We like a few great things about this product. It's small, the battery lasts for 12 hours and it is completely waterproof. We are planning to buy a kayak for fishing some of these lakes here in Florida and this cool contraption would be the perfect addition to our fishing gear. It looks like it is easy to use and it will give us quite an advantage in any of the fishing locations we are planning. We checked everything out on YouTube and this small little gem is going to make our next fishing trip a blast.
