We weren't originally able to use this product due to the fact that it was winter, and this is for water, and we live in a very cold state. I purchased this as a gift for my dad and his wife because they just bought a brand new boat. This has lead to many fun competitions on the boat this summer between family members, and friends. It's fun to golf on the lake, and you don't have to make a tee time. We thoroughly enjoy spending funday sunday on the lake and this makes it a little bit more fun. Instead of fishing... not for everyone.
