The Lowrance Fish-Finder may be the exact same brand that my grandfather trusted, and my dad does. Both loved to fish, but both were impatient and desired to know where the fish were. The Lowrance Fish-Finder, always at the top of the technology game, worked the very best for them. (I am sure it had been everything kept them by using a quarter 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 that he served within the U.S. Navy, Then when he explained that Lowrance was the best product for the price. Grandpa were built with a older unit, actually he'd several in the time but the last was the Lowrance X 15. If he were still with us I know he'd possess the H.D.S.8. Much like I actually do.
My dad on the other hand often uses his Lowrance H.D.S.7 to pre-load routes before an extended fishing trip, Then he would edit them in the end were underway. The Lowrance H.D.S.7 allows Dad to keep routes for future use.
While pop's (my step father) Loves the Lowrance H.D.S.10 it's 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 the Navionics (R) World Background map (non-Americas) both very useful to him.
Starting out in 1957, the first Lowrance Fish-Finder went for $150.00 while some went for $2000.00. These were then and I believe now the best value for the hard-earned dollar. There are lots of internet sites where you can read about various Fish-Finders. But buying the right Fish-Finder for you, and also the type of fishing you'll be doing whether it's a hand-held model or an H.D.S.-7. The Lowrance Fish-Finder is the fisherman's dream, because it not just enables them to see where the fish are, and can also show you should there be weeds of other obstructions that may be a hindrance. They use sound navigation and ranging (SONAR) technology to emit a digital sound signal that echoes to the unit supplying the underwater information. This really is similar to what dolphins and bats do naturally.
