Used it once so far, worked well.

The media could not be loaded.  To start, there are no real reviews on this product, not sure why. But My experience order this on Dec 18th 23 received delivered Dec 26th due to holidays. When I received the package it looked like it had been retaped. Upon opening it, there was a new hose in a slightly tore package was ok, there was charcoal in the filter(not sure if it was supposed to ship prepacked). replacement white filters were in the box, but there was no extra Charcoal to replace it, was missing. The regulator was attached to the filter and the coiled hose. Not sure if the Regulator was new or used, it had some slight residue on it. Now the unit itself, as you can see in the pictures it has what looks like white raised spots that look like corrosion maybe this was a Used Return main unit, with a new replacement hose, not quite sure but the plastic was off of the battery display screen. Now for the performance.. I'm 5'11 230 lbs. I was only able to use this unit a few times in 10-12ft of water. During those times I would just be hanging out with the reef fish, it was enough air flow for that. The unit would kick on after almost every breath, and sometimes run constantly. It was ok for shallow diving where you don't want to be snorkeling, and want to stay down. Today I finally was able to use it out on the main reef about 22-28ft total depth( this is my last day to return it, and hadn't been able to get out that deep) the wave were about 2 -3 ft at times. The unit ran constantly, I did have to noticeably take slightly harder breaths at around 20- 23 ft, and take slower breaths for the unit to keep up. The unit did well in the wave, I didn't have any water entering the intake tube that I noticed. I do not know the battery life as I've only used it maybe around 30-45 minutes before recharging it, at shallow depth. I'm not sure if this is a keeper. I don't plan on every using this more than 25 ft. However I feel if there was any kind of current you would have to kick in this my be under powered in that situation. I did purchase the Amzn 2 year warranty, if that is any good. 1 other thing this thing comes with a crappy tiny dive flag that just slides down the short intake hose and doesn't even stay up. I did modify the intake snorkel to accept a dive flag. This needs to have a real dive flag holder. Anyway, it worked well in shallower water, it didn't tip in 2-3 ft seas. It's nice and portable, not sure of run time, not sure of durability. Wish the pro wasn't so much, maybe they can send me a higher volume pump assembly if I keep this one? Any way hope this helps. Happy Diving!

Picked this system up for the 4.5 hours of run time. Hooked up a pressure gauge and it kicks itself off at 50 psi and back in again around 35 psi. Took it out today for 2 hours and still had 3/4 of a battery left on the meter. Definitely impressive and well built. Really like the new hose design. Also caught it on sale for $599.

Does exactly what it states.

I own the Aquarobo 510-3.5h and the Aquarobo 819-8Pro models.These are two aquarobo's that use different waters.The 510 is what I have for my kids and friends. They are not that used to diving so I use the 510 to let them try to look the underwater world, using the 510's solo, with plenty of air supply, enough for my family to play in shallow water, it's a great experience.I am a diver and underwater exploration player and I have been to many lakes and shallow waters. There are a lot of interesting sights to see underwater. I use the aquarobo 819-8HPRO model, the 819 model has a 117L per second air supply which is very large and allows plenty of time, 8 hours which is crazy.I would recommend the aquarobo brand to anyone who likes to dive or wants to try diving as it really does lead the way in this industry. Whether it's the valve technology or the air supply structure, the cooling system, the intake mechanism, it really is the best I've seen.Recommended.From Diver
