Range Switch of Echo sounder
- Could be between 0-10M, 0-20M, 0-50M, 0-100M, 0-200M, 0-1000, etc.
- Check the approximate depth in the vicinity of your fix.
- Start at a range which is just little more than this depth. (if the depth is 98M, choose 0-100M)
- Look out for an echo blip or a marking.
- To coax out the echo, you may have to manipulate other controls.
- Once observed, shift to one range scale higher.
- Observe the echo against the enhanced range scale marking.
- It should be the same as the earlier readings.
