Tour skating also requires that you have poles specified for nordic skating. Ski poles or cross country poles do not have the same abilities as the ice poles are heavier and will be able to penetrate the ice and give support. In addition, the poles will provide extra safety as the ice poles have an extra sharp spike that you can test whether the ice is solid enough to skate on. We also recommend bringing ice spikes, a cast line and a whistle. Ice spikes are two steel spikes that you should have available around your neck. In that way you can use them to get up in case you fall through. A cast line is a rope with extra weight that can be thrown out to a person or up on land to get help to get ashore.
