Despite its small size, the Fusions are powered by a micro-processor running a complex software.
The software converts the data coming from the dive computer in order to be readable by our mobile apps.
The Fusions do not need any batteries at all! As long as your dive computer and smartphone/tablet work, your Fusion works too.
Several reasons:

  • Apple does not allow 3rd parties to make accessories for dive computers. Only the dive computer manufacturers are allowed to do that.
  • With a universal USB interface it is possible to support older iOS devices that use the 32pin connector.
  • The FusionIR works on Android, Mac, PC and Linux, a USB interface is the perfect fit for all
No, the Fusions are only compatible with DiveMate for iOS and DiveMate for Android. The FusionIR supports third party software running on PC and Mac. But with the DiveMate Apps you are able to synchronise your data with most dive log book applications.
Yes, you can use it on your Android device with DiveMate for Android, or simply plug it into your PC or Mac and use it with third party programs.
No, there is no need for the FusionUSB on other platforms than iOS. Dive computers with a USB interface can be connected directly to Android devices running DiveMate for Android or to PC and MAC running third party software.
Although it looks like a USB stick, it is not fair to compare prices that way. The Fusion is a complex piece of hardware/software and a niche product produced in small quantities.  Nevertheless, all initial costs for production and development must to be covered.
Processing of orders takes 2 to 3 business days. The Shipping times vary from country to country. Average shipping times can be found on the website of Deusche Post (german parcel).
Please pack up the Fusion and send it to this address:
LiquidApps UG
Liebigstrasse 20c
80538 Munich

Please label the parcel appropriately for customs with a CN22 form and state “product return”.
Once we receive it we will refund the amount.
