I've got a Lowrance x-52. It has the same features, it's just a little smaller screen and case. I love it. I don't think you can beat the Eagle/Lowrance film supertwist LCD screen as far as monochrome models go. It has quite a few features. It has a digital flasher. I've got the speed sensor for mine. It works pretty good at higher boat speeds. It will change all of it's features automatically depending on what the unit detects or you can set everything manually. You can also veiw most features in a split screen. The x-52 is normally around $150 - $200 when I bought mine, but I found one brand new on Ebay for $85 and bought a speed sensor on Ebay for $20.
