Factors to consider when purchasing budget dive computers

Essential functions on budget dive computers

  • Backlight: A backlight is essential to ensure that you can easily read the data displayed on your dive computer, even in low-light conditions. The latest generation of OLED screens does not require a backlight.
  • Algorithm: The purpose of a dive computer is to keep you safe from decompression sickness (DCS). The dive computer decompression algorithm model makes those calculations. However, different models can affect your dive profile. The two main models use are:
    • Bühlmann ZHL-16C: Less inherently conservative. A tried and tested model. Favored by technical divers. Requires more diver caution.
    • RGBM: More conservative, limits dive time for repetitive and multi-day diving, penalizes unsafe diving behaviors. Compensates for less diver knowledge and skill.
  • Alarms: Alarms are crucial to ensure that you receive alerts when you need them, even if you’re not actively looking at your computer. Vibrating alarms cost more, but do not annoy other divers. Audible alarms are cheap and common.

Price considerations for budget diving computers

  • Battery: The type of battery is a cost-value factor in budget dive computers. There are three options:
    • Rechargeable: A lithium-ion battery that has to be frequently charged, but will not run out. These cost more but are very convenient.
    • User-replaceable: A standard watch battery with a long duration that the diver can change when needed. This is satisfactory and economical.
    • Dealer-replaceable: A battery that can only be replaced by sending the computer away to a manufacturer-approved dealer. These are not recommended.
  • Display: Look for a big (colorful) screen with a backlit display. OLED displays offer brilliant colors and clarity that are hard to beat and make reading the data underwater a lot easier.
  • Screen: If you have weak vision, then a larger and clearer display size becomes a primary decision factor. There are two main types of computer screens:
    • LED screens cost more, but are bright, clear, and colorful.
    • LCD color screens are more modern and costly but are easy to read.
    • LCD monotone screens look antiquated and do not present information as clearly. They are highly reliant on a backlight in dim or dark conditions.
  • Backlight: LCD screen dive computers require a backlight function. Some are always on, whereas others require a push-button. The backlight function is vital if you do night, wreck, or cavern diving.
  • Reliability and durability: The material quality of dive computers varies according to price. Look for the most rugged materials that you can afford:
    • Housing: Cheaper plastic materials are less robust than Delrin or steel.
    • Screen: Plastic screens scratch easily. Sapphire crystal screens cost more but are scratch and impact resistant.

Firmware options on budget diving computers


Modern divers often value being able to connect their computers to logging and planning applications on their smartphones or PC.

Some computers also offer cloud-based dive logs and the ability to share dive information directly to social media accounts.

In general, wireless Bluetooth is more costly than USB cable connectivity. However, wireless connectivity has many advantages.

It is very much a personal preference whether wireless connectivity is worth the extra money when considering budget diving computers.

Gas mixes

Every modern dive computer offers air and nitrox compatibility. However, some boast multiple gas mixes.

These are only a benefit for technical divers completing accelerated decompression dives. Do not spend more money on this feature unless you have firm plans for technical diving in the future.

Budget diving computers do not need the capability to switch between different gas mixes on a dive.

Decompression diving

There is a difference between computers that provide planned decompression for technical divers and those only providing emergency decompression for recreational divers.

If you have the ambition to progress into technical diving, be aware that many dive computers do not have suitable functions. This is not a major consideration for most entry-level divers considering budget diving computers.

How to determine the best budget dive computer model for your needs

Think about where you are now with your experience level and dive habits. What kind of dives are you doing now? Where do you want to be a few years from now?

Knowing your own preferences is the most surefire way to ensure you’ll be happy with the computer you buy. Try as many as you can while you’re at the rental stage, go to shops, and play around with demo models.

What to expect from a budget dive computer

Buying a dive computer can be overwhelming, especially for beginners. However, there are certain features that are suitable for new divers and won’t break the bank. Here’s what you can expect from a budget dive computer:

Basic Dive Computers for Beginners: Features ($200-$500)

Basic dive computers will provide you with the following features:

  • Single gas: air and nitrox
  • Bottom time, depth and NDL
  • Surface interval
  • Logged dives (0-100 dive capacity)
  • Emergency decompression stops
  • Ascent rate alarms
  • Average battery life
  • Mono or Dual button layout

Advanced Dive Computers for Beginners: Features ($500-$900)

Advanced dive computers include all the basic features from above, plus extra ones that will make your diving experience even better. This often includes:

  • Digital compass
  • Gauge mode
  • Freediving capabilities
  • 2-3 multiple gasses
  • Non-trimix technical diving
  • >40% O2 decompression gasses
  • Larger dive log database (100+ dives)
  • Good battery life
  • Dive planner
  • LED color display
  • Multi-button layout
  • USB chargeable

Premium Dive Computers for Beginners: Features ($900+)

Premium dive computers are the top-of-the-line offerings by manufacturers and are mostly aimed at dive professionals, frequent divers, and those who like to invest in quality wristwatches. These often enhance the features of lower-priced models while using better materials and design. Premium features may include:

  • Wireless air-integration
  • Smart-watch capabilities
  • GPS function
  • Extensive logbook functionality (500+ dives)
  • 5+ multiple gasses
  • Trimix technical diving capabilities
  • More durable materials (screen and housing)
  • Very good battery life
  • Extensive technical dive planning options
  • Regular wireless firmware updates and upgrades

Keep in mind that the more you spend, the better quality you get and the more features you will receive with a dive computer. However, it’s important to invest according to your needs, budget, and skill level. As a rule of thumb, for every 10-20 dives per year, spending an extra $150 on your dive computer is a good idea.
