Similar Terms: Maximum Depth,Useable Depth
Many marine electronic manufacturers will talk about maximum depths a Sounder should reach.
To our Way of thinking that is a bit like a car's speedo showing a maximum speed of, say, 250kph. That does not mean you will get that speed (unless you are travelling down hill with a very strong wind behind you!)
There are many variables that affect the depth that a sounder can see the seabed.
- Amount of salinity in the water
- Beam angle
- Transducer Frequency
- Output power
- Hull shape & Bubbles
- Type of Transducer - In Hull, Through Hull or Transom mounted
So when you see the term 'Usable Depth' this is a more realistic idea of what you can expect in most conditions - however there will always be an exception to the rule.
