Jackstay Search Method Advantages/Disadvantages


The jackstay search method includes ROVs or divers going across the jackstay. It’s used to direct divers. It is a line between two anchors that are fixed in the earth. In other circumstances the jackstay could be used to guide commercial.

Divers who travel between and to workplaces underwater, or to support of transporting equipment and other materials in and out of their workplaces underwater or to facilitate the transportation of materials and equipment. Variations on the Jackstay Search Method

Jackstay Search Method Advantages

    • The Jackstay search technique is highly accurate since there are lots of edges that are overlapping in each sweep.
    • It’s easy to change divers midway through the hunt without having to return.
  • This method for searching for jackstays is efficient in large, open-water environments.

Jackstay Search Method Disadvantages

  • The jackstay method of searching requires a substantial amount of equipment to set up effectively.
  • The jackstay technique could be difficult to master , particularly for new or experienced rescue divers. It may require more in-depth training.
  • Although precise and thorough, the method of searching using jackstays can be slow-going.


In order to utilize the grid-based search technique, teams have to create an outline around the space of search. With markers buoys teams create search squares that cover all of the area searched. Like other techniques in that the dimensions of the search squares are determined by their visibility and the extent to which the area will be searched. After search squares are constructed every one of them is examined. Once the search has been finished for all squares the users will note down any information relevant. The process is repeated for each square within that search zone.

Grid Search Variations

The most popular variant that grid searches are grid Google underwater search with the compass. In this kind of pattern, a diver or vehicle can traverse parallel lines using a the compass bearing as well as its reciprocal while performing the eye search. The parallel lines are usually able to overlap, which is necessary to ensure precision.

Grid Search Method Disadvantages

  • Although the highly precise Grid searching is very precise, it can take quite a while to complete.
  • Grid search techniques are complex and require expert divers.
  • Grid search techniques require an the use of a lot in terms of tech.


The search using snag lines is an effective method of locating large targets within a smaller area. If the dimensions and shape of the target are acceptable with the goal in good condition and in good condition, the snag-line method of searching can be an efficient method to find something.

Snag-Line Method Advantages

  • The Snag Line Search method is highly effective for big targets, like sunken cars, aircrafts and boats.
  • The Snag-line method is extremely fast.
  • The snag line doesn’t require lots or equipment.

Snag-Line Method Disadvantages

  • The snag line method is effective with large objects. But, it’s not ideal for targets that are smaller.
  • The snag line technique could cause damage on the sea floor or even the bottom of the lake.


  • This is an idea that the person is situated in an area which is the same as the depth of the ocean.
  • Particularly in cases where the victim’s last place of residence is near an ocean shoreline, boat dock or pier the quick search is conducted by the first two divers. Then, the other team members begin to download pocket TV app to install other equipment.
  • This is particularly useful in water bodies that are susceptible to risk.

Quick Search Method Advantages

  • The fast search method can help find victims fast near the shoreline dock, pier or shore.
  • A search that is conducted with the jackstay method, divers begin with an anchor and continue to explore their line until they reach an additional anchor.
  • Once they have reached an anchor that is second in size, it gets moved laterally , causing the shift of this line.
  • The distance at which the fixed point moves can be calculated by condition that the sea has, its turbidity as well in size of the item.
  • Once the anchor is demolished, the diver switches orientations and also explores an area following the direction which leads back to the anchor that was originally used. This process continues until the entire area is fully explored.

Variations on the Jackstay Search Method

  • When the water body that is to be examined is very small or shallow, the jackstay might be moved by the team on top of it, while divers.
  • By lifting the jackstay and then moving the straight line to it’s original position , the surface team could efficiently transfer the line to that of the diver.
  • Another option, which is mentioned within the J search method, is to have the ROV or diver start right at the very beginning on the searching line every time.
  • After the line sweep is complete at the end of each jackstay, the precise jackstay’s position is reset every time until at the completion of the sweep, the line is now straight returning to its original position.
