Years ago I had a portable Hummingbird fish finder which I never really found useful in specifically identifying fish
amongst vegetation such as lily pads. It was a very basic unit that showed fish as an arc and displayed rudimentary
bottom contours. I lent it to my daughter and son in law and it got broken (and never replaced)
Apparently the technology has come a long way since then and there now are units that work through your iPhone or
a tablet, show pictures by size, real shape, and even species. They also display all manner of other information.
For those of you that use a portable fish finder for fishing lakes, what has been your experience, do you use the new
age Wi-Fi units, blue tooth units, or the old style units with their own screen? What would you recommend? I am considering
the FishHunter 3D Portable, but there are others as well. They say the Wi-Fi units suck more battery life but are much
faster than the blue tooth technology.
