modes that cater to a diverse range of needs.

The Ammonite LED Speleo MK2 torch’s compact and lightweight design makes it incredibly easy and convenient to operate, allowing divers to focus on their exploration without being encumbered by heavy or cumbersome light heads. It is only 116 mm in length and 53 mm in diameter and weighs only 262 g (100 g in water). The Ammonite LED Speleo MK2 torch is also an ideal choice for use with Ammonite System Goodman handles, as it allows for greater maneuverability and comfort during extended dives.

The Ammonite LED Speleo MK2 torch’s advanced microchip system enhances safety during dives by providing status signaling and low battery alerts. When the battery level becomes low, the microchip system signals the user with a strobe flash, and switches to “take me home mode” providing over 1hr of additional operating time and thus a reliable way to ensure that divers can return to the surface safely.

The Ammonite LED Speleo MK2 torch’s “take me home” mode is a backup mode that the light switches to when the battery is drained, providing divers with a reliable way to return to the surface. In “take me home” mode, the light will continue to operate for at least 1 hour or more, depending on the light and the used accumulator. This ensures that divers have enough time to finish the dive when the battery runs out. It is important to note that the light will remain working only in “take me home” mode until the battery is recharged again. This means that it is essential to recharge the battery after every dive to ensure that the light is ready for the next use. By alerting divers to low battery levels and providing a backup mode in case of battery depletion, the Ammonite LED Speleo MK2 torch enhances the overall safety of diving expeditions. Divers can explore with confidence, knowing that they will be alerted if the battery level becomes critical, and that they have a reliable mode to ensure a safe return to the surface.
