The easy-to-read GNX 21 marine instrument has an inverted display with white or color digits on a black background that clearly shows depth, speed, wind and 50-plus marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent daytime and nighttime readability with high-contrast digits scalable up to 36 mm.
The GNX 21 is the first glass-bonded marine instrument with a combination of directly driven LCD segments and a dot-matrix field to display graphical information. Its low power consumption - (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight) - is perfect for use on sailboats, and provides a valuable instrument for cruising and fishing. Fully customizable user profiles display wind, depth and speed data. Plus, the GNX 21 includes an auto-scroll feature that rotates through data screens for hands-free operation. It can be installed with the included low profile flush mount or an optional flat mount for the ultimate glass helm solution and custom look for your boat.
Easy-to-read DisplayUnique high-contrast hybrid display features large, easy-to-read digits scalable up to 36 mm tall. Offers excellent clarity in direct sunlight, at dusk, or at night. The dot-matrix section can show additional details and/or graphical information.
Glass-bonded DisplayGlass-bonded display helps prevent fogging, and the anti-glare lens finish increases visibility.
Customizable Color DigitsChoose from 7 different backlight colors, or even create a customized color, to achieve the screen that provides optimum readability for you.
Customizable User ProfilesFully customizable user profiles allow you to choose from 5 available display configurations for sailboat or powerboat user-profiles: single, dual and triple function, plus gauge and graph mode to display wind, depth and speed data, or customize the pages to display the marine and boat data that is most important to you.
Auto ScrollSet your display to automatically cycle between pages at a speed you set for convenient, hands-free operation.
Low Power ConsumptionPerfect for sailors who want to sail for long intervals without having to run a motor or generator to charge batteries. The GNX 21 uses only 25 mA with 350 mW daytime usage, requiring no backlight and just 400 mW with a mid-level backlight setting at night.
NMEA® 2000Monitor more than 50 marine and boat parameters, including GPS speed, water depth and temperature, wind direction, and wind speed from the NMEA 2000 bus. You can also add a NMEA 0183 device using the optional 7-pin bare-wire power/data cable

Where do I start! This man is a genius, I may have ordered a amateurs dream from this man, went all out on garmin products from gpsmap screens to the live scope lv34 and to juice them up I went with all powerhouse batteries and charging units! Well now on the boat I’m staring at this out dated minnkota and it just looked out of place so I went ahead and ordered up the KRAKEN! I can’t stop bragging on how much you have helped me, even face timing me on the water to fine tune my Livescope, there is no big box store that could even come close to offer this level of customer service! You will forever be my go to company! Thank you again!

Very fast shipping. Very knowledgeable guy to deal with. I inquired after hours and Chad responded quickly and chatted with me for way longer than necessary because I knew nothing about livescope. Who offers there cell phone number to call with any install questions??? Chad does. I got a friend request from him and accepted. Felt like I bought from someone who values my purchase as well as my friendship. We may never meet but I feel like I have gained a great friend. Thanks Chad for all your time spent explaining what I wanted and giving me choices. This won't be my last purchase..

It has been a pleasure dealing with Chad at Chaddy Boys! I had contacted him many times on the phone and has been very helpful! I felt like we had been old friends for a long period of time! Chad sent me many quotes and was very helpful on choosing the electronics setup I was seeking! I ordered my unit and received it on exact date I was quoted! I will definitely be buying from Chaddy Boys again!

This 16 volt battery and Run and Gun Charger is the only way to outfit your boat. Fish all day with no worries. Chad is very knowledgeable and helpful with the everything you need for a great day on the water. Now just waiting for a 36 volt to have the perfect setup. Thanks Chad.
Update* Well we just installed the second battery and run and gun charger. Took out 3 lead acid and about 120 lbs. Looking forward to the new system. Gonna be awesome. Thanks again Chad
