  • Track targets and weather from 20’ to 96 nautical miles
  • Scan-to-scan averaging aids in reduction of sea clutter and interference
  • MARPA tracks up to 30 selected targets, helping you keep track of other vessels and avoid collisions
  • Choose from several easy-to-use settings that automatically adjust the gain or target size
  • 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.

Nice amplifier for the cost.
Style: Stereo Receiver, Configuration: Receiver
I had been using my Marantz model 22 receiver now for a couple years now with the TV, dvd player, and youtube music from my tablet. I like lots of knots and switches on my audio gear, I'm an engineer. I was getting tired of the seemingly endless up and down to adjust volume and whatever. And my inputs on the Marantz were maxed out. I searched Amazon to see what was available as a possible replacement that had a REMOTE. This Sony caught my eye. Relatively inexpensive, plenty of inputs, and specs I could trust, not a 3x4x5 box offering 220+220 watts of unlimited power! Ordered it and been using it for over a month now. Only 2 knobs, how good could that be? Well, it's remote let's me control everything without getting up. Plenty of output power, 100+100 watts of true RMS power. I didn't plan on using the Bluetooth but I tried it with the tablet, keeping the tablet by me, and it really impressed this old audiophile. I really don't have any negatives about it, even the fm sounds great. It was heavier than expected but not as much as that old Marantz. I even popped the cover. The build quality was what I consider good. I only wish I could find a service manual with the schematic for it.

Great Banana Plugs
Size: 6 Pairs / 12 pcs
I recently purchased these FosPower banana plugs to tidy up my speaker wiring, and they’ve been a significant improvement over bare wire ends. Installation is straightforward: strip the wire, loosen the two tiny set screws, slide the wire in, tighten everything down, and then screw the barrel back on. Once assembled, the connection feels secure and tight, making it much easier to swap gear around and reducing the risk of stray strands causing a short. The standout feature of this design is the dual set-screw clamp. It firmly grips the speaker wire without relying on the outer collar to “crush” it in place. I’m using 12-gauge wire, and it holds well for my setup. Initially, the plugs may fit snugly in some binding posts. Once seated, there’s no wobble, but it might take a bit of extra push the first time. The set screws are small, so a bit of precision is needed. Use a small flathead screwdriver and don’t over-tighten them. Overall, these plugs feel well-made, look clean once installed, and fulfill their purpose as banana plugs: making speaker connections quick, neat, and reliable.

Great Banana Plugs!
Size: 6 Pairs / 12 pcs
These FosPower banana plugs work very well. I have used dozens of these great FosPower banana plugs over the years, and they definitely work as advertised. When comparing apples to apples (or bananas in this case....lol), all Banana plugs work virtually the same way, and these banana plugs are no different. Strip speaker wire, unscrew banana plug cover, loosen speaker wire retaining screw(s), insert speaker wire, tighten speaker wire retaining screw(s), screw on banana plug cover, and wallah, a secure/conductive speaker/amplifier wire connector is created. Albeit, some banana plugs require the speaker wire to be splayed over a hollow post, and then they are held down by a screw-on retainer/cover. However, I much prefer these FosPower dual retaining screw type of banana plugs for their speaker wire holding ability. I always use high quality 14 gauge OFC speaker wire with these FosPower banana plugs, and they work perfectly together. I have used these FosPower banana plugs with many different speaker and amplifier brands over the years, including Klipsch, Pioneer, Polk, Denon, Dayton Audio, and Fosi with no problems at all. They just work, and work well. I have never had a FosPower banana plug break, release the speaker wire or short out, in all of the years that I have used them. Yes, these FosPower banana plugs do fit rather tightly into the connectors, at first, on a lot of speaker and amplifier brands/models. However, after the initial "squeeze" the banana plugs will lossen up, and become easier to install and remove. However, they still retain their great holding ability even after the initial squeeze. In order to overcome this initial "tightness," I usually just stick the FosPower banana plugs into a connector of an old portable amplifier, before assembling them, in order to squeeze them before inserting them into their final speaker or amplifier destinations. This is especially useful when working in tight places, where there is not much room to work in order to push the FosPower banana plugs into their tight connections firmly. Overall, I highly recommend these FosPower banana plugs. I am currently using them all over the house and shop for home theater and music listening (and testing projects). Just be aware of the tight fit in some speakers and amplifiers. Also, the 2 very tiny speaker wire retaining screws can be a challenge sometimes. Just use a good standard blade jewelers screwdriver, and be careful not to remove the retaining screws all of the way or over-tighten them. Once these things are mastered, using these FosPower banana plugs becomes second nature. Have fun!

The most legit banana plugs I could find on Amazon
Size: 6 Pairs / 12 pcs, Size: 6 Pairs / 12 pcs
NEW PREFACE:: I am kind of glad I first bought the horribly magnetic, horribly made and GOLD PAINTED Sewell crimp on plugs (some reviewers say that Sewell are better and easier to use than the FosPower, which is true in design, but in quality of materials FosPower beats them hands down!!) ... Changing from those to these FosPower plugs plus the Monoprice 90° plugs, I am flabbergasted at the difference they make in sound quality. I have heard people say that they can hear the difference and even as an audiophile I was skeptical..... but my skepticism has been completely erased by what I am hearing with my own ears. I waited a few days to make sure I wasn’t just tripping before updating this review 🤣....but it has become clear to me how much a difference plugs made from the right materials actually make!!! I am 100% serious that the bass coming out of my Polk Signature Series tower speakers has at least doubled at the same volume. I can also now turn the volume up Way past my max volume before, without any distortion and much more clarity and less harsh highs. Everything just sounds warmer in general now which is amazing!!!! This is dangerous info for me... because now I’m thinking about making some really nice custom wires to see how much of a difference that makes 🙄🙄🤣 OK onto the review of the actual plugs here~~ These seem like decent connectors. I can’t tell if they are brass or copper, but they only have a slight hint of a magnetic property when testing them with a very powerful magnet. I was easily able to fit x2 - 14ga wires into it for bi-wiring purposes, including screwing on the collar. (As seen in my example pic) The gold plating on the tips seems legit and not painted like some of the plugs from Sewell... I have tested and tried quite a few plugs from Amazon and most seem to be crap. These however hold up better than most! These and the Monoprice 90° banana plugs with the black and red rubber sleeves. The latter are gold plated copper and have zero magnetic properties. (if you need 90° banana plugs) UPDATE: still the best plugs I have found, but upon full install found two issues. One is a defect where a set of the plug threads for the barrel cover body weren’t cut right. The body’s do not tighten and stay loose because of that. Obvious issue for vibration with metal on metal... The other issue is that even though these say they can fit different gauge wires, they seem to be geared more towards 12 or 10 gauge. I am using semi solid strand 14 gauge and find that unless I fold the wire over to make it double thick, the bolts use up all the thread and seem to become kind of loose inside the body. They won’t fully seat and keep spinning no matter how much you tighten. They seem to stay secure still but I just wonder about longevity over time with vibrations. So I just doubled up the wire and they seated fine! Not the worst issue in the world, but just kind of a pain since you have to strip the wire longer than you normally would so you can fold it over. ANOTHER UPDATE: I had to remove these plugs from the wire to connect them to a crappy spring terminal amp while my better amp was in the shop. The issue I wrote about with the set screws "bottoming out" on smaller gauge wire became a more pronounced issue! I could not unscrew the set screws anymore and just had to cut the wires... So that means I will need to purchase more of these to replace the ones I cannot get wire back into. Not the best design, but still one of the best plugs I have found on Amazon.
