In this lowrance hds 7 gen 3 review, we will see some consumers comments. How they feel after using this unit.  So here are some users comments.

Love this unit

By Michael

Love this unit. Simple to use yet has a lot of powerful features. Built-in wifi let’s me connect my iPad to it to either control the unit from or run my Navionics boating app with sonar chart Live to get real-time charting on a new body of water. The icing on the cake has to be insight Genesis and its mapping. Incredible detail and once you’ve mad multiple trips on a lake that you’ve recorded sonar, merge those trips and create your own Lake charts.


Love it so far!

By Nick76

Love the unit so far…The 3d view is pretty cool, however, I find myself using the Side Scan the most. Was a little worried the 7″ wouldn’t be big enough to have 3 displays on one screen, but it’s not at all. Really clear picture, no problems with the touchscreen, although I’m glad it has the keypad as well. Wish the including mapping was more detailed and had more display options (depth shading etc.). The Insight Genesis mapping feature is pretty nice, not entirely accurate but better than the supplied maps. Easy to record, but the maps won’t display in live time, you have to upload the sonar logs and create maps online, then transfer back to the unit. Great upgrade over my last unit!


Going fishing so much more enjoyable

By Robs

Upgraded last year to the HDS7 Gen 3, Perfect for all I do boating and fishing. Added the trolling motor this year and the combination of units made me realize how much work I was doing to find the exact spot to anchor and actually start fishing. Use the autopilot to get me on the spot (time to get rods ready) and auto anchors when I am there. Wow!



By dave345

So easy to setup and use with the touchscreen much easier than the other unit. I gave my brother the Bird unit. Love the HDS7 if you don’t have one go to your fishing store and test it I bet you buy it.
