What people are saying

“We run fishing and sealife tours and dipping in the LSTN2 over the side has proved a huge hit with our guests. It’s especially useful if it’s slow and the fish aren’t biting!”
James, Mull
“Seeing dolphins when we’re out sailing is a real treat. Being able to hear them too is pure joy!”
Brian, Sailor.
“Drop the hydrophone in and start listening. It really is that simple. We’re already using it as part of our awareness raising work to bring the underwater world to life for passengers on Dolphin Survey Boat Trips. Hearing dolphins in the wild really is something special and listening to the sounds in the sea can be a real eye opener. This is a fantastic piece of kit that adds a whole new dimension to the underwater world that surrounds us. You should certainly find a place aboard your boat for it whether you’re a regular boat user or a researcher. You’ll enjoy how quick and easy it is to use”.
