Peer beneath the surface of the sea with this bathyscope, or underwater viewer. The bathyscope is a great tool to help teach children about lake biology. The bathyscope gives you the view from snorkeling without getting wet. The round bathyscope disassembles into three nesting pieces for compact storage.
The underwater viewer is the fisherman's friend. Far less expensive than electronic fish-finders, it is simple to use and easily transportable to any boat. Use the bathyscope to get a sense of what the bottom looks like, visibility, and the overall fishing environment.
This underwater viewer is simple, inexpensive, practical and fun!
