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.

 

 　

A double gauge console – pressure gauge and COMPASS+ dive computer – which is more compact than conventional three gauge console.

 

The dive computer is positioned slightly angled so the information can be read more conveniently.

Shock absorbing TPR boot provides excellent protection of its important contents.

Pressure gauge maximum reading:  (5000psi).
