Visual Indication Systems

Natural Evolution

When we introduced the Delkim Plus range of electronic bite alarms in 2003 we included the unique NiteLite output socket to power the original NiteLite illuminated hanger.  This led to the natural evolution of the NiteLite Pro, DuoCarb, the ES Indication Set and SlimLite.  The revolutionary detachable DuoCarb hanger support incorporating lightweight carbon fibre tubes enabled the NiteLite Pro hangers to be used in windy conditions with minimal weight increase which was yet another first for Delkim.

Our range of options suit all styles of Carp & Specialist Angling with each variation having it’s own unique features.  All of our Visual Bite Indicators are dedicated products designed to compliment and get the very best visual and audible indication from the Delkim Plus Range of electronic bite alarms.  From the feather light SlimLite/SlimCarb to the NiteLite Pro/DuoCarb there is a combination to suit everyone.
