Safety, Signalling & Tools for UK Divers

Safety underwater is non-negotiable. In challenging UK conditions, having the right signalling devices, DSMBs, cutting tools, and attachment methods is essential. Our guides help divers select the correct safety equipment, deploy DSMBs effectively, choose reliable cutting tools for wreck and kelp environments, and maintain essential hardware like bolt snaps and spools.

This section covers:

  • DSMB and spool selection for UK diving
  • How to choose cutting tools and placement strategies
  • Signalling techniques from surface to depth
  • Essential attachment hardware like bolt snaps and retractors
  • Equipment checks and maintenance
