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.

Ultra High-Definition SideVü Scanning
This mode delivers stunningly clear images of structure and fish off to the sides of your boat. This makes it easy to scout a fishing area quickly, because you can see everything the first time with such amazing clarity.

Great product
Size: 19inch
Excellent quality! Highly recommend. I love that you can wheel it around to other areas and the wheels lock in place.

Good umbrella stand
Size: 21inch
Works really well. I filled it with water and it works great. The wheels worked great on the pool deck. The umbrella stands upright even in the wind here in Florida. Worth the price. Multiple pole size inserts. 2 pole security screws.

As Advertised
Size: 19inch
The product seems well constructed and rolls easily when wheels are unlocked, even with full weight. Had windy conditions recently and the umbrella was held steady.

Seems like a good product, could use a couple improvements...
Size: 19inch
Product seems fine so far, and the adjustable size for the pole is good. Areas for improvement are a larger fill valve so you could fill sand with something other than a teaspoon. Also would have been better if all four wheels had locks and not just two.

Holds 100 pounds of water
Size: 19inch
Some assembly required. Rolls easily in direction of wood grain on a deck. Very difficult to roll sideways across gaps in deck boards.
