 The dive profile is often recorded in some way as part of a permanent record of the dive.Maximum depth, bottom time and any decompression required are routinely logged by most professional divers, for whom it may be a legal requirement, and by many recreational divers, for whom it is usually a recommendation of the training agencies.Recreational diving paper logbooks frequently provide a simple graphic representation of a dive profile for recording the details of a dive which are necessary for planning a repetitive dive using a specified set of dive tables.
