  • Instant turn on with near silent operation and low power consumption

Featuring 250 W of power, GMR Fantom 254 is their most powerful 4' solid-state radar. It uses MotionScope technology to detect and highlight moving targets in different colors, which helps you avoid potential collisions, find flocks of birds and track weather. It includes Pulse Compression technology that provides high-resolution imaging and maximizes energy to help you detect and identify targets. It has a detection range of 20’ to 96 nautical miles.

You get excellent close- and long-range target detection from as close as 20’ to 96 nautical miles, even in fog or rain. The narrow horizontal beamwidth provides a high-resolution image, and the high antenna gain picks out weak targets at a distance. This radar paints a clear, concise image of the shoreline, other vessels and impending weather — right on your Garmin chartplotter. Get consistent target positions, excellent target separation that helps you distinguish large targets from small ones and adjustable rotation speed for fast screen updates.

GMR Fantom uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions, find flocks of birds and track weather formations. The Doppler effect is the frequency shift in the radar echo due to the relative motion of the target. This allows for instant detection of any targets moving toward or away from the radar. MotionScope highlights the moving targets on the radar display so you can navigate around other boats or severe weather — or toward fishing spots where birds are feeding at the surface.

A fading "trail" is left on the screen to help you quickly and easily identify moving targets and potential collision threats. Trails are corrected for your boat’s rotation when an autopilot or heading sensor is connected to your Garmin network.

Where there are birds on the water’s surface, there are fish below it. Auto Bird Gain helps you locate flocks of birds at the water’s surface where baitfish are likely to be found.

Dynamic Auto Gain automatically adjusts to your surroundings for optimal performance in all conditions. Dynamic Sea Filter automatically adjusts gain to changing sea conditions with user options for low, medium or high filtering.

You can increase the size of targets on screen to help differentiate from noise, or reduce the size to sharpen shoreline details.

The single radar antenna can display radar images on your chartplotter map page side by side, with independent range settings and controls for both close and long range. One or both ranges can also be viewed as a chart overlay. An autopilot or heading sensor is recommended for best results.

Mini-automatic radar plotting aid (MARPA) tracks up to 10 selected targets, helping you keep track of other vessels and avoid collisions.

This provides redundancy and the ability for each display unit on the boat to select data from 1 of 2 different radar sources.

Set the safety zone, and receive an alarm when an object enters the zone.

Variable range markers (VRM) and electronic bearing lines (EBL) allow rapid measurements of distance and bearing to vessels and land. It fits the selected radar range to the vertical size of your display to show more forward-looking radar returns on screen and make it easier to interpret target distances.

All Garmin radars are designed to be easy to install and easy to use. There are no complex user settings to adjust; just install your radar, and start using it. You can rely on the GMR Fantom radar to provide reliable, optimum performance in all conditions.

Great for dogs
Color: blue
My dog is obsessed with this! I put plain yogurt thinned with homemade broth in it and he’s entertained for a good 15 minutes, as well as being fairly calm afterward.

Great bowl, would love this in a larger size
Color: blue
This is a great way to treat your dog! I filled it with a bit of plain yogurt drink diluted with water, and my dog absolutely loved it. It only took him about 3-5 minutes to finish it, but he’s about 60lbs, so maybe a bigger size bowl would be better for him. Max capacity of this one is 190 ml. You do have to monitor your dog with this bowl - mine tried to dismantle the bowl when it was empty, trying to get more out of it. Overall I think it’s a fun way to get your dog to drink a little bit more with diluted yogurt, broth, etc.

My dog loves it!
Color: black
Kudos to whomever created this! I have a super attached (med) dog that follows me from room to room alllll day. The first time I put this down he went right for it and didn’t even notice i had left the deck. He is very food driven. I used bone broth and pumpkin puree, which was a hit but once I used the apple sauce… HUGE hit. My only complaint is that it doesn’t come in an XL size. My dog can empty it in under 3 minutes..so he doesn’t get relaxed or sleepy! it does splash out a bit from the top so I use it on his food mat or outside..my sister can’t stand the noise the ball makes. I wasn’t diluting enough so the ball doesn’t move smoothly in the video, but it really does work! The cover is very well made and sturdy. I didn’t notice it sliding around at all. My dog also did not try to get the ball out (loves to tear apart toys) or tip it over, but I could see that happening. I wouldn’t use unsupervised unless you have a small dog. Please make a larger size!!!!

Works but the bowl is wacky
Color: blue, Color: blue
This slow feeder is actually a very good idea and my dog likes it. I blend plain, unsweetened yogurt with a little powdered pumpkin & apple pectin and thin it down with water so the roller ball can easily rotate. It's sturdy and it doesn't slip on the floor, which is good. However, I give it only three stars because the bowl inside is a ridiculous design. Instead of the inside surface being a gently sloping, smooth surface, the "legs" underneath protrude up through the inside (see photo). It makes stirring and cleanup much more difficult than it needs to be. Presumably, it's made using injection molding so it should be easy to design it with a smooth finish.

Happy licking brain stimulation!
Color: black
We have a very active 1 year old field golden and we needed something else to stimulate her brain. This has worked out beautifully for that. At first she would want to try to pick it up or move it with her paw but a few corrections and training and she’s learned to just lick at it. It stays well planted in the floor and doesn’t tip over. I had to knock it one star for its ease of use and cleaning. The inside bowl has “fins” inside that make it difficult to stir things up and mix together or to clean. Other than that minor gripe we really love it and would buy again. The enjoyment our girl gets out of is definitely worth the money. It’s been through the dishwasher several times and show no signs of wear and tear so it’s well built. Happy licking!!!
