An embodiment of the invention is directed to an electronic caliper which combines positioning and measurement in one unit without the use of hydraulics for subsea use. In certain embodiments, several attachments can be affixed to accommodate a range of measurement tasks. In a preferred embodiment, one jaw is adjustable and the other, or opposing, jaw is fixed to a mounting structure. The jaws typically allow for the removal and replacement of other attachments. In another embodiment, the unit communicates to computer software for position control, precise indication and clamping for adjustment. In a preferred embodiment, computer software displays all feedback via laptop computer on surface. The caliper is maneuvered to a position proximate an object and used to measure a predetermined physical characteristic of the object. The measurement can be displayed using a computer with control software.
