When it comes to marine electronics for fishing, you have a wide array of choices. In addition, you can also get an iPhone software called FishHead that tracks weather, tides, and even lunar information! But for most people, fishing electronics usually brings to mind fish finders and GPS systems. They can be purchased separately, or in combo units saving mounting space and money.

There are several things that should be considered when deciding on fishing boat electronics.

When it comes to transducers on fishing electronics, there are single frequency transducers and dual frequency transducers. Single frequency transducers are used for lakes and shallow coastal fishing, while dual frequency is used for deeper water fishing. In deep water, the higher frequency transducer on a dual transducer fish finder is the one that shows you the fish.

You can also get display screens on marine electronics with many different resolutions. Indeed, higher resolution, brings better image. Color screens can be better viewed in direct sunlight. The overall size of the display may be anywhere from four to seven inches, measured on the diagonal. Generally speaking, the more power your fishing electronics come with, the better the results, even in still or shallow water. Depth penetration is related to the power and quality of the transducer. Better transducers penetrate the water best. Saltwater and muddy water will limit the depth to which your fish finder will penetrate.

Norcross makes a portable fish finder with many new marine electronics features including several sensitivity settings and a mountable and side scanable sonar sensor. To use it, you need to power it on, toss the floating sonar sensor overboard and get instant fish, depth, weed, and contour readings on the handheld monitor device. It updates depth readings four times per second for high accuracy, and you can have the information displayed in meters or feet. The LCD monitor blocks glare with Polarized VirtuView technology and SoftGlow backlighting. It has an audible fish alarm and enables accurate measures of weed height.

Eagle makes a line of inexpensive to mid-range fishing electronics that are boat mounted. Some of them have grayscale screens, and some are color. The color screens are easier to read in bright sunlight. Those fish finders start at as low as USD 100.

Humminbird is also a popular line for marine electronics. Though they, too make inexpensive fish finders, they also have some more gadgety models, too, such as a combination wristwatch / fish finder, and specialized fish finders for ice fishing.

Lowrance is considered one of the higher end providers of marine electronics, including fish finders. They include bigger screens and better resolution than the more basic brands, though they, too, have a couple of more affordable models, and one model that is specially designed for ice fishing.

Marine electronics for fishing include fish finders and other devices that combine multiple features. You can buy a fish finder for 100 dollars and you can pay several hundred, too. Your specific needs and budget will determine which type of equipment for fishing will best suit your needs.

How To Detect And Prevent Air Leaks In Your Home

by

Roberto Bell

If your house has air leaks, your electric or gas bill is going to reflect it pretty quickly. So how do you detect whether you have air leaks in your home and what do you do to prevent them?

A heated house is much like a chimney in that they both hold warm air and are surrounded by cold air. In this, a house will draw air in at the bottom and expel it at the top. All winter, a heated house is trying to push air through the top-floor ceiling into the attic. But when looking for air leaks, in addition to looking in the attic, you want to examine your whole house. Air can leave the house at any point, seeping out your precious warm air and letting in cool air.So what is the rule of thumb when looking for air leaks? To start, look any place that you may have what is called penetrations or discontinuities. Discontinuities could be where different materials meet, such as between brick and wood siding, between foundation and walls, and between the chimney and siding. Penetrations are places in your home where holes have been drilled for exhaust fans, ducts, chimneys etc. Look for small holes such as those created for electrical wiring and cable installations as well.Also look for bypasses, which are major air passages from any floor into the attic. Dropped ceilings in the room below will often conceal a direct connection to the attic. Concrete-block party walls between row houses also often move house air into the attic.To look for air leaks in the attic, go up in your attic at night and see if you can see any light shining through from the floor below. If your home is older, the most thorough way to prevent air leaks in an attic floor is to seal all areas where pipes, ducts, or wiring pass through the floor. Leaks can be sealed with caulking, expanding foam, plastic, or other methods.Another common area to examine for air leaks is around windows and doors. Starting with your windows, use a waterproof caulk and a caulking gun or simple weather stripping to seal any air leaks you may detect around a window’s frame or sill. Replace older windows with ones that offer greater protection from air leaks. Windows marked with the government’s Energy Star designation are ideal for insulating your home. The durable materials used in Energy Star window frames provide greater protection against air leaks.As for your doors, seal drafts that occur around exterior doors. Exterior doors contribute greatly to the problem of air leaks. To help stop drafts you can install a doorsill, weather stripping or a door sweep. Weather stripping or foam insulation strips can be purchased at your local hardware store and is available in varying thicknesses. Choose the thickness based on factors such as how tightly your door closes. If you can look at your door during the day and see light, you may want to use a thicker strip. If your door closes tightly, choose a thinner strip. You can place the strip on the areas where you feel heat loss. Typically on a door, placing the foam insulation strip along the inside of the door jam makes for a neater appearance and less people tend to notice it.Some of the less obvious places to check for air leaks is electrical outlets and light switches. Sometimes you can place your hand over these areas and see if you can feel a breeze. It is more common to have an air leak at the exterior walls, but depending on how your home was built you may have air leaks at the interior walls as well. Electrical outlet and light switch insulators are a great place air likes to come in. Check these as well.Next, if your home has plumbing coming in directly from under the house, these areas can be left unsealed. Look under the sink for any holes around the plumbing pipes. Foam insulation can be placed around the pipe to seal small gaps. For larger gaps consider stuffing the holes with steel wool and taping over it with duct tape. This will not only seal the air leak but also prevent mice and rats from chewing through to the inside of your home. If your plumbing pipe has a cap around it, pull the cap away from the wall. If there is a hole, simply use the foam insulation strip to fill in the hole by wrapping a small strip around the pipe.If you cannot seem to figure out where your house is leaking air, an infrared scan can be used. A professional can examine your house with this heat-sensitive camera and then be able to provide you with where there is at least 10 C difference in temperature between inside and outside air.If you are on a tight budget, consider closing off rooms that you do not commonly use. Close off air vents in the room and keep the door to that room closed. Place a towel at the bottom of the outside of the door to prevent the cold air from getting to the rest of the house. This works really well and helps to save money on the heating and air bills.When you seal up your home, you will notice pretty quickly a difference in your energy bill and possibly find yourself a lot more comfortable during the harsh winter and summer months.
