Dive Slates Buying Guide

Dive slates are more than just simple writing equipment, as they help to create a diving experience that is safer and more detailed. Logically, the best dive slates need to be visible enough to compensate for decreasing visibility with depth underwater. Also, a dive slate should not be heavy.

It is an advantage if a dive slate is compatible with a large amount of pencils and erasers. This buying guide focuses on the crucial features of a dive slate and what you should look out for before you make a purchase.

Size and Weight

Any gear you will be diving with should be as convenient to carry around as possible. The same goes for a dive slate. As mentioned above, a dive slate should be lightweight and compact. It should just be big enough to contain a decent number of words and not too big that it creates too much drag in the water. It should also be very lightweight and weigh a few hundred grams at most. Carrying a slate as large as a board or even close to will be outright inconvenient.


It is important for you to be able to see whatever is being written on your slate while you are underwater. Most of the best dive slates are either white or brightly colored. This helps create enough contrast for good visibility. Additionally, there are a number of high-quality slates that are luminescent, meaning their underwater glow will allow you to see your writings easily.


Different companies produce their dive slates differently, and some slates have fewer pages than others. Some slates, in fact, are just one single leaf. If your dive scribblings are often extensive, and you just enjoy chatting underwater, it would be worthwhile to get one that has many pages.


This is another important factor to consider when buying a dive slate. Some slates are made to be attached to a diver’s wrist, and so, they have straps to hold them in place. Some other slates have hooks that can be attached to a BCD.
