Anyone using the Raymarine Dragonfly 7? - Kayak Fishing Adventures on Big Water’s Edge

I fished dragonfly 7 for about a year on my Kraken. Its not too big, and easy to fish around, assuming you set it up in an ergonomic spot. I now fish a 7" lowrance, and I can tell you I won't ever fish a smaller screen again. Not that a 4" unit won't work fine... I had an elite 4x for years.

But the extra screen size does more than just look cool. It drastically increases the data you get from it. Think about it... a 200 kHz signal has so many oscillations per second (200,000 I believe). For that finite number of cycles to be graphically represented, it must be converted into pixels. The more pixels you have, the more information is displayed on the screen. Actually it's more correct to say that less information is left out of the return. Just like how you can't view a 12mp photo on an old motorola flip phone. The hardware can't handle the information being thrown at it. So you see, the bigger screen actually adds more detail and more accuracy, not just a bigger picture.
