What can an ROV do?

Frequently Asked Questions

• How deep can the ROV go?

  The DTG3 ROV is designed for a depth of 200m (656′), while the REVOLUTION and PIVOT are rated for a depth of 305m (1,000′). Every system we sell is tested in our pressure tanks to ensure it meets its designated depth rating.

• How long do the batteries last? Is there a Direct Power option?

  Deep Trekker ROVs and controllers can operate for up to eight hours without needing a recharge. The charging time for the DTG3 and Bridge controller is only ninety minutes, but the batteries can be charged up to eighty percent in just forty-five minutes. The controllers can also be plugged into a power outlet during use to extend operating time by several hours.

  The REVOLUTION batteries fully recharge in three hours. They are also swappable, allowing you to keep a spare set charged to stay operational throughout your mission. Additionally, we offer a topside power module if you need continuous operation, enabling you to power the REVOLUTION from a 110-240 VAC surface power source.

• What kind of camera is in the drone?

  Our ROVs are equipped with a full-color 4K HD camera. The footage is always displayed in this high quality!

• Can I connect the controller to a larger monitor while diving?

  The ROV’s handheld controller features a 7-inch LCD screen. Its high resolution and bright display provide a portable, high-quality viewing experience for a single operator. However, there are times when you may want to display video footage on a larger monitor for a group of viewers. The handheld controller is equipped with an HDMI output, as well as Ethernet, SD, and USB ports, giving you the flexibility to connect to other devices. Alternatively, the ROV records video and photos on an SD card, which can be easily removed and viewed on other devices.

• Can I lift and lower the ROV using the tether?

  The tether has a tensile strength of approximately ninety kilograms, so lifting the ROV by the data cable is not a problem. You can lower and raise the ROV using the handle or the tether and retrieve objects with the grabber arm by pulling up on the handle.

• How much weight can I lift with the gripper?

  Grabbing and lifting objects underwater is a common application for Deep Trekker ROVs. There are a few different ways our customers use our vehicles to lift objects. The first method is to grab and pull the object up by the handle. The tensile strength of the data cable is 150 kg (300 lbs), which is your weight limit when pulling up by the cable. When you grab an object and swim with the ROV, the limitation depends on the size of the object. The DTG3 can lift up to about one kilogram, while the REVOLUTION can lift up to about four kilograms. The last common method for recovering objects is by holding a carabiner in the gripper and hooking or tying the object to a line, which is then used to recover the object. In this case, you can rely on the tensile strength of the cable as the maximum weight limit.

• Can I add my own accessories, such as a neutrally buoyant camera?

  Yes, as long as the accessory is within forty grams of the neutral buoyancy, it will not affect the ROV’s ability to maneuver through the water. If the object is heavier, the buoyancy will need to be adjusted for a neutrally buoyant drone.
