Standard Horizon CPV550 Review

The Standard Horizon CPV550 features a massive 12-inch color screen and will do about anything but cook dinner. It’s a full-function chartplotter packed with a VHF and a number of bonus capabilities. Plus, it has the ability to hook up to an optional black box sounder and AIS receiver. The

Standard Horizon CP390i Review

The Standard Horizon CP390i is built around a very high resolution 7-inch display screen that packs 800 by 480 pixels of resolution. Compared to its smaller brother, the CP390i is a big step up in screen space, pixel count, and the ability to see fine detail. This Standard Horizon chartplotter

Standard Horizon CP190i Review

The Standard Horizon CP190i is built around a bright crisp 5-inch display screen and features a built-in 50-channel GPS sensor. It also comes with preloaded cartography and is one of the least expensive standalone chartplotters on the market today. The preloaded charts in this Standard Horizon GPS chartplotter provide detailed

Standard Horizon CP180 Review

 The Standard Horizon CP180 we tested ships with an external Smart GPS sensor. This unit is one of the least expensive standalone chartplotters on the market today. Another version, the CP180i is equipped with an internal GPS sensor. Our test unit comes with a base map. More detailed cartography is

Standard Horizon CP1000C Review

The Standard Horizon CP1000C is a large screen colorized version of the original CP150 Standard Horizon GPS chartplotter. It measures just over 13.5 inches wide by nearly 9 inches high and is equipped with a huge 10.4-inch color screen boasting 640 x 480 resolution. Well known in the marine electronics

Sitex Colormax Wide

The Sitex ColorMax Wide chartplotter we tested was paired with the Sitex ES502 black box sounder to provide both plotting and sounder capabilities. This unit will also accept radar inputs from a Sitex radar sensor. The ColorMax Wide comes with a quick-release bracket that allows for easy removal of the

Sitex Colormax 6

The Sitex ColorMax 6 will interface with the Sitex ES502 sounder and AIS. The case measures just over 8-inches wide by 6-inches high and is under 3-inches deep. ColorMax 6 comes with a quick release bracket that keeps all wiring on the boat. A nice feature but, in our opinion

Sitex Colormax 5

The Sitex Colormax 5 ships with a Smart GPS sensor. The unit does contain a base map but to get detailed cartography, tide information, and buoy data you’ll need to add a map card. We filled the unit’s single card slot with a C-Map Max chart card covering South Florida

Sitex Colormax 11 Review

The Sitex ColorMax 11 is a large screen all-in-one chartplotting system. It will interface with the Sitex ES502 sounder, a couple different models of Sitex radar, AIS, and video. This unit will take up some panel space as it measures just under 13-inches wide by nearly 9 inches high. ColorMax

Simrad NX45 Review

The Simrad NX45 is a large screen next-generation multifunction display with an onboard dual frequency fishfinder. This MFD can also interface with a variety of other devices and sensors. The first thing I noticed about the NX45 when I unpacked it was how light it was—by itself the display unit

Northstar 6000i Review

We installed a Northstar 6000i networked system, now a Navico brand, for long-term testing aboard our 25′ Contender. The Northstar GPS system included a 10.4-inch and 8.4-inch display, a Northstar black box sounder, and radar. Most but not all connections in the Northstar network are easily made with supplied cables.

How We Test Chartplotters

Normally we test marine chartplotters aboard our one of our test boats. We aim for a competitive analysis by comparing at least two or more like units during each review. One of the most important features of any gps chartplotter or chartplotter fishfinder combo unit is how well you can
