I log every dive reguardless of time or depth.
If for no other reason to record the process of the dive. I recently tried to dive in Venice Fl. and Had to call the dive due to bad vis. Well I logged the shortest dives I ever done 15 ft for 2 min. 3 times that day. The reason I logged them was to record the reason for the called dive, buddies I dove with, equiptment I used. Date and weather conditions. If I suit up and enter the water It goes in the log book for future referance. A log book is a history of your diving experiances for you more than anything else. It gives you something to look at as you build up your diving experiances.
