Product Information
The TUSA IQ1204 DC Solar Link dive computer offers solar-powered reliability for scuba and diving enthusiasts. Its solar rechargeable design eliminates the need for battery replacements, while Bluetooth SMART technology transfers your dive log to a smartphone or tablet using the TUSA Diving LOG app. It supports 4 gas mixes (21-100%) and includes a Free-Dive Mode for freediving sessions.
Designed for safety and clarity underwater, the device uses the AA Buhlmann ZHL-16C decompression algorithm to guide ascents. It features audible and visual alarms for key dive data, a bright backlit display for easy reading in low light, and Altitude Smart Mode that automatically adjusts for altitude diving.
Beyond core dive data, the DC Solar Link provides versatile time tools and a user-friendly interface that suits a range of scuba and diving activities. Its full-auto LED backlight enhances visibility during night dives or low-light conditions.

Rechargeable by sunlight or indoor fluorescent light. The solar rechargeable feature eliminates the need for battery replacements.
Bluetooth® SMART technology enables smartphones or tablets with the Diving LOG app downloaded to receive dive log data from the IQ1204 DC Solar Dive Computer via Bluetooth®.
This advanced feature allows the diver to preset four individual gas mixtures (Mix 1, Mix 2, Mix 3, Mix 4) from 21-100% for easy switching during the dive.
The Altitude Smart Mode allows the computer to automatically adjust for altitude diving.
TUSA’s computers feature Audible and Visual Alarms for the most important dive data warnings. Ascent rate, maximum depth, no decompression limits, safety stop and several other key data can be set to alert the diver.
Several TUSA computer instruments feature a Backlit Display for night diving or low-light situations. The bright backlight is activated by a touch of a button and the duration can be set for up to 10 seconds in length enabling the diver to view critical dive data easily and quickly.
The Free Dive Mode calculates dive times and surface intervals for free diving.

Frequently Asked Questions
Why do I need my own dive computer?
A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.
Can two divers share one dive computer?
No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.
What does conservatism mean on a dive computer?
Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.
What kind of battery does a dive computer use?
Broadly there are two types: user-replaceable batteries, often a coin cell that you or a shop swap along with resealing an o-ring, and sealed rechargeable batteries that charge from a cable or dock. Neither is universally better, as replaceable cells are convenient on remote trips while rechargeables avoid ever opening the case. Follow the manual exactly for any battery change, because an improperly seated o-ring or case is the usual cause of a flooded computer.
Do I need to do anything special for altitude diving or flying after diving?
Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.
How do I care for a dive computer?
Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.
What is the difference between wrist, console, and air-integrated dive computers?
A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.
