Review of Humminbird 718
| Overall Rating | No Ratings |
Humminbird has been in the marine electronics business for over 40 years and they are one of the most respected names in the business due to the ease of use and full functionality of their equipment. The 718 keeps this tradition in spades. The screen size measures 5 inches diagonally and is ample for viewing subsurface objects. The images are further enhanced with 16 levels of gray-scale which helps distinguish between fish and other structures. The resolution measures at 320×320 pixels which will give the user plenty of definition for clear and accurate representation of provided images.
The transducer is a dual frequency sounder that emits both a 200 kHz and an 83 kHz signal. The 83 kHz signal provides a wide 60 degree band that is suitable for shallow waters while the 200 kHz signal allows for a 20 degree arch that can reach depths of up to 1,000 feet for deep water surveillance. With Truearch technology built in to the unit, the exact depth and size of the fish targets can be ascertained. Parallel signal processing is used to eliminate noise and other undesirable sonar echos to provide pristine imaging.
Once the signals are emitted by the sounder module and returned to the main control unit, there are other technologies that Humminbird uses to accommodate the needs of nearly any angler. One such feature is what Humminbird refers to as Switchfire. With Switchfire the user can customize the level of detail that is displayed on the monitor. Max mode provides views of absolutely everything under the water including bait, weeds, trees and thermoclines. However, in certain circumstances it may be of some benefit to simplify the display and eliminate some of the clutter. In such instances the user can quickly shift over to Clear Mode to get a more abbreviated look at the underwater activity.
The 718 is fast, powerful and easy to use. It’s also expandable. When the need arises, the unit can be connected to a GPS antenna for navigational and mapping capability. Humminbird has you covered with the 718.
