Suunto DM4 with Movescount software allows you to both transfer your dive computer’s logbook data to your laptop for detailed analysis and upload detailed dive plans from your laptop to your dive computer. Suunto DM4 with Movescount is free to download and will be updated automatically when you are online.

Before you begin a dive, you can easily plan dive profiles, gases, and back up plans on your laptop using DM4’s detailed graphical planner and export them to your wristop dive computer using a compatible USB cable, ready for your next dive.

With Movescount you can track and share your dives online, and easily compare, edit, and summarize your dive data. You can also enrich your dive Moves with your video and pictures, and share them on Facebook and Twitter.

You can transfer data such as dive profiles, maximum depths, temperatures, air consumption, and nitrox data directly from your dive computer to your laptop. You can also enter dive locations, names of your friends, equipment, and other comments – just as you would do with a conventional paper log.

The simulator function helps you gain greater understanding of decompression theory and computer-assisted multilevel diving, and is also an excellent tool for dive instruction.
