This is quickly becoming our new standard. A heavy hitter, 120 Watt!. Very good for application on the lid of the box-cooler, on the sea-chest or on the hull. Its vibrating surface is directly glued to the object to be protected. This model can also be used with an aluminium installation adaptor (with a bigger diameter than the 100Watter). The adaptor can be machined in the same curve as e.g. piping or a bucket strainer on which the transducer is to be installed.
