I am planning to buy a freediving computer, and have not decided if I should choose the D4 or the Manta/Geo. The prices I have found are about the same for the D4 and the Manta/Geo. Is any of the computers better then the other? Is it true that it is not possible to change the battery yourself on the D4, then who changes the batteries on the D4's? What computer should I choose, this is so hard!!??
Thank you.
 
Hi Xander,
yes it's truth, you must sent it to service if you want change battery same like Suunto D6. I have same problem like you. D4 has better resolution on display then Geo. Geo looks more plastic as a toy but Geo has 3 depth alarms louder and visibly then D4.
