This is one serious bit of kit. It’s the daddy of torches, the one that you dream about while you’re sleep diving.

The light beam is focusable so use the wide-angle beam to illuminate your cave or wreck, and then switch it to a narrow beam to signal to your buddy.

The Honest Truth



I thought the Helios system was the torch to end it all… When Ammonite brought out the LED Nautilus, I couldn’t believe they went one step further. It’s insane – like having the sun strapped to your wrist!

All kits come in a hard case containing:

  • Ammonite Systems LED Nautilus head
  • Your chosen Accu or Accu Thermo battery
  • Your chosen umbilical cable
  • Spare o-rings and allen keys
  • Battery charger with power cable

What Battery Do I Need?

Use Accu Batteries for powering your torch.

Use Accu Thermo Batteries for powering your torch and your heated undergarments. The Accu Thermo also tells you how much charge it’s got left with a handy indicator light.

Manufacturer's Bumph


As an experienced diver, you know perfectly how it is difficult to find a dive light that’s bright, durable, lightweight and works reliably in almost every condition.

LED NAUTILUS is all that, but above these, it offers the adjustable beam angle (focusable) that switches between an intense focus to a wide perfectly round beam.



This innovative dive light utilizes the latest COB Cree CXB chip and Fresnel lens that allows providing impressive 4000 lumens of light and smoothly adjust the light beam to as low as 9 degrees and as high as 45 degrees.

LED NAUTILUS can be combined with different cables (E/O cord, Standard or Sidemount cable ) and different batteries (ACCU TYPE 24, ACCU TYPE 14 and ACCU TYPE 10) or heating batteries (ACCU THERMO 24, ACCU THERMO 14, ACCU THERMO 24 Special).



LED NAUTILUS features three light levels BOOST, OPERATIONAL and BACK-UP to preserve battery and adjust brightness levels to eliminate backscatter in murky water.

The burn time of the light will depend on what level one has chosen.



All these features are packed in a relatively small housing, with only 140 mm length and 60 mm in diameter.

Yet while exceptionally durable, it respectively weighs 415 g and 150 g underwater.

Smooth and compact design is perfectly balanced making it easy to operate when in use with Goodman handle or without.



It is built from hard anodised marine aluminium making it resistant to corrosion, knocks and scratches.

Easy to operate switch knobs are made of lightweight but very tough and corrosion resistant polymer (Delrin®).

The 6 mm front glass is made of highly fatigue resistant tempered glass.

LED NAUTILUS is tested and can safely operate up to 150 m depth.



The electronic system controls the voltage level and signals low battery level with a strobe flash and automatically switches to back-up mode (light output at 20% light intensity) when the battery is drained.

LED NAUTILUS will only work to “take me home” mode until the battery is recharged again.
