Teric Color Scuba Diving Computer Review: Runs the Bühlmann ZHL-16c Algorithm for Decompression Diving

Teric Color Overview

Shearwater Research Teric Color computes decompression profiles using a Bhlmann ZHL-16c algorithm for divers who require a wrist-watch form factor.

The Bhlmann ZHL-16c algorithm provides a consistent method for calculating decompression limits during deep dives. This specific mathematical model helps manage the time a diver can spend at depth based on their ascent profile.

The Shearwater Research Teric Color implements this algorithm in a compact design that includes switchable audible and vibration alerts. These alerts notify you of depth or time limits through sound or physical pulses on the wrist.

The Short Answer on the Teric Color

Best for: you need a wrist-watch form factor dive computer that supports Nitrox Trimix decompression and provides switchable audible and vibration alerts.

The Teric Color is a capable option at the $580 mark.

• Pro: The Bhlmann ZHL-16c algorithm supports complex decompression profiles for deeper dives.
• Pro: It features a 4.8 rating from 264 buyers, indicating a consistent user experience.
• Pro: You can use optional wireless tank pressure transmitters to monitor gas levels.
• Con: The 40 gram weight is light, but the nylon material may not suit those seeking a hard-shell casing.

Don’t buy this if: you require a dive computer with a hard-shell housing, as this model uses a nylon material construction.

Price assessment: The $580 price point is a premium investment for a specialized Nitrox Trimix dive computer.

Before You Buy: Dive Computer Checklist

The first thing to check is the Bhlmann ZHL-16c algorithm, which is the mathematical model the computer uses to calculate your remaining dive time and decompression limits.

• ☐ Confirm the wrist-watch form factor fits your preference — a 5 x 4.5 x 3.25 inch footprint may be larger than a standard watch if you require a smaller profile.
• ☐ Verify the weight of 40 Grams fits your gear setup — a heavier unit may shift on the wrist during long dives.
• ☐ Check for wireless tank pressure transmitter compatibility — the Teric Color supports optional wireless transmitters to display tank pressure on your wrist.
• ☐ Budget for the $580 price point — this cost is the entry point for the specific features and algorithms included in this model.
• ☐ Confirm the material is Nylon — a nylon strap construction differs from silicone or rubber options in how it sits against the skin.

You should not buy this product if you require a traditional dive computer that does not support the Bhlmann ZHL-16c algorithm.

You can connect existing wireless tank pressure transmitters to the Teric Color because it supports optional wireless tank pressure transmitters. If your current transmitters use a different wireless protocol than the one specified by the manufacturer, the data for that specific connection standard is not stated.

What These Specifications Let You Do

How the Bühlmann ZHL-16c algorithm enables technical dive planning

The Shearwater Research Teric Color supports the Bühlmann ZHL-16c algorithm, which is the standard decompression model used to calculate how much nitrogen or oxygen your body absorbs during a dive. Because this model is a standard for technical diving, it allows you to plan and execute dives using various gas mixes, including Trimix, which is essential for deep dives to manage narcosis and oxygen toxicity.

Teric Color provides this support to ensure you can manage complex decompression profiles while staying within safe gas limits. By using this specific algorithm, you can rely on the device to provide deco requirements for technical profiles that require multiple gas switches, moving you beyond the limitations of basic recreational dive computers.

Customizing decompression stops with configurable Gradient Factors

Configurable Gradient Factors (GF) are settings that allow you to adjust the conservatism of your decompression stops, specifically by defining the depth and time limits for your ascent. You can customize these values to suit your specific training level or personal safety preferences, allowing for a more tailored decompression plan than a fixed, non-adjustable model provides.

Teric Color allows you to input your own GF values to determine how the computer handles your ascent profile. This level of customization means you can choose a more conservative approach for deep technical dives or a more aggressive profile if your training and gas plan permit, providing a direct link between your personal dive plan and the device’s output.

Using this underwater computer for freediving and gauge modes

Freediving mode allows you to use the device for breath-hold diving by providing specialized data such as depth and time without decompression calculations. In this mode, the device functions as a dedicated freediving computer, which removes the complexity of gas management and focuses on your depth and duration limits.

Teric Color also supports Gauge mode, which treats the device as a simple underwater computer that displays depth and time without any decompression modeling. You can switch to this mode for basic dives or when you do not require the data provided by a decompression algorithm, allowing the device to serve as a simple depth gauge.

The Teric Color Against Similar Scuba Diving Computers

The Teric Color offers the highest buyer rating of the options we evaluated, with a 4.8 average across 264 ratings. This rating represents the feedback of 264 buyers who have purchased the device.

Setting Up This Scuba Diving Computer, and What Support Covers

Getting Your Teric Color Ready

You need a compatible charging cable to provide power to the device before you can begin your first dive.

1. Unpack the Teric Color and inspect the nylon housing for any transit damage.
2. Connect the charging cable to the unit to replenish the internal power source.
3. Select your preferred orientation in the menu to set up the Bhlmann ZHL-16c algorithm, which calculates your no-decompression limits.
4. Verify that the switchable audible and vibration alerts are active for your safety needs.

Warranty and Support: What to Check

Warranty coverage and return policies vary by the specific seller and your country of purchase.

• Confirm the screen functions correctly in the Gauge mode to ensure the display is not defective.
• Check that the vibration alerts trigger at the expected intervals, as these are not user-serviceable internal components.
• Verify the device weight remains at 40 grams to ensure no internal components are loose or missing.

Perform a full menu cycle and check the display for any dead pixels the day the unit arrives while your return window is still open.

Teric Color Buying Questions Answered

Scuba diving computer suitability

The Teric Color is a Nitrox Trimix decompression dive computer, meaning it supports mixed gas breathing and decompression stops to manage nitrogen levels. This specific model uses the Bhlmann ZHL-16c algorithm, which is a standard formula for calculating how much nitrogen your body absorbs during a dive. Because it supports Freediving mode and Gauge mode, you can use this device for different types of underwater activity beyond standard scuba diving.

Teric Color dimensions and weight

The Teric Color weighs 40 Grams and measures 5 x 4.5 x 3.25 inches. At 40 Grams, the weight of the device is comparable to a standard wristwatch, making it easy to wear for long periods. The 3.25-inch height ensures the unit sits comfortably on the wrist without protruding excessively.

How the nylon strap ensures long term durability and maintenance

The strap on the Teric Color is made of Nylon. Nylon is a synthetic fiber that resists degradation from salt water and handles frequent rinsing well, ensuring the strap remains intact after repeated ocean use. If you are concerned about material longevity, this nylon construction provides a durable interface for the 40 Gram device.
