havent tried it in the ocean yet looks as if it will work
mask is heavier than i thought. tried mask in a pool with no restrictions works fine no problems. Have not yet tried it out in open water so i cant make any commits on it. Liked the quick disconect of the snorkel for easy packing in a suitcase or bag.
When using this product one can expect at least two dives before adding a new application,Product works very well after two dives but you may want to add another application if you have the mask sitting around for a while.Overall product works very well.
this product can erase a slate with only two s on a kleenex tissue and rubbed onto the slate.the writing on the slate comes off very easy with minimal rubbing,
the writing slate works best when using a wetsuit.it is less prone to move about when stroaking your arms underwater,,when it is used mounted over the skin it tends to slip down towards the elbow. the pencil should be changed to one with a heavyer graphite as it is hard to read under water.other than that it works well.also the slate cleaner works very well and only need a or two to clean the slate.
one application can be used a couple of times.
doesnt leak any water
best mask found so far,very comfortable fits most faces very well.
