This mode also integrates two Sonars into one. The Flasher mode is excellent for seeing different levels of depth. I was able to see the obstacles and arcs in the water representing fish through the Traditional mode. The pictures we received were both accurate and sharp. The Power RMS enabled us to go deep in salt and freshwater. Once we used the different modes, I knew this was the ideal unit for anglers. Although I did discover a few disadvantages, I am giving the Striker 4 an excellent review. One of my favorite features is I can see the speed of our boat and the temperature of the water. The CHIRP Sonar transducer offers smooth and clean water flows for a sharp image. We found our way through the river with no issues. The Striker 4 includes a GPS for both hot spots and docks.
If you are interested in high-speed watersports, this is not the right unit for your needs.
The device withstood waters one meter deep for a full 30 minutes. I was impressed a fish finder in the lower price range offered an IPX7 waterproof rating. When we moved from shallow to deep waters, the scaling imagery was uninterrupted and extremely smooth. The Garmin 4 offered a lot more features than the units selling for approximately the same price. I had a clear picture of everything swimming beneath our boat. I have used the CHIRP sonar technology and built-in GPS on both rivers and lakes. The first time we used the device, we noted a definite improvement in our fishing. The Garmin 4 has a built-in GPS, side imaging and a very friendly user interface. The unit was a good fit for my budget and offered excellent features. We found the Garmin Striker 4 is the perfect solution for fishing from a smaller boat.
