Buying Guides

1. Standalone, combo or network powered depth finders

There are three types of depth finders for you to choose from which are the standalone depth finders, the combo depth finders and the networked depth finders. Each of the three types features different or combination of methodologies in finding fish and these differences are below: 

  • Standalone fishfinder: This type of depth finders gives you the biggest display for the most affordable cost. Therefore, if you only run a small boat, or you’re on a limited budget, this type of fish finder is for you. Otherwise, you should buy a bigger depth finder with a bigger display or two bigger displays, which would make you a professional.

  • Combination fishfinder/chartplotter: For mid-sized boats with the integration of GPS navigation for fishing. Using GPS for navigation to the fishing grounds, viewing both on splitted screen, or viewing only the depth finder would all be cool with this type. Note that this type can be upgraded from the standalone type if you want to do some tweaks or engineering.

  • Networked system: With this type of depth finder system, we have information from all types of data sources including radar, vector GPS charts, raster, video, and satellite radio. Some depth finders are also equipped with Bluetooth/WiFi, for you can control the device from your iPhone or Android smartphones. Your depth finder, often an external “black box” module, is just one of these sources of data. This type is the most advanced type of depth finder system; therefore, it would cost you the most.

2. The type of engine

There are two styles of depth finders, which are the style that uses the CHIRP (Compressed High Intensity Radar Pulse) and the type that uses broadband depth finders. 

  • CHIRP finders: CHIRP finders sweep the frequencies in a range, for example 130 - 210 kHz, instead of transmitting an individual or a combination of two or three frequencies. CHIRP fishfinders transmit less power than a traditional fishfinder, but their wide-band, frequency modulated pulses can be very long in duration and put 10-50 times more energy into the water. 

  • Broadband: It can be less flexible than the CHIRP finders, but it is the traditional type and uses less power than the newest modern CHIRP engine.

3. The size of the screen

The screen is responsible for showing what’s going on underwater. Therefore, the screen or the display should be wide enough for you to see all the possible details. 

A depth finder’s screen is often bigger than your phone’s screen and smaller than a tablet screen. They’re usually made of the LCD technology, and the LCD is described below:

The LCD technology: LCD stands for Liquid Crystal Display. An LCD display consists of two parts: the backlight shines a pure white light source to the world, and the panels block some of the light’s parts to produce the required color. LCD panels are cheap, durable, and produce stunning contrast ratio.

4. The wattage

Depth finders often run on battery, so you can expect to waste the energy on the depth finders. These are the most common wattage ranges for the best depth finders:

  • 200W or below: Suitable for in lake depth finders for fishermen. This type of depth finder is weak and only capable of sweeping for a small area. Therefore, it would not work in deep sea water or in the ocean.

  • 500W: This is the most popular range of wattage. It doesn’t consume tons of power and still provides the users with what they need. This is enough for your coastal fishing.

  • 1000W or more: The most powerful depth finders you can find on the market. With this range of power, there’s pretty much nothing to worry about when going out for fishing, scanning or anything you can think of.


FAQs

1. How is a depth finder useful?

A depth finder points out what’s under the water or outside the coast. A fisherman can use a depth finder to determine what they should expect when going on fishing outside the sea. 

Not only does the depth finders provide information about where and how fishermen can get fish but they also help protect the users from the dangerous things such as sharks or whales.

2. My depth finder doesn’t work, what should I do?

If your depth finder doesn’t work, the procedure for your should be as below:

  • Turn off your depth finder to avoid any circuit damage

  • Check if there’s any water that’s gotten inside your device

  • Try to restart the device and check if it works again

  • Adjust the antenna and the transducers to see if you get any signal

  • Finally, if all of the above don’t work for you, take it to the professional repair store.

3. Can I replace parts of my depth finders?

No, you should never do that. A depth finder is an advanced scientific device equipped with sophisticated features and electronic components inside. Unless you know exactly what you are doing, you SHOULD NOT take your device apart because you could break your device and simultaneously lose your warranty.

4. Is my depth finder waterproof?

Most of the time, yes. Brands know that everyone uses the depth finders in the ocean, or the lakes. Therefore, they would be likely to make the device waterproof. 

To conclude, you should double check with the specifications about the waterproof or water resistant capabilities. However, if you forget, you can be 80% sure that the device can somehow withstand a specific amount of water

5. What about the warranty of my device?

The depth finders usually come with one year of warranty. In our personal experience, you have to really care about this warranty period, because depth finders are an important type of equipment on your sea trip, and they’re expensive to replace. 

Be sure to check all the related information with the depth finders’ warranty before purchasing one.
