About Sub Gravity H3 Dive Computer

The Sub Gravity H3 smart watch, powered by Sea Bear Diving Technology, is the first smart watch" dive computer ever. Compact size, fully capable, with modern features and technology! The Hþ is the first watch size dive computer with a color OLED screen. It is manufactured from the toughest materials 316L stainless steel and a scratch resistant sapphire window. The H3 is the first watch size dive computer with a color OLED screen. It is manufactured from the toughest materials 316L stainless steel and a scratch resistant sapphire window. The H3 is not only a sophisticate dive computer. The precise compass and the altimeter are ideal for outdoor activities. Last but not least, its stylish design makes it the ideal companion for daily life. Core component of the H3 is an ultra low power 32-bit microcontroller. A precise 24-bit ambient pressure sensor is used to measure depth and altitude. Data are store on a 32-MBit Flash Memory.

ZH-L16 Algorithm:
The H3 uses the Buehlmann ZH-L16 algorithm together with Gradient Factors. The algorithm is based on 16 compartments for nitrogen and 16 compartments for helium. With up to 8 pre-programmable gases it is possible to use the H3 for the most sophisticated technical dives. A 16 compartment bar graph visualizes inert gas loadings during the dive. The H3 comes as nitrox dive computer and can be upgraded for multi-gas, trimix and CCR diving.

Color OLED Screen:
The crisp 1.7" (4.3cm) color OLED screen is easily readable under all conditions. Especially in deep, night and cave dives the bright and high contrast screen is much easier to read than conventional LCD screens.

Multi-Screen Display:
Select which data to display: You can switch the H3 between several screens.

A 3-axis tilt compensated digital compass will facilitate navigation in diving as well as during other outdoor activities.

The integrated pressure sensor allows using the H3 as altimeter from 0-10000m altitude.

USB Port:
Connect the H3 to a USB port to charge the inbuilt Li-Ion 4.2V, 400mAh battery and to download dive data from the 32-MBit Flash Memory or to update the Firmware. Firmware updates can be downloaded from the SEABEAR website free of charge.

Smart Watch:
The SEABEAR H3 is the first dive computer equipped with a Near Field Communication Interface (NFC) for seamless integration into mobile environments. Dive data can easily be downloaded to NFC enable smart phones without the need for pairing the devices.

Social Networks Ready:
An app is available for Android phones to download and visualize dives. Share your dive profiles and data with a single touch on social networks like Facebook or Twitter.

The SEABEAR H3 can be used as dive computer for Air, Nitrox, Trimix, closed circuit re-breather and apnea diving. Up to 8 gases can be programmed for open circuit diving. If the SEABEAR T1 is unlocked for CCR diving, then also 8 diluent gases and 2 pO2 set-points can be programmed. A USB port is located on the side to recharge the inbuilt Li-Ion 4.2V, 900mAh battery and to download dive log files. The SEABEAR H3 is also an active NFC tag, which means that dive data can instantly be transferred to NFC enabled mobile devices for detailed visualization and for sharing on social networks.

The H3 comes with a durable wrist mount strap. The computer has a depth rating of 426.5' (130 meters) and comes with an owner's manual.
