Conventional vs. Bait Casting Reel-What’s the Difference
In many ways, bait casting and conventional reels are a lot alike, but what differences exist determine how anglers make use of them in saltwater and fresh. Although they are both worlds apart from spinners, bait casting and conventional reels are nearly alike with each other. Is it possible for a greenhorn fisherman to tell the difference? Although some reels could be used for either use, non-spinners are actually meant fishing from a boat (vertically) or the shore (cast).
Before we discuss differences let’s talk about similarities. The axis on the spool on both types of reels is perpendicular to the rod and they spin when you cast or let out your line. They are aligned in this manner to allow smooth casting. If you’ve looked at spinning reels, you’ll find they are parallel to the rod – holding the line in place until cast.
Each also offers a crank handle, which is found on the reel’s side, and lefties or right-handed anglers can use them. A level-wind feature is present on each as well, offering a guide that moves forward and back across the spool. As you release or reel the line, it winds the line evenly, rather than allowing it to pile on one side or the other unevenly.
Now, bait casters are built to maintain their best performance, meaning smooth release of the line and a safety against every fisherman’s nightmare—backlash. Most manufacturers use magnets or even centrifugal brakes to help avoid this backlash. Backlash is a common problem, happening when the lure/bait hits the water, stopping suddenly. However, the spool is still spinning, and it quickly winds itself back over its spool. Most fishermen hate this “bird’s nest” effect, but novices see it often. These reels (meant for saltwater) usually include such models as Saltiga’s Surf, Abu Garcia’s C3, the SX by AVET, and Shimano’s Calcutta, among others.
The Charter Special (Shimano), Sealine (Daiwa), and, the friend of every fisherman, the 114 and/or 113 by Penn are conventional reels. These are often better suited to dragging fish in. these reels boast in-line alignment which helps ensure that while you’re reeling in the catch of the day, you’re not placing undue stress on your valuable fishing gear. Most fishermen feel that these reels are less work and far more comfortable. They also have the added benefit of being ideal for trolling, three-ways and also for jigs.
There are surely a wide variety of reels on the market, so of the other popular Penn Reels include: Penn 975 and Penn 209.
What type of centrifugal pump has low resistance?
i need a pump that has low resistance and able to pump water up to at least 0.5m. It is powered by a wind turbine mechanically. I am going to use gears to increase the revolution of the pump. The gears may have some resistance, so i was hoping to get a pump with low resistance to prevent further power loss.
Sounds like what you need isn't a centrifugal pump, but an axial flow pump, if the head is only 0.5 m and you want high efficiency. However, you could have trouble finding such a pump in your local hardware store, unless you're out in farm country. Farmers like using axial flow pumps because of their efficiency at high flow rates, and they (farmers) don't need much head.
Edit: Let's use the analogy of air blowers. The ones that blow the most air using the smallest direct-drive motors are propeller type fans. It's the same reason why wind turbines are mostly prop-driven. If your head is low (only 0.5m), then a propeller-in-a-tube (that's an axial flow pump) is the easiest way to move water at high flow rates, without requiring high rpms. Centrifugal water pumps, on the other hand, require higher rpms for greater efficiency.
Pump technology review: There is a continuous morphology in rotating pump design starting with the simplest propeller-in-a-tube design all the way to multi-staged centrifugal pumps, going from minimal heads all the way to very high heads. You generally want to match your required head with the right pump for maximum efficiency, if your intention is "to prevent further power loss".
