I would like to buy a snorkel and mask, but dont no where to start, i would like a good one that wont leak,
The best mask for you is the one that’s most comfortable to wear. Everybody’s face is a different shape, so you should try on several masks to see which is most comfortable. A dive shop of any description will be your best bet for finding a wide selection.
To check whether the mask seals against your face, place it over your eyes and nose WITHOUT hooking the strap over your head, and inhale gently through your nose–if the mask sucks onto your face and prevents you from inhaling any further, it’s a good fit. You’ll need to clean the mask lens with white toothpaste before using it for the first time.
Snorkel selection is usually fairly straightforward. So long as it’s wide enough that you can breathe through it easily, it should be fine for you. For an average adult, the snorkel should be at least 20-25 mm (3/4 to 1") in diameter. Whatever model you buy, you’ll need to take deeper breaths than normal, to compensate for the extra ‘dead air’ space of the snorkel tube.
NB Most top-mounted Snorkel ‘splashguards/wave protectors’ etc. don’t work all that well, and if you skindive down under the water, the snorkel will flood regardless–so the extra bux for these attachments aren’t really worth it. If you have a lungful of air, a sharp ‘blast’ exhalation will clear any snorkel quite effectively.
Here’s a few specifics to look for:
Mask:
–Low volume (two-lens masks have a lower volume than single-lens masks)
–Tempered glass faceplate, not polycarbonate (glass stays clearer, and doesn’t scratch as easily)
–Silicone skirt, not rubber (silicone is softer, and less allergenic)
Snorkel:
–Silicone mouthpiece
–Drain valve (makes snorkel clearing easier)
–Simple, robust mask-strap attachment clip
