I got one off amazon and reallllly glad I did. Saves me a ton of time. I also use it during packing up to blow off sand from the board and my gear/feet. I also got an inexpensive BT radio that is waterproof. It works surprisingly well! I'll link both (if possible), I tend to go overboard researching everything before buying so figure might as well share the spoils lol
