GCV™ 20 Ultra HD Scanning Sonar Black Box with GT34UHD-TM Ultra HD Transom Mount Transducer

Add Ultra High-Definition Scanning Sonar to Your Compatible Chartplotter
The easy-to-install, networkable GCV 20 sonar black box allows you to redefine clarity and detail. Add any of the 3 GT34UHD transducer models to see stunningly clear Ultra High-Definition ClearVü and Ultra High-Definition SideVü scanning sonars — with frequencies ranging from 0.8 MHz (800 kHz) to 1.2 MHz (1,200 kHz) — to your compatible chartplotter. And you can share sonar images seamlessly across multiple networked chartplotters as well as networking Panoptix™ all-seeing sonar. It includes a max power output of 500 watts.

Ultra High-Definition ClearVü Scanning
This mode provides brilliant image clarity of structure and fish below your boat at greater depths than other high-frequency scanning sonars by putting more power on targets via a downward-facing element.

Perfect phone charger stand with mag safe charger
Color: Black, Set name: With Cable & Adapter
Works perfectly. I have had this for a month and as long as you have a magsafe case on your phone, the phone stays on and charges. At night if you place it on the charger in the landscape position it can work as a clock and/or outside temp. It is not flimsy. So many I saw required that you buy a magsafe charger to slip in the stand first, this one already has one so you just place your phone on the stand to charge. Worth the cost, would buy again.

Perfect Desk Charger
Color: Black, Set name: With Cable
Needed a desk charger for my phone, this stand is the perfect height and very compact, it's plug and play (no extras required), holds the phone perfectly at every angle, price is almost the same as an Apple mag safe charger and it charges at about the same speed.

Fast Charging
Color: White, Set name: With Cable & Adapter
Works perfectly! Charges fast and holds the MagSafe phone with its strong magnet! Doesn’t heat up and fits on the nightstand for quick pickup when needed! Works great on my iPhone 17 pro max even though it’s a heavy phone! Small and compact does not take up too much space!

Solid choice
Color: White, Set name: With Cable
Generally, I like this charger. It feels solid, it's pretty easy to put my phone on, it charges pretty well, it supports rotating the phone when that makes it easier to read. On the other hand, it's not as fast as a direct USB-C connection and there's no height or angle adjustments. There have been a couple of times where I thought the charger was very slow, but it may be that the phone wasn't perfectly located... and it might be my fault since I do have a thin cover over the back of the phone.

Perfect Combo of Speed, Style, and Stability!
Color: Black, Set name: With Cable
This Anker MagGo charger is exactly what I was looking for! It charges my iPhone 17 at the full 15W speed with MagSafe, and the magnetic connection is super strong—my phone snaps right into place and stays secure even when I bump the desk. The stand design is a major plus. It holds the phone at the perfect angle for FaceTime, video watching, or just checking notifications without picking it up. It also looks great—sleek, minimal, and very premium-feeling. No loud fans, no overheating, just fast, reliable charging. Anker never disappoints when it comes to quality, and this MagGo charger is no exception. Definitely worth it if you want a MagSafe stand that delivers on both form and function.
