Line Markers in Diving

In the past, roads, tracks and sporting fields lacked the adequate guides needed to make their use easier for the pedestrian, driver and athlete. Roads meant for driving were just tarred with the divers expected to know that one lane was for incoming cars and the other for outgoing. If the road was a one way road, there was no way of knowing that unless there was a visual guide stating so. For the running athlete, maintaining his or her own lane while participating in a running event might be futile as there was no visual guide clearly stating which lane belonged to him or her. For the footballer, there was no clear demarcation of which end of the field belonged to his team and his opponent, he had to rely on his ability to remember where the demarcation was meant to occur.

Thanks to modern technology, issues like that are no longer a worry as man has come up with line marking that are better able to perform the task. Due to the difficulties experienced above, the manual method was developed back in the days involving chalk and the use of a rope to measure the required space out but this method was susceptible to errors and could not be trusted. The need to develop more on this brought out the line marking. Avail the services of the line markers from Melbourne.


Line marking are not restricted to the use of roads and lines but can be used in both cave and wreck diving serving as visual and tactile guides. These markers are also referred to as line arrows, directional arrows, and cookie and doff arrow. These line markers are known to be used in Australia as well as other countries that encourage the act of diving. For line arrows, they mark the location of a jump location especially in cases where there are two caves close to each other. In cases where the divers are not able to see the arrows, they can detest their meaning by just touching them.

The typical arrows or line marking used in diving are:

• Line arrows: depict directional information and also point to the nearest surface with breathable air.
• Cookies: these are non-directional but are placed by the divers themselves to mark spots which they want to return too or alternated exits. Although it is a good way to keep track of locations especially in confusing caves, it can be confusing when there is no visibility as it does not have a clear shape.

Markers are important as the denote and explain directions for keeping safe.
