Loose Leaf
GNS has redesigned the Admiralty List of Lights & Radio Signal publications to be delivered to you in a loose leaf format within a ring binder. Once you subscribe to this service you will receive the initial printed folder, after which we will send you a weekly pack containing corrected replacements for all pages affected by that week's Notices to Mariners. Once received, simply replace the original pages in the ring binder with the corrected copy.
