Spearfishing masks and snorkels are essential gear for spearfishers, designed to enhance visibility underwater and facilitate breathing while diving. 
Here are some key considerations:

Spearfishing masks typically have a low internal volume, which reduces the amount of air needed to equalise the mask as you descend. Masks should have tempered glass lenses to ensure safety and durability underwater and remember a good spearfishing mask should fit comfortably on your face without leaking. 

Opt for a mask that offers a wide field of view, allowing you to see more of your surroundings underwater. Some masks come in camouflage patterns to help blend into the underwater environment, 

Spearfishing snorkels are typically simple in design with a J-shaped or semi-dry top to minimise water entry while diving.

Look for snorkels with a comfortable silicone mouthpiece that fits well and allows for easy breathing. The snorkel tube should be flexible and lightweight, making it easy to position out of the way when not in use. As for comfort, ensure compatibility between your snorkel and mask to prevent interference or discomfort while diving.

When choosing spearfishing masks and snorkels, personal comfort and fit are crucial. It is very important to consider the conditions in which you'll be diving, such as water temperature and visibility- Select the most suitable gear for your needs.
