This review is from: Humminbird 798ci SI Combo 5-Inch Waterproof Marine GPS and Chartplotter with Sounder (Navionics Gold and HotMaps Premium Charts Pre-loaded) (Electronics)

After checking the web for reviews on Lowrance and Humminbird both and finding horror stories anymore about customer service from Lowrance and wait times of months, not to mention being charged to repair units under warranty, I decided to try this out as I called them several times with questions and got excellent responses each time.

Mounted on the trolling motor on the front of the boat and I have to say it is sweet. Works exactly as advertised with no problems. SI is awesome compared to older graphs.

I have also done a software update using a sd card which worked flawlessly. So far this unit is well worth the money.

5.0 out of 5 stars Nice Fish Finder for the Price., January 27, 2010

This review is from: Humminbird 718 5-Inch Waterproof Fishfinder (Electronics)

The Humminbird 718 is an excellent choice for the angler or recreational boater looking for an affordable Fishfinder. It doesn't have a flashy color display, but I don't see the advantage of a color display for a basic Fishfinder. The simple black and white display affords a nice crisp contrast which is easy to see in bright sunlight.

You will have to take the time to carefully read the manual if this is your first time using a fish finder. The display can be very complex and confusing if you don't read the manual. The 718 is easy to customize to your own preferences. For example, I set the display to show a solid black sea bottom vs. the default setting that allows the unit to display different shades of grey according to the density of the bottom. I also customized the display to show little fish icons for fish instead of the default setting which is an arch representing the reflection of the sound. I like simple and easy to read! I don't think I would like it as much if I couldn't customize the readout.

The 718 can also be paired with a GPS antennae, but don't expect the 718 to become a chartplotter with the addition of GPS. With the addition of GPS the 718 does not have the capability to store or display charts or maps so your route is displayed as a black line on a grid with no visible shoreline. I find the GPS very useful for saving waypoints, routes, and displaying the speed and location of the boat.

I give the Humminbird 718 5 stars for being affordable and easy to use. I recommend adding the GPS receiver.

1.0 out of 5 stars DO NOT BUY UNTIL HUMMINBIRD GETS PROBLEMS WORKED OUT!!!, June 27, 2011

This review is from: Humminbird 798ci HD SI Combo Fishfinder and GPS (Electronics)

I purchased this unit in March, 2011 and used it 3 times. The second time the GPS tracking would not track under 2mph and would only show a donut, which is very frustrating if trying to stay over a marked fishing spot.

I contacted Humminbird and they said to download update 5.410 and it would fix the problem. I did this.

I used it the third time and the GPS tracking problem had not been fixed with the new update. This time out the depth reading began going crazy. I was in approximately 180 ft. of water and it was reading all the way down to 1.7 ft. and bouncing all over. I spoke with 3 different Humminbird techs via phone while I was on the water and we tried all kinds of settings and could not fix the problem.

Humminbird is going to send me a new transducer to try, but I do not believe it will fix it. If not, they said I will have to send the unit in to them.

It is ridiculous to pay over $800 for an item and it not work correctly, so I would not buy this item until Humminbird gets these issues resolved if I were you.
