Precision searching underwater is critical. Many of the tools that we use help bring us to a suitable dive target. But once we are there, we need to maintain our precision in our dive profile.

To do this, we equip our divers with wrist mounted sonar receivers and then drop a sonar transponder into the water. The wrist units can then provide real-time distance and direction data to the diver so that they know exactly where they are in relation to the transponder.

Not only does this make searches more effective, but it also provides a measure of safety as divers know where the boat is, even in poor dive conditions.
