Hazer,
Excellent advice from all, and if you are willing to go that extra mile in your prep then check here:

I am not affiliated with this company but I will certainly vouch for the operator. You will not find a more knowledgeble, suitably qualified/experienced and downright friendly guy to help you with all aspects of prepping for ADF flight screening.
Happy landings.
