Don't buy it for tide prediction
Reviewed by Ian Bambury from Surrey, UK
I've just packed this up to send back. As a tide predictor, it is useless. I put in a high tide, checked the next one and it was 45 minutes out. A week later it was unrecognisable. Find one that uses time of day, latitude and lunitidal intervals.
It is just a wrist watch pinned to a holder. It would be fine hanging off a rucksack strap but I wouldn't give it much of a chance hanging off a belt loop if you caught it with your seat belt, for example.
I'm going to find something else.
