TUSA Diving LOG is a diving logbook app, which enables you to upload log data from TUSA IQ1204 DC Solar Link to your smartphone using Bluetooth® SMART. The TUSA Diving LOG App has many customizable functions to record the details of your dive. Information such as entry time, exit time, dive time, maximum water depth, average water depth, water temperature, air consumption, and much more can be recorded. Customize your dive log by recording dive point locations using maps, add photos, and capture signatures from an instructor. In addition, detailed water depth and warning information can be recorded at intervals, and uploaded to your app. Also you can easily export dive log information as images to share on Facebook, Twitter, or other social media. TUSA Diving LOG can be used independently of TUSA IQ1204 DC Solar link to record basic log information.

Loved it! ...Until it stopped working

Dunno why but after updating to iOS 11.3 I completely lost the ability to connect to my dive computer. I’m an instructor and dive almost daily - please find a way to fix it ASAP!
