Experience with the Raymarine Dragonfly fish finders?

LOL, I knew it was a while back, not sure about 20 yrs but the reason I remembered was that I have never heard of anyone using one here on the site and I thought it was not a commonly used brand at the time. I've heard of them more since then but did no remember of anyone else owning one. Thanks for the reply Kent.
