Select a start point to your route that is convenient for both reaching the bank and standing to record bats. Clearly mark this as your first spot on the map. (Before starting you may wish to walk 1km along the waterway and then mark out your route so that it takes you back the way you came. This will mean that spot 10 will be close to your transport and you will not have such a long walk in the dark at the end when carrying out evening surveys.)
From this starting point walk along the river/canal, pacing out rough 100m intervals as you go. After each 100m, select the nearest point at which you can see the water's surface. Repeat this until you have selected a total of 10 such points, or 'spots'.
Do not choose spots because you think they will be good for bats, as this will bias the results - just stick to points that allow you to access the bank and record bats.
Choose stopping spots that are accessible and can easily be found again.
Describe the spot in relation to a feature or landmark to enable you to recognise it.
Watch the video clip for an example.
Use permanent/long-term features as landmarks wherever possible. A permanent feature would be something like a mature tree, a gate, opposite a lamp-post or a building.
