Low volume masks, purge snorkels

Masks & snorkels

Clear field of view, low volume for equalising on the drop.

The engineering case

The two masks, honestly compared.

Rob Allen makes two freedive masks and they are built for different faces. I size every mask order by hand because getting this wrong is the fastest way to ruin a dive.

Snapper EVO — anti-allergic skirt, integrated frame

The Snapper EVO uses an anti-allergic latex skirt fused to an integrated frame — no separate clip-on frame that can rub the cheekbones. Dual tempered lens, push-button buckles designed to adjust one-handed even with gloves on. It is the all-rounder mask for most faces.

Cracker — ultra-low-volume for small faces + deep divers

The Cracker is positioned explicitly for small faces and freedivers going past 25 m — lower internal volume than the Snapper means you use less lung air to equalise the mask on the way down. The tradeoff is real: Rob Allen say it outright, the Cracker is tight for larger faces. Do not order a Cracker for a broad-cheekbone face.

No published volume numbers — fit is the spec

Rob Allen does not publish exact internal volume numbers for either mask, so you cannot spec-compare them on paper. Pick by face shape (broad = Snapper, narrow/deep diver = Cracker), not by number. Message me your face width measurement if you want me to pick.

If you are new to freediving and not sure whether depth will matter, get the Snapper — it is the safer default for most Thai-market faces.

Before you buy

Masks & snorkels — common questions

Why low-volume masks for spearfishing? +

Less air to equalise on the drop, smaller profile so the mask sits closer to your face and does not get pushed by currents. You will see a real difference past 8-10m.

Do I need a purge snorkel? +

Optional. A straight snorkel is simpler and has less drag. Purge helps if you dive in chop and swallow water often. Personal preference.
