Dive Computers
Dive computers are an essential piece of equipment for modern scuba divers, transforming complex dive planning into clear, real-time information at a glance.
Worn on the wrist or integrated into a console, these compact devices continuously monitor depth, time, and ascent rate, using advanced algorithms to calculate safe limits and decompression requirements throughout your dive.
Gone are the days of relying solely on dive tables—today’s dive computers provide instant feedback underwater, helping divers make informed decisions, extend bottom time safely, and reduce the risk of decompression illness.
From entry-level models designed for simplicity and ease of use, to advanced units with multigas capability, air integration, and digital compasses, there’s a dive computer to suit every level of experience.
Many modern dive computers also feature Bluetooth connectivity, digital logbooks, and customisable settings, allowing divers to analyse their dives, track progress, and tailor their experience to their individual needs.
Whether you're exploring shallow reefs, progressing through training, or planning technical dives, a reliable dive computer is your personal dive assistant—keeping you informed, safe, and in control every time you enter the water.
Dive computers allow the user to track important dive parameters such as depth and time. Some models include "Air Integration" which also tracks cylinder pressure and in turn can tell you your remaining air time, remaining air pressure and can calculate consumption rates as well as other useful information.
Please Note- All dive computor boxes are opened, quality checked, then resealed before despatch- To check the battery condition.
