Garmin echo 100 fishfinder review with what is best, good and bad

garmin echo 100 fishfinder

The Garmin echo 100 fishfinders is ideal for consumers looking for low budget fish finder products. Even though the price is a bit lower when compared to other fish finders like the Garmin echo 500c or the Lowrance fish finders.

It is similar to the Norcross Hawkeye f33p with the exception of their price difference with echo 100 costing a little bit higher than Hawkeye.

I will like to dive into the deep functions and discover why this product is superb for both professional and amateur fishermen and anglers. The device is very small but with great features and powerful technology.

With a gray-scale display which enables to limit the rate of it power usage by displaying in black and white colour mode. If this product was made to display in colour mode, the consumption of power would not have been stronger and longer in duration as it does.

With the popular state of the art Garmin fishing tracking technology, this device is all any fisherman need when looking for a low budget but yet with almost all the great features, a bigger fishfinder will exhibit and also with most of the required features of a standard gps position system requirements.
