1. A device configured for monitoring strain of an elongate member deployed underwater, the device comprising:
a first clamp configured to embrace and couple to the elongate member at a first axial location,
a second clamp configured to embrace and couple to the elongate member at a second axial location separated from the first axial location,
a sensor actuator member coupled to the first clamp and the second clamp, wherein the sensor actuator member is coupled to the first clamp through a first coupling that comprises a ball and socket and that permits the sensor actuator member to move angularly with respect to the first clamp, and
a sensor which is responsive to an angle between the first clamp and the second clamp.
