 ===Set-up:===
 Simply plug the XLR that is attached to the hydrophone into an amplifier or sound recording device. Media Loan sound recorders, such as the [http://wikis.evergreen.edu/computing/index.php/Olympus_LS-100_Multi-Track_PCM_Recorder_Operating_Guide Olympus LS-100] and [http://wikis.evergreen.edu/computing/index.php/Zoom_H4n_Audio_Recorder_Operating_Guide Zoom H4N], require separate proficiencies from the hydrophone prior to checkout. <br>'''SAFETY TIP''' - '''Do not attach the amplifier/sound recorder or the hydrophone itself to your body.'''Hold it in your hand, or set on a stable surface. You can use various devices to extend the hydrophone outwards from the recorder before submerging.

 For best results, turn off the engine and drift – otherwise engine noise will be picked up.  You can lift the hydrophone and set it so that your boat hull blocks sounds from other boats that may be nearby.  To minimize sounds from your own boat, such as waves, you can use various devices to extend the hydrophone outwards (a fishpole, float, etc).

 ==How to Use It==
 As soon as this hydrophone is submerged it will pick up sounds and is best used at least 7ft deep.  The omnidirectional pattern of the hydrophone means that the orientation is versatile.
-===DESIGN===
+===Design===
 The DolphinEar/PRO hydrophone is an omnidirectional microphone.  It was designed with unique large aperture MPC piezo-electric element that responds to sound pressure variations over a wide dynamic range.  It is completely encased in a special epoxy casing, which makes it far more rugged than most other under-water microphone designs.
