Frequently Asked Questions
We know you’re wondering, so here are the top questions everyone asks
Who Are You?
When was Deep Trekker Inc. Founded?
Deep Trekker was incorporated in 2010.
Where is Deep Trekker Inc. located?
In Ontario, Canada in the heart of the Great Lakes.
Does Deep Trekker hold any patents?
Yes, the internal pitch system which allows Deep Trekker to be fully capable using only 2 thrusters for full forward, reverse, left, right, ascending and descending is patented in the United States, with international patents pending.
Where are these made?
Our ROVs are completely and meticulously assembled and tested in Ontario, Canada by our team of skilled engineers and technologists. Every submersible undergoes a rigorous product delivery inspection and in-water pressure testing before we ship it out to our customers. Covered under NAFTA, we proudly produce a Canadian product.
About the ROVs
How deep do they go?
The DTG2 ROV line, has two depth rating options. The DTG2 Starter and Pro are depth rated to 100 M (330 ft) while the DTG2 Smart and Worker models are depth rated to 150 M (492 ft) Our larger line of ROVs, the DTX2 is depth rated to 305 M (1000 ft).
What is the ROV made out of?
It is die-cast aluminum anodized and powder coated for extreme durability in salt and fresh water. If you are diving in salt water, it’s always good to give it a fresh water rinse afterwards.
How does the ROV drive up and down?
What is the Deep Trekker Patented Pitching System? There is a reason our ROVs are spherical, we use an internal semi-circle frame to mount the batteries and electronics for the ROV, which is connected to the outer shell. When the ROV is in water, gravity holds down the internal semi-circle weighted frame, we active a servo motor, and the outer shell with our main thrusters can rotate a complete 180 degrees. This is what our patented pitching system does, and provides unmatched maneuverability to pilot the ROV into confined spaces. The camera is mounted independently, so you are able to rotate 270 degrees no matter what direction the ROV is going.
How is it powered?
We have designed a completely portable system, by putting lithium ion batteries inside the ROV and controller. With batteries on-board, there is no power going down the tether, reducing the diameter and potential drag or need to bring along a generator to your dive site.
How long do the batteries last and how long does it take to recharge them?
Our DTG2 models, will have between 6 – 8 hours of working on a 1.5 hour battery charge. For a typical inspection, you will likely get a full day’s work out of one battery charge. The DTX2 line of ROVs will operate up to 6 hours on a 1.5 hour charge. With lithium ion batteries, there is no harm in giving your ROV a quick charge before your dive, you do not need to drain the batteries completely and then recharge completely.
What kind of camera is used?
Our ROVs have a full colour 700 HD camera, designed for low light with 0.001 lux. The camera rotates around the entire body of the ROV 270 degrees. Allowing you to look up, down, behind as you drive the ROV. You may also upgrade the internal camera to 4K recording.
How does this camera do in dark water / murky water?
The camera is a low light 0.001 lux camera with a LED flood light. So it does just as well as a diver would in the water. You would be surprised how well you can see once the ROV is down there. Options for sonar systems will expand your abilities in murky waters.
Is there a light?
Yes, there is a LED flood light that tracks with the camera inside the ROV. The DTG2 models can be outfitted with our auxiliary lights that add two additional LEDs, while the DTX2 ROVs all come equipped with 4 fixed auxiliary lights standard.
Does the controller record the footage?
We offer a digital video recorder that plugs into the back video out port on the controller and records all of the footage onto an SD card. It’s about the size of a deck of cards and can fit in your packet as you’re working. The optional internal 4K camera requires no additional equipment to record.
Can I plug the controller into a larger monitor while I complete a dive?
Yes, there is a RCA cable on the back for video out; you can hook this up to any TV screen or recorder.
What is the maintenance?
Simply give the ROV a fresh water rise after a dive in salt water, and keep the batteries charged. Since we have no dynamic seals to grease or parts to replace regularly, there is very little maintenance at all.
How much current can it operate in?
Our ROVs will work in higher currents than is safe for divers. Our DTG2 line have a forward speed of about 2.5 knots. Any more current than that and the ROV will have trouble swimming against it. We recommend about 1 – 1.5 knots to operate in. The DTX2 ROVs use vectored thrusters, so will have more stability when working in current, the forward speed is over 3 knots.
Can I lift and lower the ROV by its tether?
The tether has a 150 pound break strength, so there is no problem lifting the ROV by the tether. You can lower and raise the ROV by the tether and retrieve object with the grabber arm by pulling up on the tether.
How much can the grabber arm pick up?
If you would like to grab something and then swim with it to another location, the DTG2 can swim with about 2 pounds. while the DTX2 can swim with 8 pounds. To retrieve anything heavier, you can simply lock onto the object and pull both the ROV and object back to you using the tether. The tether has a 150 pound breaking strength.
What are the sensors?
Sensors give you an on-screen display of heading, depth, water temperature, pitch, roll, camera angle, and battery levels.
Can I add my own accessories to it, such as a neutrally buoyant camera?
Yes, as long as the accessory is within 40 grams of neutral buoyancy it will not affect the ability of the ROV to maneuver throughout the waters.
