38 +If you are short on magnets, you may find it easier and a lot cheaper to buy magnets in Australia. AMF Magnetics is a good retailer, and [[this item>>https://magnet.com.au/collections/shop?q=23012B]] seems to work well. It is also advantageous to use smaller magnets and store/carry them individually in your back pocket (as well as stick them to various places in your field vehicle, etc).

40 +== Animal-Proofing ==

42 +We have experienced times where foxes (or some other animal) will dig up nodes and potentially carry them off for tens or hundreds of meteres. Being sanitary with the rope handles (e.g. not getting food grease on them) seems to help, as well as spraying the nodes and handles with methylated spirits et al. when deploying. There are other specialized products available depending on your environment.
