Compatt 6 Midi shares many of the same features and acoustic output capabilities of a Compatt 6 Standard but is offered with a small, long life Lithium battery pack and shorter length housing. The design lends itself well to acoustic metrology campaigns where the shorter length and optional integrated inclinometer, reduces the lever arm and therefore errors for offsetting transducer-to-endcap. Compatt 6 Midi is available with a wide range of integrated sensors and bottom endcap options including; acoustic release, sound velocity and inclionmeter.
