BPS-4 4-Transducer Ultrasonic Antifouling System - 12VDC
The BPS-4 is a four-transducer system that can add antifouling protection to hulls, drives, rudders, stabilizers, and more. This single system can provide ultrasonic antifouling protection for hulls up to 50ft in length or can be combined with additional systems for larger vessels. The BPS-4 can also be tasked with protecting drives and rudders.
The BPS-4 Package Includes:
- 1x BPS-4 Control Module with Integrated Power Cable
- 4x Submersible Ultrasonic Transducers with 15ft of Cable
- 2x Additional 15ft Extension Cables
- 1x Epoxy Kit
- 1x Printed Installation and Operation Manual
Specifications:
- Voltage: 12V or 24V DC
- Average Power Draw: 1Ah
- Transducer Strength: 60W
- Cable Length: 15ft per transducer
- Frequency: Multi-frequency ultrasonic sweep algorithm (20kHz-42kHz)
Installation Overview:
- No Thru-Hulls: The transducers are installed directly on top of your hull surface using the provided epoxy.
- Install Signal Cable: Each transducer has 15ft of connected signal cable. This ensures an easy installation from the transducer to the controller.
- Mounting the Controller: The BPS-1 Controller runs off of your boat's existing house battery. It is a simple 2-wire connection the the battery bank or distribution panel.
- Enjoy Worry-Free Boating: That's it! Your BPS system is done! Let our advanced antifouling protection do its job. Each system is programmed with a multi-frequency sweeping algorithm to ensure that your boat has the best antifouling protection on the market.
How the Technology Works:
- The Mechanism: The system emits high-frequency ultrasonic waves through the hull & drives, creating a microscopic barrier of resonance.
- Targeting the Root Cause: These ultrasound waves repel biofouling from attaching to your hull before they ever have the chance to attach.
- Eco-Friendly: 100% chemical-free. It does not leach pollutants into the water, making it safe for marinas with strict environmental regulations.
- Marine Life Safe: The frequencies used are outside the hearing range of marine mammals and humans.
Benefits:
- Fuel Efficiency: A clean hull creates less drag. Maintaining hull smoothness ensures you get the best possible MPG and top speed.
- Reduced Maintenance Costs: Significantly extends the life of your bottom paint and reduces the frequency of expensive haul-outs.
- Diver Savings: Reduces the need for monthly hull cleaning services.
- Hard-to-Reach Protection: Unlike paint, ultrasonic waves resonate through complex parts that are difficult to paint and clean, such as stern drives, sea strainers, and rudders.
- Fit & Forget: Once installed, the system runs automatically with zero scheduled maintenance required.

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles.
Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need.
The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup.
Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room.
The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams.
The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money.
What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.
