Is the Fiobuoy’s jaw and pin strong enough?

In traditional acoustic releases, the release mechanism needs to support the payload weight. Whereas, with the Fiobuoy, the rope (with a breaking strain of 5,000kg) not the jaw and pin, holds this weight. The Fiobuoy’s jaw and pin only needs to hold a maximum of 8kg of buoyancy plus some tidal drag. The jaw and pin has also been tested to withhold several times this load.
