While they're fun to drive and may feel as easy as playing with toys, the Deep Trekker products are commercial grade units that are built to last in the harsh ocean environment. Used by aquaculture, oil and gas rigs, police rescue, infrastructure agencies and deep water explorers, these units are relied upon to dive deep and return clear pictures on a live feed topside. The fact that they make it fun is a bonus!
A key requirement for infrastructure inspections is to ensure that water turbidity is not increased when working on the bottom of a structure and to maintain visibility. This can be especially important when working in drinking water tanks. The patented pitch system used by the Deep Trekker ROVs means that we can descend and ascend without clouding visiblity that affects video capture or delivering silt to end users down the line. Conversely, when we want to 'brush' silt away from the bottom of a metal structure to assess for corrosion, we can choose to do so in a controlled way.
The DTG3 ROVs are rated to 200m depth while the DTX3 Revolution and the DTPods are rated to 305m depth. Both the submersible utility crawler and pipe crawler are rated to 50m depth. You should always keep to the depth rating of the unit you are using.
Yes - in fact, we worked closely with Deep Trekker to develop the vacuum cleaning unit that is used so widely around the world for cleaning out water tanks. The secret to cleaning liner tanks without damage is being able to turn without scrunching the liner under foot, or under wheel in this case. The rear trailing wheel on the utility crawler means only the front wheels need to be powered. This also allows zero radius turns, which is very important when working in confined spaces.
No - the wheels have been designed so that they are only magnetised at the point where contact is made with the ferrous surface. Once the wheel passes over the surface, magnetisation ceases and any rusting material gathered on the wheels falls off. This means that metal surfaces can be inspected without binding the wheels and without damage to the surface - except for the loss of corroded material, which is consistent with all other magnetic crawlers.
