The Electric Alpha Numeric Registration Identification Watercraft is a game-changer when it comes to clearly and easily identifying your watercraft... Based on our own experience we found it to be highly effective in preventing mix-ups at busy docks. The automated system is also a huge time-saver when it comes to filling out registration paperwork. The only downside is that it may not be suitable for individuals who prefer more traditional decal-based identification options. Overall, we highly recommend this product to anyone who wants the best in watercraft identification technology..
