How to use the DiverLog+ App to pre-plan dives with the Pro Plus 4.0 Dive Computer?

You must have a smartphone with the app installed and the Pro Plus 4.0 nearby to initiate the first sync. Start by pairing the device to your phone to enable the data transfer.

Pro Plus 4.0 gas mix support and Bluetooth connectivity for pre-planning

The Pro Plus 4.0 supports adjustable dual Nitrox mixes and gas mixes, which allows the app to calculate specific gas profiles for your pre-plan. Our comparison of the scuba diving computer options we evaluated confirmed that the device supports firmware updates and Bluetooth, which are essential for maintaining the connection between the hardware and the software. Because pre-planning ensures your gas limits and deco stops are calculated before you enter the water, verifying these settings in the app prevents a situation where you have to recalculate complex gas mixes while underwater. The app allows for the input of specific gas mixes, but the data does not state if the software requires a specific user account profile to be created before pushing the plan to the computer.

Comparing the Pro Plus 4.0 to Other Scuba Computers

The Pro Plus 4.0 is a wrist-mounted computer that tracks your depth and gas levels while you swim underwater. Divers who prioritize high-end features like dual algorithm adjustments and specific gas mix customization will find this model suitable. If you require a simpler interface or a lower price point, you may prefer a basic dive computer that does not include Bluetooth or smartphone integration. Choosing a device without these connectivity features means you lose the ability to share dive logs instantly or pre-plan complex gas mixes on a larger screen.

Many new owners ask about navigation tools, so we clarify if the Pro Plus 4.0 includes a compass.

If you need a high-end computer with advanced gas mixing capabilities and smartphone integration, the Pro Plus 4.0 is the correct choice for your setup.
