Things to Consider When Buying the Best Entry-Level Dive Computer

What makes for the best dive computers for beginners? What should beginner divers need to look for in terms of a reliable dive monitor? Here are things to consider as you choose your first dive computer:


Choose the Best Style According to your Preference

There is a wide range of diving computers of various styles and functions. Wrist computers are the best choice for beginners as they have more features and functions than dive watches. This is especially helpful in reading information underwater or limiting visibility by low light conditions or cold water temperatures.


Expensive or Affordable? It Depends on Quality

Most dive computers have always been an expensive purchase for divers. However, plenty of cheap models will fit your budget and won’t leave you broke if something goes wrong with the device down in deep waters.

After researching which type of device best suits your driving needs, make sure you understand the kind of warranty each device covers.


Dive Computers Should Withstand Underwater Conditions

Underwater conditions can be challenging, if not harsh. Such devices with lower water resistance levels cannot withstand deeper dives. At the same time, strap materials are also significant factors in their durability. Thus, look for devices that are strong enough and suitable for your diving preferences.

Brightness & Screen Size

Ensure that the Texts are Readable

The essential function of a diving computer is to monitor several metrics necessary for your immersion in deep waters. In this case, look for devices with larger screen sizes, readable texts, and high brightness levels. Now, this will come in handy in various conditions, especially in low and ambient light.


Easy-Navigation is the Key

Many models on the market have easy-to-navigate menus for planning your dives with ease and logging data to monitor it after a trip underwater. More so, you won’t need any bells or whistles because these entry-level devices will serve you just fine – both now and when you decide to upgrade later down the line!

Yes. Diving computers are a must for people who are about to start their diving journey. While some prefer the use of dive tables as their guide, diving can be risky for beginners.
