Humminbird 409460-1 688ci HD DI Internal GPS/Sonar Combo Fishfinder
Humminbird 409460-1 688ci HD DI functions work in very rudimentary ways. The layout of the software is set up in blocks that separate readings for water depth, temperature, or speed. This allows the information on the screen to be more easily read, even in various weather or lighting conditions. The unit can measure depths of 1500 feet. The transducer is XNT-9-DI-T, which has been a favorite among users of similar fish finder combos made by this company. This is the complete package deal with all the features of top dollar models. And I felt that the high quality color display is a welcome improvement on other Humminbird models.
There is one common issue with this fish finder having to do with the GPS. When the unit is shut off for more than a couple hours, it initiates a cold boot start. This is followed by a waiting period for the GPS lock, usually about 10 minutes. The GPS tends to have less sensitivity than users will likely expect. This might happen more frequently in overcast weather conditions.
Anyone can do the set up right out of the box and technical support is available direct by the manufacturer. Installation of the unit is simple and mounts readily to any style boat dashboard. This makes it perfect for the amateur or experienced fisher. I consider this a wonderful gift idea for fishing lovers that won't become obsolete over time.
