Your shelter will be your home during your night session and must try to have it as functional and organised as possible. Regarding installation, a bivvy with a bedchair act as a basis for shelter in case of rain and as a place to rest during the first bouts of fatigue. The bivvy is also the ideal place to do your assembly if needed. It is in fact possible to have sufficient lighting on the inside without alerting any fish lurking nearby...
Do not cut corners on your bedchair. The wait can be long indeed so you should take something with maximum comfort to make this period easier.
To keep rodents away, keep your bait as high as possible so they aren’t nibbled on.
You should prepare several baited fishing leaders in advance to make the most of your time. Put them in a fishing leader bag specially designed for this purpose.
As regards electronics, the detector batteries should be checked to avoid more difficult night manipulations.
Finally, remember to keep clear access to your rod stands so you don’t trip when leaving.
