Humminbird 409690-1 PiranhaMax 197C DI Color Fish Finder with Down-Imaging

Humminbird 409690-1 PiranhaMax 197C DI

These claims maybe a bit of an exaggeration, but there are good qualities about this product. The big advantage is that this model has an accessory base that swivels and moves simply. For anyone fishing on a canoe or kayak, the ability to rotate, tilt, or angle the device will  appreciate. This is the standard base for the PiranhaMax, but it can be a problem when mounted to a dashboard. It is designed to be readily removed from the base, it won't work as well mounted to standard boat dashboards. Humminbird 409690-1 PiranhaMax 197C DI is the last model reviewed here.

The display unit is crystal clear and crisp. It works well in sync with the Down-Imaging and Dual Beam. The sonar offers depth capabilities to 320 feet with Down-Imaging, and up to 600 feet with Dual Beam. In direct sunlight, the color screen can be hard to see clearly. Perhaps this is the reason for the rotating tilt mounted base. The transducer requires a single 12 volt battery, not included in purchase.

The Humminbird 409690-1 PiranhaMax has a waterproof rating of IPX7. This means it should be able to withstand 30 minutes underwater up to 1 meter deep. This is a very good rating, herein lies the biggest problem with this Humminbird model. Review after review of the PiranhaMax complains about the water resistance of this device. Some claim that the device quit working after being in the rain. Some claim that getting the screen wet causes permanent damage to the display. Multiple reviews that getting it wet causes the battery alarm to keep going off, but maybe fixed by drying the device out.

For the money, this would appear to be a great little device. It is more reasonably priced than other similar ones available online. I would have to place this in the buyer beware category personally
