  • Page 2: Warning

    The density of each body of water is different, before operation in a new body of water, adjusting the weight of the ROV is necessary to avoid damage to the ROV or property around it. Each DTG2 ROV is equipped with ballast weights to place under the handles or on the bottom of the ROV.

  • Page 4: Safety Precautions

    Safety Precautions Never attempt to swim after a stalled DTG2. Do not get in the water for any reason to retrieve your DTG2. Return the DTG2 by gently pulling it back to the boat by the tether. In cases where the tether is snagged or severed, contact a certified diver to perform the retrieval for you.

  • Page 6: Delivery And Inspection

    Deep Trekker support or your authorized Deep Trekker Dealer for assistance. The DTG2 is shipped to you with the two shipping set screws in the locked position, the DTG2 will not operate with these screws locked. This ensures that the rough motions associated with the delivery service do not damage the internal frame and the servo motor that turns it.

  • Page 7: System Overview

    DEEP TREKKER DTG2 USER MANUAL System Overview The DTG2 ROV is designed to operate in fresh or salt water between the temperatures of -5C [23F] to 45C [113F]. This unique ROV incorporates internal/onboard batteries, so the system is completely portable with no top side generator or box required. The tether is also much smaller and lighter than a tether designed to carry power.

  • Page 11: Calibrating The Buoyancy

    Calibrating the Buoyancy The DTG2 ROV is shipped from the factory calibrated for fresh water use. To adapt for salt water, simply add the provided ballast plates, as shown in Fig. 4, evenly to the top mounting points or bottom mounting points.

  • Page 12: Launching Your First Dive

    There should be no wind or current present. Lower the DTG2 into the water by the handles, or gently lower it in by the tether. Do not throw the DTG2 into the water for risk of striking an object.

  • Page 13: Operation

    – these will not shut down automatically. Driving Controls As shown in Fig. 5, the motion of the DTG2 is accomplished with only 2 joysticks. The left joystick completely controls the thruster in an intuitive manner. Driving the DTG2 on a lateral plane.

  • Page 14: Thruster Trim

    DEEP TREKKER DTG2 USER MANUAL Thruster Trim The right and left thrusters can be trimmed to ensure the ROV drives straight when the joystick is full forward. Small variances in the ROV can pull it slowly to one side. To adjust the thruster trim, place the ROV in an open body of water with no wave action or current.

  • Page 15: Primary Flood Lights

    DEEP TREKKER DTG2 USER MANUAL Primary Flood Lights The primary flood light button, shown in Fig. 3A, turns the primary flood lights on and off. The primary floodlights are located inside the ROV mounted below the camera. Auxiliary Flood Lights (Optional Equipment) The auxiliary flood light button shown in Fig.

  • Page 16: Pitch Lock

    DEEP TREKKER DTG2 USER MANUAL Pitch Lock By default, when the unit is turned on, the pitch angle of the ROV follows the present position of the pitch joystick (the right joystick). Since the joystick is “spring return to center”, the body will also return to a 0 degree (horizontal) pitch when the operator’s thumb is off the joystick.

  • Page 17: Led Indicators

    Once the debris is removed, turn on the system again and test the thrusters in and out of the water. If the thruster error LED turns on again, contact Deep Trekker support or your authorized Deep Trekker Dealer for assistance.

  • Page 18: Tether

    It is advised to have an assistant managing the tether as the ROV demands more let into the water, or pulled back out of the water. Leaving too much tether in the water will cause excess drag on the DTG2, and not having enough will restrict the ROV manoeuvrability.

  • Page 19: Shutdown

    Trekker Dealer for assistance. Wipe down the ROV with a towel or rag. If the DTG2 has been used in salt water it is advised to rinse it with fresh water to ensure it does not corrode. After the fresh water rinsing, wipe the ROV dry. If the optional carry case is used, do not close the lid after use.
  • Page 20 Note both the ROV and Controller chargers are ‘smart’, meaning there will be no harm in leaving the chargers plugged in overnight, or giving your DTG2 a quick charge for some extra life on your next dive. Leaving the batteries fully drained for long periods of time will cause permanent damage. We recommend fully charging them every 6 months to ensure they do not fully self-discharge over time.

  • Page 21: Storage

    It is recommended to charge the battery at least once every 6 months if the unit is not being used. If the ROV is stored in a sealed compartment such as the optional carry case offered by Deep Trekker Inc., the ROV and tether must be left to dry off 100% prior to sealing the case shut.

  • Page 22: Transporting

    DEEP TREKKER DTG2 USER MANUAL Transporting *It is important to store and transport your DTG2 in a fashion that does not rock the pitch system back and forth. This will cause premature failure because it is working the gear motor and gear train. This sort of failure is 100% unwarrantable.
