The DOOLIN 4K Spot is a very intense 8 degree spot asked for by cave divers and divers diving in very poor visibility. Named after a famous cave diving site in Ireland, the DOOLIN is an excellent addition to our range of modular dive lights. The DOOLIN has all the usual Anchor Dive Lights features including a modular head, runtime as handheld of 90 minutes on full power, and different intensity settings. The modular head works with existing handhelds, umbilical cables and canisters. Divers can choose from intensity setting of 100%, 50%, 25% and 10%. Where the 50% intensity will give an astonishing runtime of 6 hours, requested by cave divers. DOOLIN has been tested over 150m, and has a CE approval to 100m. It also works with all existing canisters, Goodman handle ERRIGAL and ball adapters.
