The Lowrance Fish-Finder may be the very same brand that my grandfather trusted, and my dad does. Both loved to fish, but both were impatient and wanted to know in which the fish were. The Lowrance Fish-Finder, always towards the top of the technology game, worked the best for them. (I am sure it had been all that kept them from using one fourth stick of TNT)
My grandfather loved new technology, having worked for McDonnell Douglas, and on the Apollo missions. (I've the NASA pens to prove that. ) Before he served in the U.S. Navy, So when he explained that Lowrance was the very best product for that price. Grandpa had a older unit, actually he had several in his time however the last was the Lowrance X 15. If he remained as with us I understand he would have the H.D.S.8. Just like I actually do.
My father on the other hand often uses his Lowrance H.D.S.7 to pre-load routes before an extended fishing trip, He then would edit them while we were underway. The Lowrance H.D.S.7 allows Dad to store routes for future use.
While pop's (my step father) Loves the Lowrance H.D.S.10 it is ideal for his fishing-boat using the built-in cartography choices including Enhanced U.S. Base map and Coastal coverage of the U.S. and also the Navionics (R) World Background map (non-Americas) both very useful to him.
Starting out in 1957, the very first Lowrance Fish-Finder went for $150.00 while some went for $2000.00. These were then but now the cost effective for your hard-earned dollar. There are many web sites where you can read about various Fish-Finders. But purchasing the right Fish-Finder for you, and also the kind of fishing you'll be doing whether it's a hand-held model or perhaps an H.D.S.-7. The Lowrance Fish-Finder is the fisherman's dream, because it not only enables them to see where the fish are, but will also demonstrate if there are weeds of other obstructions that may be a hindrance. They will use sound navigation and ranging (SONAR) technology to emit a digital sound signal that echoes to the device supplying the underwater information. This is much like what dolphins and bats do naturally.
