Here you’ll find the logbooks of my current leisure activity’s. For some of my leisure activity’s a logbook is required by German law (aviation), for the others I just keep it for fun and memorization. If you’ve any questions about my activity’s feel free to ask.

• Climbing Logbook Logbook of my alpine climbs (with date, time and UIAA rating)
• Diving Logbook Logbook of my dives
• Aviation Logbook Logbook of my flights (none so far)
