Thanks

Sorry if this has been covered before but can I attach a bubble tester inside my gas locker by drilling and tapping through the locker wall, to the outside of the boat or do I need some kind of weld on bracket. If using the drill and tap method the hole would be on the same side as the locker drain hole if that makes a difference

We have one of these connected directly to a 100w solar panel. chills during the day and stays cool overnight. In the winter when cool box is not needed the solar panel is parallel connected to the battery charging panel for extra charging capacity.
