Tisch Spearfishing

Tisch Spearfishing is a dive instrument for the Croatian Adriatic. It answers one question before you drive to the coast: is it worth getting in the water today?

WILL YOU SEE ANYTHING
An hour-by-hour visibility estimate built from wave height and period, wind, rain over the last days, sun angle and the depth you dive to. Nothing is dressed up: where the model is uncertain, it says so.

THE DIVE WINDOW
The hours worth diving, marked on a single bar. Wind, gusts, wave height and period, sea and air temperature, tide, sunrise and sunset, and the moon - read as one answer instead of eight numbers you have to combine yourself.

WIND FROM THE CROATIAN MET SERVICE
Wind and gusts come from DHMZ's ALADIN-HR model at 2 km resolution - a national forecast built for this coast, not a global grid that cannot see between the islands.

SHELTER OF YOUR SPOT
A 24-ray rose showing how far open water reaches from where you stand, in every direction. Behind an island in a bura, exposed in a jugo: the rose shows which is which before you pack the car.

DEPTH CONTOURS, BUNDLED IN
Adriatic depth contours ship inside the app, so they draw even when the signal does not reach you at sea.

47 ADRIATIC SPECIES
Minimum sizes, closed seasons and what the spearfishing rules actually say for each one, plus how to approach it. The app tells you whether the fish in your hands is legal where and when you caught it.

DIVE LOG
Every dive keeps the conditions it happened in - depth, time, visibility, wind, the catch. Over a season it becomes the only record of which conditions actually worked for you.

FREE FOR SEVEN DAYS
Use everything for a week. After that a single purchase unlocks the app for good. No subscription, nothing renews, no ads, no account, no tracking - and nothing you enter leaves your phone.

The app covers the Croatian Adriatic. It is a planning tool, not a safety device: the sea decides, you decide, and the numbers are only an argument.
