Padded Protective Case for 9" Marine GPS/Fishfinder Units

welcome and thank you for watching today's video i'd like to show you our nautilus lifeline marine rescue gps units which will alert surrounding boats up to 35 miles away of your location in the event you are separated from your dive boat these little transmitters use both direct signal calling also known as dsc and the automatic information system known as ais these newer units are smaller than the old ones as you can see they don't require registration with any government agencies you could replace the batteries yourself by using two cr123 batteries and they also still come with the same ways to attach them they come with a little pouch you can put them in your pouch you could put a lanyard onto them to keep them in a bcd pocket and they're very easy and convenient to carry with you to replace the batteries is very simple open the top and you'll see two screws on the top you unscrew t
