When you’re out fishing, you need to know several things, all of which can now be supplied electronically. For example, your first need would be to have weather warnings so that you’re not in any danger. Devices can be installed that show you up-dated weather patterns and help you navigate around the worst of a storm and can get you safely home. Then there’s the issue of actually finding fish, and this can now also be assisted through various devices that use sonar waves to send images of what is under your boat. These images can be sharper or less distinct depending on the sophistication of the product you buy.
The fish-finder devices can also provide information of how deep the water is that you’re in, as is the case with Garmin depth finders. This assists in areas where your boat has a certain draught and the device can steer you away from shallower waters, but also lets you head for deeper waters if this is where the fish you’re searching for can be found. More sophisticated depth-finder devices actually allow you to make your own maps based on the data that you have received – these you can store for future use if you’ve found a particularly good fishing ground, or can be shared with the rest of the fishing community.
Deciding to purchase a Garmin depth-finder
As with any other purchase, before you buy you need to establish clearly what the purpose of the investment is based on your needs. There are a variety of different devices – some can be individually purchased, while others combine many different features into one device. An important consideration is a power, and you need to look at the required wattage for each device. It stands to reason that if you need rapid readings you will need more wattage, while a lesser powered device will give you slower readings. For those who need immediate information as to what is underwater, the faster the feedback, the more accurate you will be as to where to position your boat. With a depth-finder, you will also require extra wattage if you need the sonar waves to travel more deeply. With a lower wattage you can probably still receive deeper images, but they will become increasingly fuzzy and hard to interpret accurately.
Then you need to consider the amount of pixels that you will need on your screen display. As with any other screen, the higher the number of pixels, the more detailed the image you will see. High-resolution screens are most efficient for a sharp image, and would probably be worth the extra investment. Again, if you purchase a slightly bigger screen you will have a clearer picture and will be more easily able to differentiate between the images and data that are displayed.
