Ewa Marine Flexible Camcorder Housings are manufactured to accomodate most popular camcorders on the market today (see chart).  Although camcorder housings are pressure tested to 150 feet, recommended depth is no greater than one atmosphere (33 feet).  Going deeper is possible with a continuously running camcorder, but this is not recommended.  At 40 feet or below, water pressure has a tendency to affect the tape.  Also, no camcorder should be taken below this depth, since camcorders are not designed to withstand higher pressure.  When possible, preset as many controls on your camcorder before inserting it into the housing. To match your camera with the correct Ewa-marine housing, call us at (631) 242-6801, or email us at rtsinc@erols.com or link to www.ewa-marine.de.
