At IST, we have taken our tried and proven GP-3000 DATA+ down the evolutionary path. Now, we have the new GP-4000 COMPASS+ dive computer, which despite the similarity in appearance to its older cousin, COMPASS+ is indeed a more powerful instrument in comparison and all divers will appreciate its practicality and sophistication.

 

 

As its name suggests, GP-4000 has a built-in digital compass that can be activated with a touch of a button and works at angles that would be impossible for a conventional unit. The new dot-matrix screen gives a better visual presentation of information and dive profile. Users can also programme (up to) 3 Nitrox mixtures before a dive and change between the gases mid-dive.
