GMI™ 20 Marine Instrument Display

Perfectly Designed for Power & Sail Vessels

The GMI 20 digital marine instrument display is perfectly designed for both power and sail vessels. Designed to clearly show depth, speed, wind and 100+ marine and vessel parameters, its large, bright 4" color display with extra large digits is easy to read at a distance and 170 degree viewing angle.

A glass-bonded finish lens prevents fogging and increases contrast. Daylight readability is enhanced with a high contrast color scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control. Screens can be set to auto-scroll, cycling between pages automatically without your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customized for powerboat, sailboat, fishing, engine/fuel, plus several other user-specified profiles. Power is supplied by the NMEA 2000® network.

In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the GPSMAP® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.

Stylish Aesthetic with Functional Limitations
Color: Black
This desk organizer offers a sophisticated look that complements modern furniture and decor quite well. The combination of aluminum and walnut creates a professional appearance that effectively tidies up a workspace or nightstand. I particularly appreciate the soft-touch base, which provides a safe surface for delicate items like phone screens or watches, ensuring they remain free of scratches. Additionally, the materials are very easy to wipe down and maintain. However, the build quality does not entirely justify the premium price point. The aluminum components feel more like thin, shaped sheet metal rather than a solid, high-end material. While the walnut accents are a nice touch, they lack the weight and substance I expected for a valet tray in this category. The primary functional drawback lies in the magnetic adjustment system. The magnets are relatively weak, meaning that accidentally bumping a divider while reaching for an item can easily shift the layout. This requires frequent readjustments, which can be frustrating during a busy workday. Furthermore, the magnetic rails can interfere with other metallic or magnetic objects you might try to store. If you are looking for a purely aesthetic upgrade to organize lightweight items, this tray serves that purpose, but it falls short in terms of stability and material density.

Love the customizable dividers
Color: Black, Color: Black
I really like this desk drawer organizer tray. It comes with two removable adjustable dividers that are magnetic. They have a strong magnetic pull and stay in place and do not move or shift at all. I love the overall look of it. It’s very sophisticated looking. It can be suitable for a man or a woman. If it’s into my drawer perfectly and I love the smooth modern design of it.

A nice customizable organizer.
Color: Black, Color: Black
This is a nice organizer for a drawer or nightstand. Comes in a box that is not overly bulky and is well protected. It's quick and easy to adjust and put together. the seperators are magnetic so you can customize it to fit your needs. There are two cut outs for charging cords and it fits a phone easily along with other accessories. The unit feels solid and well built, it has a good weight to it. I do wish the deviders were a bit easier to get square, but that's more just my idiosyncrasies.

Nice Desk Organizer
Color: Black, Color: Black
This particular desk organizer has the little strips of wood that each have a magnet installed inside them. This allows you to move the wood strips to different locations and adjust the areas to fit whatever size item you want to put in there. It's very easy to just move them around and the bottom of the tray has a nice material in it that prevents scratching the items you place in there. The usable area on the tray is 12-1/2" x 8-1/4" x 3/4" and the overall size is 13-5/8" x 8-3/8" x 1". It fits nicely in drawers or simply having it sit on top of a desk to hold items. It also is made out of good quality and is very sturdy.

Great product quality
Color: Black
This had literally everything I was looking for, but… just too large for the area I wanted it in. Check the measurements and compare that to your actual space. If they had about 1/2 to 1/3 of this size I would snatch it up in a heartbeat. It has a groove for your phone charging cable and the moving magnetic dividers are genius. I’m looking for something to put on my nightstand to allow the phone to charge at night but face down. Extra section for earrings or hair accessories, etc would be great. This has that potential. Just needed it smaller.
