Introduction – A Reliable LCD Dive Computer with Modern Features

While the dive computer market is dominated by full-colour screens, there remains a strong case for traditional LCD displays. The Seac Tablet dive computer shows exactly why — it combines clarity, functionality, and value in one robust package.

Designed for divers who value legibility and intuitive operation, the Tablet’s easy-to-read LCD display features adjustable contrast and backlighting. The flexible graphic layout and simple icon interface make it effortless to monitor dive data, even in low visibility or night dives.

Design and Usability

Despite its modest screen size, the Seac Tablet’s digits are large, crisp, and well laid out. This makes it ideal for divers in darker or murkier conditions, where readability is critical. The two front-mounted push buttons provide straightforward access to all menus, and operation remains simple even with 5mm neoprene gloves.

The Seac Tablet dive computer strikes a strong balance between ease of use and professional capability, positioning itself as one of the best budget air-integrated dive computers available in its class.

Dive Modes and Algorithm

The Seac Tablet is feature-rich, offering three operational modes: Scuba, Gauge, and Freedive. It uses the proven Bühlmann ZHL-16C algorithm, trusted by divers worldwide for its reliability and accuracy.

• Scuba Mode manages dives with up to three Nitrox mixes (O₂ concentrations up to 99%) and six levels of custom conservatism.
• Gauge Mode offers a dedicated depth gauge and stopwatch for independent profile management.
• Freedive Mode tracks current depth, maximum depth, and surface intervals — and includes an “Off” mode for static apnea training.

Air Integration and Connectivity

One of the standout features is the Seac Tablet’s air integration capability. It can be paired with up to three wireless transmitters (SRP £255 each), giving divers real-time monitoring of tank pressure and remaining gas time. This feature optimises bottom time and decompression planning based on residual gas — an impressive inclusion at this price point.

Dive data is automatically logged, with the built-in logbook capable of storing 65 hours of diving in Scuba or Gauge mode and 24 hours in Freedive mode. Data can be transferred easily via Bluetooth or USB cable (sold separately) to the Seac smartphone app or PC software.

Comfort and Battery Life

The Seac Tablet comes with a fitted double silicone strap available in two colourways and includes a bungee mounting option for technical divers. The strap is long enough to fit around a drysuit arm, with an extension strap available for larger setups.

Power comes from a long-life user-replaceable battery, rated for approximately 600 dives over two years, which can be changed easily by removing a few small screws.
