West Marine introduces a new signaling horn that's safe for the
environment. The EcoHORN is a lightweight, easy-to-stow signal horn that emits a 115-decibel sound
blast with more than 50 bursts
per air charge. It includes a small hand pump, so you can recharge the horn with compressed
air, eliminating the need for costly refill canisters. Prices start at $22.99.
