Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

  4. Determine and analyse beams in relation to transducer settings
  5. Use phase and amplitude multibeam systems
  6. Analyse returns in the context of marine floor type, angle of incidence and backscatter from within the water column
  7. Determine sounding density and object detection capability as functions of system parameters
  8. Determine and use suitable mounting structure and location for transducers according to manufacturer instructions
  9. Determine and analyse error sources for phase and amplitude detection modes
