I just watched this and you explained very well..I will see if I can buy a pump like you use with 160 -180 out put..adding a good air filter at end of regulator hose seems great...just not sure what filter,type etc to buy..also is the clear hose 3/8 inside diameter? Thanks
I don’t remember at the moment if it was 3/8 ID. It would depend on what barb fitting you add to the pump. Definitely 160-180 pump. A basic inline air filter should do the job. Thanks again for watching
@@us_angler1845 I went with 3/8 inside diameter..do you have any idea of your psi to your reg...I ordered cheap reg,but I hear they can be adjusted..I am thinking around 60 psi to reg 10 to 15 feet should be good...th as thanks
Hello great clean video. May I ask how many AH is that little battery i know its 12v and your said it last about 2hr. But just so I know the battery is 12v / ? AH
Hello thanks for watching. I do believe there is a way to add a pressure switch to the pump. I think it would also require some type of air reservoir. Just the amount of air in the line would not be enough for the pump to build pressure and shut off. I’m going to rebuild the unit this winter using some of the suggestions. Thanks again for watching

I can’t find a 180 at the moment. If I can find a link for a 180 I’ll send you the link. Thanks for watching
I see all the guys who make these do the same fatal design mistake. Please don’t do this design because it will kill you if you don’t plumb fresh air directly to your air pump. All these same design makes you breath the same air the battery is in . So if it off gases you get a chemical mix of whatever batteries you are using and then you breath the fumes. 😤
Thanks for watching. I do appreciate the comment. I’m in the process of building a new safer system. It will include a fresh air snorkel and battery/ pump divider. Thanks again for watching
Thanks for watching much appreciated. I’m certified in scuba. This system is definitely cheap and not a scuba replacement. We built this for shallow treasure hunting and cleaning the bottom of our boat. Thanks for the input
Ive done some preliminary testing with this pump and honestly i would just use two of them WITH an activated charcoal filter at the very least. Also, i feel as though any video talking about DIY underwater breathing should emphasize the enormous risk of lung over-expansion, because a lot of people building these things have never recieved any scuba training.
Hello thanks for watching and for the feedback. I definitely agree with you the pump I bought is small. I would definitely go with probably a 180lpm if I built it again. This system is definitely only for shallow water use. I don’t remember what topics I touched on but I do believe I mentioned safety and risk. Definitely appreciate the comment and feedback.
Thanks for the input. I have an update version with added safety features. I’m just about done testing. The video will be uploaded in the next week or two. Thanks again for watching
Thanks for watching. I have not had any issues with the heat for the pump. I’m normally only running about 2 hours at a time max. The air is fine. I was thinking about adding a plexi divider between the batteries and pump. Then running a snorkel into the pump chamber. As of now it has not been a necessary improvement. Thanks again for watching
Thanks for watching. It’s pulling air directly from the surrounding air so it’s basically breathing greasy air. It’s oil free and just a diaphragm system. The one thing I would possibly change would be to section off the batteries from the air pump and put a raised intake on the system. This is the same style pump used in the air buddy so I’m very comfortable using it for diving. Thanks for watching
If you know what you are doing and do it safely yes it will get you down to 30 ft. If I was building it again I would step up to a 160 or 180 L/M. The 120 I have is enough to go 30ft but you can’t really exert to much energy or you will get gased. It’s just enough to keep up and allow you to still intake air with the added pressure
Really brilliant I'm Italian I did not understand how long in your opinion it can be used under water with this battery, how can you then charge it? with a normal car charger?
Hello thanks for watching. Mine will last around 2 hours on a single battery and longer if I add a second battery into the box. The batteries I’m using at small power wheels/ lawnmower batteries. Once they are low you will have to just hook it up to a regular 12v battery charger. Hope this was helping. Thanks again for watching
Thanks for watching. I do plan on adding an inline res at some point. I like the added air capacity and I definitely agree with everything you have brought up. It just has not been done yet. I’m thinking about making a PVC float around the box out of like 3” or 4” and that will be my air chamber. The pump will feed into the pipe and I’ll have an outlet of the opposite side. Thanks again for the suggestion.
Are professional pumps certified in some way that the air is 100% clean and not harmful. Please be careful with your child breathing from that pump. Why not buy any low cost pump from Harbor Freight then and using it for this purpose? How does an inline filter get out all the potential harmful things from entering your body? Not saying this is not a good idea just asking logical questions.
You are not wrong. The air buddy and similar hookah systems all operate the same way. An inline filter definitely helps. The pump I’m using is a diaphragm pump so I feel much better using it compared to an oil style air pump. Thanks again for watching.
Thanks for watching. At the moment I don’t have anything set up. I imagine it would be beneficial but I have not had any issues with air quality yet. Thanks for the suggestion I’ll definitely look into it.
@@us_angler1845 I think the issue is that the air may seem ok but there could be the odd tiny particle of metal from the pump which you wouldn’t know about. (Like asbestos) You need a filter dude, ideally quite a good one.
Hello thanks for watching. That is definitely an option. I didn’t lose much in length by running it out the top. I’m in the process of building a better safer system. The video should be posted soon. Thanks again for the view and comment.
Hello, I have a scuba gear that I made myself, but it is a bit heavy. I liked your project, could you tell me what volume of air your compressor delivers? And what depth can you reach with it. Thanks!
Hello thanks for watching. The pump I’m using is a 120lpm. If I was to build it again I would definitely use a 160 or 180lpm pump. I currently have 20’ of hose and I’m more than comfortable going 20’ deep. All that being said if you use a bigger pump it will reduce battery life. Also I would like to add a small floating air bladder just for safety reasons. Should the pump die or something happens that extra few breaths would definitely help. I am scuba certified but this is in now way an approved system. Build at your own risk. Thank again for watching
@@us_angler1845 Okay, thanks for the info. I will use the equipment at depths of a maximum of 4 meters. This ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-W-0XIwsy4Os.html ) is the equipment I built 6 years ago, it's good but very heavy! Thanks!
You should have at least 2 inline air filters too. I built mine with the 180 pump. And I added a air chamber that will allow at least 2 breaths if the pump dies.
Thanks for watching. I appreciate the input. I plan on doing a chamber for sure. I never considered a filter but it’s a good idea. Thanks again for watching
I was able to find same pump in your ebay link,but a 160 l per min at 120 watts..its $20 more,but should work great...of course if I used same battery as you run time would be cut in half,but 30 mins should be fine...I may add a little exhaust fan to box to keep temps a bit lower also..
@@us_angler1845 I ordered parts last night,even went with same battery you used..what I like about this is when battery gets low you will notice air production is weaker and call it quits...also I am sure you will also hear motor,so if it kicks off and you are 10 foot deep you can surface safely..they make a nice inflatable cooler float for $10 WHICH should be great to hold battery box...i did order 50 ft of 3/8 clear tubing..will cut it down to 20 ft..Did you ever have air seem hot when breathing? Will be trying to figure out filters..not sure its necessary,these motors design should deliver clean air..thanks again
ThNk you for this video. I’m getting into spear fishing but not planning to go any deeper then 10ft. I think this diy video will help me on my lungs while hunting for fish. Thx again
Thanks for watching. It’s definitely a fun little project and can be used so many different ways. I’m glad you enjoyed the video. Thanks again for watching
Hello thanks for watching. I personally have been to 20’. The working pressure is ok. We don’t ever go much past 15’ just as a safety measure. I have heard of people going 30’ on similar setups. I’m in the process of a redesign with an onboard are pressure tank for additional safety. Thanks for the comment.
@@us_angler1845 What do you plan to use as your onboard pressure tank? I plan to use mine in the sea to a max depth of 30'. I purchased the 160 LPM version. I couldn't find anything with a greater airflow.
Engineers could easily build an ar glasses receiver to a mini arm PC at the top making sure everything is okay and give you alerts if there's a problem.
Thanks for watching. Definitely an interesting idea. I don’t think I’m going to attempt to build that for my system. I do want to put a reserve tank inline. You can usually hear the pump running above you. Should it kick off the reserve would definitely give piece of mind. Thanks again for watching
Hello thanks for watching. I’m not 100 percent sure but I believe a pressure switch could be add. The way this is set up there is no tank for air. It’s a direct feed from the pump to the regulator. I have thought about adding a 3” pvc tube as an air chamber. That would give the ability to add a pressure switch. Appreciate the comment thanks again
@@us_angler1845 so how long have you ran pump at one time? Ever try it at a depth of 10 feet or more...? The key is finding a great motor.the rest seems pretty simple...thanks
What do you think using a compressor with small tank? So it would only run once tank is low, perhaps could be more efficient on the motor? Thanks for sharing your video btw
Hello thanks for watching. I have thought about switching over to a different pump with a tank and pressure regulator on/off. The only thing I see if you lose some of the compactness of the system. I have not looked into a 12v compressor that will do that. It’s definitely a good idea. I may experiment with the system this winter. Thanks again for watching.
Thanks for watching and the comment. It’s definitely a shallow water rig. I’m a certified diver and can run down to 30 feet with it but my comfort zone is anything 15 feet or less. I have never had it die or stop working while underwater but it a possible for sure. Hope you like the video thanks again
I would probably use this as a inline filter. PCP Hand Pump Air Filter, Water-Oil Sparator with 8mm Female and Male Quick Connect for High Pressure Air Compressor Pump 30Mpa (Blue) a.co/d/7opoirl As far as a tank www.pioneermining.com/cart/index.php?route=product/product&product_id=311 this is what I would use. Just an inline plastic reserve air tank. Thanks for watching
On average about a hour per battery is what it get. I will say using led acid batteries. They do degrade because my son likes to run them completely dead. It’s hard on the battery to drop that low and be recharged multiple times.
@@us_angler1845 greetings from medellin colombia a hug, the chinese pump has dangerous metal residues, it does not meet the quality, many like me disarmed it and cleaned all this leftover material inside and changed higher quality parts
I’m getting 1 to 2 hours depending on how hard I’m working and how heavy I’m breathing. If you bump up to a larger pump that will drop a bit I imagine. Thanks for watching
Hello thanks for watching. I have not upgraded my pump. The system is working for me as is. If I was going to build another one I would definitely get a larger pump. Thanks again for watching
@@theartist8189 yes just make sure its a sealed one, and that it cant get wet... lithium can explode if it contacts water.. keep that in mind when designing your system. It needs to be water tight, and a sealed battery
The pump is 120lpm if I was going to do it again I would use 160 or 180lpm. I have been down 7 meters with it and it’s ok but not great. We stay average of 5 meters. Thanks for watching.
@@us_angler1845 Obrigado pela dica amigo ! estou querendo comprar um de 25 l por minuto e queria mergulhar a uns 3,5 metros de profundidade, porém estava na dúvida se ele iria me atender .
Hello thanks for watching. I have not had any issues with this pump overheating. I have not run it for more than 4 hours in a single day. I can only speak for my experience so far. Thanks again
@@us_angler1845 and do you think that 2 120 lpm pumps would work better than 1 160 lpm as far as letting you breathe easy at 30 feet under? Probably a stupid question... but i figured I'd ask anyway
Thanks for watching. I’m guessing you don’t like the system by the dead dead dead. It works really well. Very similar to an air buddy and a few other products. It’s definitely not intended for deep water. More of a swimming hole searching device or used to dive a boat and check it while in the water. Thanks again for watching.
@@us_angler1845 super dangerous , that is not the correct way to build it. do more research on these before you show people how to build such a dangerous build.
I am using 120v pump from harbor freight 135 psi. around 60 lpm regulated at 90 psi. why do you think your system requires so many lpm. I am by no means starved for oxygen working moderate level scraping off running gear. just trying to understand because I want to go mobile with battery operated system. what pressure is your pump running.
Hello thanks for watching the video. This pump is only .12MPa. That comes out to around 17psi. Your system has 95psi behind the regulator so you continuous breathing is more than compensated. The 17psi the 12v pump puts out is enough to keep up but it’s not exactly ideal. Even bumping up to a 160lmp you are still only 17psi. Thanks again for watching
I made a float with high pressure 150mm PVC pipe and used it as a supply tank. Works great! Hope you gave your kid some lessons first, like never hold your breath and breathe out when ascending!
Hello thanks for watching. I have been thinking about adding a tank. Are you using a similar pump as me. I’m not sure if the pump I have will build very much pressure. I’m scuba certified and did make sure to give my son instructions. He is limited to the pool for now. We are going to get him certified soon. Thanks again for watching
Thanks for watching. The way it’s currently set up it a constant pump. The regulator dose hold some pressure. The pump itself is only pushing about 17psi so about the best add-on for my system would be an in-line air bladder/ reservoir. Thanks again for watching
Hello, you and I seem to think the same way, I also placed the compressor and the battery in the toolbox, instead of an inflatable raft, I used a penoplex raft. Are you planning to install a receiver?
Unsure what you mean by receiver. If you are referring to an air chuck then yes. I want to be able to inflate my tube when I get on location and be able to deflate for storage and transport
Hello I understand now. My friend is building a system that incorporates an air bladder inline. I have thought about adding one to my system for added safety and more comfortable air usage with the smaller pump
@@Archi-u8t There is a video on youtube wherein the hookah builder used very large diameter PVC plumbing pipe around the perimeter of the box as an air tank and a float to float the box, clever setup.
