To help eliminate the spread of aquatic invasive species (AIS), Waterworks/Lamson created this Gear Shower, which you fill with tap water from home and use to rinse away all visible material from gear when you finish fishing. It is easy to use: simply lower a vehicle window an inch or more and hang the shower. Gravity pulls the water through a shower head with an on/off switch. The shower has a 2.2 gallon capacity, and money from each purchase is donated to the Clean Angling Coalition. Retail is $49.99.
