The Buying Guide
To narrow down your search, there are several factors which you need to focus on.
The first aspect is the frequency, and this varies with the depth of the water in which you would be fishing. For shallow waters, a frequency of 200 kHz would do, while in deeper waters, 50kHz would be ideal.
This is an essential determinant of your user experience. Therefore, we advise that you go for a device with a bigger and colored screen for clearer images.
Additionally, it should be backlit for easier viewing in the dark or under direct sunlight.
A high-quality transducer should capture the Sonar wave signals more easily and, therefore, boost your numbers even higher.
When it comes to water resistance, always check out the IPX ratings.
An IPX 4 rating means safety from splashing water, while IPX 6 implies decent resistance against high pressure water jets.
IPX 7 can stay up to 10ft deep for 30 minutes while IPX 8 rated device can stay underwater for a long duration.
