I am not sponsored by Johnson Outdoors/Humminbird and this is just my humble opinion.
I have run a H-bird 1197 for the last few years as my primary locator, and had until this spring a 997 also. Both units have performed well above my expectations. Previous, I had been a hard-core Lowrance LMS-350 A user. Without a doubt, the humingbird is the leader in technology, user friendly, and variety of featured units in different budget ranges. If and when anything ever happens to my 1197’s, I will replace them with the equivilant H/Bird products.
I have had a couple of clients now hire me to go out in their boat and instruct them on the use of their electronics. What a couple of guys thought would take them days to figure out, actually only took a few hours. That included time on the water to capture tons of screen shots (as well as review all the menu features) and time to work with the H-bird PC software to edit waypoints, updates, integrated Google Earth, creating back up files, and most importantly – learning more about the structure they fish from reviewing the screen captures.
If you get an opportunity to get on the water with a Hummingbird owner, take advantage of it to check out how easy this technology is to use!
