2019 Underwater Drone GLADIUS Mini 4K ROV Review - Part 3 - [In-Depth OCEAN TEST, Pros & Cons] 

The Gladius Mini is one very good exploring tool for sure. It is probably so far the ONLY underwater ROV for consumers that actually keeps what it promises. We have used it now for some time and it is just FANTASTIC. Thanks for sharing.

I made mine even more stable by wire tying a snap swivel to the rear vertical fin and another to the tether so that the pull was directly behind the Mini as opposed to pulling on the top. This also takes the strain off of the connector in the event you had to pull it back manually.

Incredible review and location to do so. I love Hawaii and you show us how impressive it is in the air and underwater. Keep up the great content!

Awesome, great place to do an real underwater test. Looks like a lot of fun.

Wow that turtle! He totally came and checked you out ha ha that was too cool! Thank you for another great video and review!

Very in-depth as usual, brilliant,thanks Dustin 😀.

Been missing your reviews, nice to see you are back at it. You have such a beautiful place to fly with drones and dive with subs. 🤙

Especially appreciated your picture in picture and good narrative while shooting. Good production value.

Thank you for the video, some of the most incredible pictures,,,you live in paradise 👍

All your Vids are Great!! Well explained and Great Footage!! Thanks

I looks quite good. It will be interesting to see what it does in calm water. I think the fish were attracted by the colors/shape of the sub. It also moves in a similar manner.

I have no need for an underwater drone but I stayed here until the end and that is some pretty cool tech.

Beautiful Dustin, the best yet. Maybe a gimbal similar to the Parrot Anafi with the camera in closed that can move all of the way up and down.

Very cool. I love it! Thanks for sharing the experience.

Like you said, by far the best sub video and stability wise. Not to mention you are an awesome pilot also. Great review. 2 thumbs up in my book.

Enjoying your videos of the GLADIUS MINI

Beautiful video and great review as always!

This is actually awesome. I think I’ll get one for myself

Very cool, I like the way the telemetry is laid out on the screen.

Very cool Dustin

Best Subnautica graphics I've ever seen!

Great review thanks. You gained another subscriber!!!

Wow. Thanks man. Never seen such a thing. It was cool. Great video.

Great review! The shots of the turtle sold me on getting one!!

Coolest freaking video! This is amazing! I really enjoyed this. Thanks Dustin!

use it to find all the lost Mavics ;-)

Great review. Thanks for sharing.

Ive been looking around for an underwater ROV and I wasn't impressed what Ive seen for the prices but this one looks great and awesome video....Thanks so much! AND I subscribed cause want to see more videos.....I live in canada and this is something I would use up here come summer...I also fly a Mavic 2 Zoom :)

Use the light to colour balance the image. The red spectrum from sun light is filled out through the first inches of water, that's why underwater footage looks blue. I hope this helps.

Beautiful! I can see it as adding some great advantages to fishing the Florida Keys! Until, Billy Bob and Mylo run over the cable with their prop! Thankz!

I think this is another great submarine. You have also great places for shooting great videos, reviews.

Beautiful video. What a fantasy.

Wow! Great review,. Maybe you could go through all the pros and cons of this model vs the others but I kinda of did it myself after watching this. Thx!

WOW nice toy :D Awesome video. Thanks! ☺

It is amazing underwater world!Thanks for sharing👍

thanks for a great video..I'm shopping for a sub..sold me on this one

Liked* even before the video started!

wow, this is awesome!!!! Very nice

very cool Dustin you get to have all the fun lol

That's far and away better than anything to date especially given the shallow water turbulence around the coral. And it's such a small package. This would be great for a boat club for inspecting moorings, boat hulls and just for fun.

great review, and looks a great sub !

Wow! I haven't tried my Gladius Mini yet but your reviews are reassuring that I made a wise purchase. I hope to get some Puget Sound footage and will share it, too. By the way, superb helpers are hard to find and are worth lots of ice cream. You're a lucky dad. Jess

Dustin! Loving your videos... I got a gladius mini for testing and a powerray from powervision! Thanks for your videos? Props from Portugal!

Thank you for this wonderful video! Love the turtle, so amazing to see. Sure you have Animal Planet, RU-vid and whatever.. but nothing this "private" and personal. Awesome video!!

Wow cool I've never seen anything like this before

Very cool i need one lol keep up the great work bro!!!

I love this! I bet off a boat can get some beautiful underwater footage

Kool and I just sit there and drink my beers

Great job ‼️

Man this was amazing

Great review Dustin but what I think would be great on that sub and other subs is a camera on the belly looking straight down. You could switch between the 2 cameras and even split screen

Amazing, and the turtle 🐢👍😊😊😊

Nice good test 👍👍👍👍

Very cool

That was brilliant. I want 1 😎

Nice underwater footage!

Bellissimo complimenti per la visione

I Love the machine!

Spirirt of egelege i am woowed this is awesome.

I am on the island of Crete Greece and I wish I had this sub drone man. Very cool

Awesome! Need get that kind and I have DJI phantom clone too.

Awesome video. And beautiful yellow trumpet fish at 44:50

Great Video, impressive drone

yeah thats beautiful 👍👏

Awesome video, well done, just subscribe

very cool bro

Awesome!!!

Is the FAA going to regulate this thing too? Never know, a plane could crash into the ocean and run into it... Scary shit!

Cool ROV. I operate commercial rovs offshore in the Gulf of Mexico. Cool to see a small one like this.

Hey Dustin.....I decided to buy the Gladius Mini with extra tether and the backpack.... Waiting on delivery now...cant wait...so pumped...Thanks for all the video you have done on the mini, they made me decide this purchase

Really nice footage, thought all coral was dead by now... Need to go to Hawaii soon

Hey keep making videos I love theam so much don’t stop or I’ll die

Is this a full time gig? Very cool under water shots . Might look into one of these this coming up summer off the pontoon boat 👍

'I've got precision control...', sub pitches like crazy lol. Just kidding great review!

Very Good!

That thing is cool!!!

Hi! Nice review! What can you recommend to buy today: this one or PowerRay (and why)?

I didn't know these things existed!

The cost is $1500. The clarity is top notch. I never saw stick movements on the controller so I'm assuming it's like a drone. I can see where this is a useful tool and a lot of fun for a hobby. Thanks for sharing Dustin!

Nice video! As a 15 year veteran with work class subs, I am impressed with this mini. I like the positive buoyant tether (especially when flying around all that coral), which is not possible on deepwater work class subs. The tether tug could be greatly reduced if there was a swivel or knuckle at the connection joint. A tether reel would be great, since you are introducing "turns" in your tether as you are paying it out. However, a tether reel would not be very cost effective in this price range because it would require a "slip ring" connection to prevent twisting of the tether when paying out and hauling in. But, I still want one!!! Thanks again for the video!

Nice vid

Must get one...

Great video thanks for sharing it. Make yourself a spool with a winding handle like a fishing reel and see how easy it is to wind the line in and pay it out with no problems. Trying to wind that line back on that stick is going to cause so many loops in the line. Happy Fish Finding lol

Very cool. You should have had mask, snorkel, and fins in case that tether got snagged. It would probably do better if it has side propulsion to prevent drifting.

That was cool.. little one was bord 😂😂😂 thank you 😊

Goals 🤙🏻

folding a half loop in the tether near the gladius with a small length of flexible rubber attached to each side may increase stability (need to be careful of snagging though).

i am loving the pitch and PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO ! PHOTO !

great Vid

Love it

Super cool... 👍

Hi Dustin, I’m on the Big Island and this video makes me want to give it a try. It looks like you’ve tested a few underwater drones, which one do you prefer?

Wow that's dope

Bro,definitely loving this one the best dustin, its kool how your kids help out with when you do your reviews while piloting crafts,so on amazon this is going for like 1600.00,but worth the money.

Amazing in cool

beautiful

8:18 this is awesome one day I hope to work with autonomous underwater drones (not saying that's what's in the video) I just like the underwater exploring/mapping aspect 20:20 wonder if they could apply those color correcting algos make the photo look more vibrant 21:53 damn that's a mouthful "humuhumunukunukuāpuaʻa" wonder if it has dynamic ballast, I imagine much quieter than thrusters

That's so beautiful. But you live in Hawaii. I don't think I would have the same experience in So Cal oceans.

Good review, nice to see when it's a bit of a current. Seems the longer the tether the bigger risk of it pulling? Only logical. The weight of the cable in relation to the weight of the ROV. They are sending you these for review right? You're not buying them?

Very nice review. I'm glade to have find your chanel. By the way, a fishing net would help you to grab the sub from a rocky "beach" like that, no?
