Fishing is a leisure activity which is enjoyed by numerous people. They go on trips with their family and friends on a Sunday afternoon, and sit quietly alongside the water to catch one fish at least. Meanwhile, fishing is an occupation too. It contributes a large amount to the employment sector of this world. The people who fish are known as “fishers”. They fish and sell the fishes in the market. It requires a lot of patience, whether fishing is being done for leisure or as a job. Sometimes it’s very easy to catch fishes while sometimes it is very difficult. We don’t find fishes. That’s how “fish finders” came into market.
A fish finder, also called sounder, is an instrument used to locate fish in the water. It detects by reflected pulses of sound energy. It uses the technology of sonar. Today, the most famous and popular device is- Garmin striker 4.
Garmin Striker 4 review features:
- It has a 3.5” screen
- 480H x 320V pixel resolution
- HVGA colour
- Dual frequency CHIRP
- Depth capability of 1,600 ft (487 m) in freshwater and 750 ft (228 m) in salty water
- 220 W transmit power
- Has a GPS of high precision
- Waypoints- 5,000
- Transducer is of 77/220 Hz
- Has a 4 pin connector
Its dual frequency CHIRP sonar adds up a little power and clarification to the images displayed on the screen. It provides better defined targets, less cutters and a much better lock to the bottom. CHIRP is best for target separation. Normally, when two fishes are very close to each other the fish finder’s conventional sonar unit their sonar and shows them as one bigger targeted fish. But this confusion is controlled by this sonar through the frequency technique it uses. You can see all the targets separately as they are below the water.
It also has a fish symbol ID whose function is to analyze the sonar that returns differently and to assign icons for the fish. It also shows the depth of each target. The flasher mode available helps it all. It is a circular depth scale incorporating information about the sonar beams coming from the targets. The strength of returned sonar is detected by the outer rings of flasher and depth is detected by the inner rings. It is also known as the “A-scope function”.
The navigation system in Garmin Striker 4 does not feature a chart plotter. However, there is an internal GPS module available.
Its cost ranges from $170 – $120.
So overall, the pros and cons of this product is listed as below-
- CHIRP 2D sonar
- Dual frequency
- GPS speed
- Saves up to 5,000 waypoints
- Installation is easy
- Multiple sonar feature a like A-scope, Ultra scroll, fish symbols, flasher etc.
- No NMEA connectivity
- Unit cover is not included
- Longitudinal and latitudinal information is not available
So if you want an option which is cheaper and has a good sonar feature, this Garmin Striker 4 review is a must for fishers.
