I have tried several, though not this brand and have returned every one that I have purchased. Most times I cast it out on the water and the wifi connection between the sensor on the water and the screen device constantly loses connection. The other issue I have is that in order to cast these types of readers out, you need to carry an extra rod or constantly change what you have going on.. most do come with those little eyes that slide up and down your line for easy connection, but i dont like anything extra on my line.
Please let me know how these work out.. I did notice that these were more expensive.. if they are legit, I'm in.
