I have never had a GPS and chart plotter and have been trying to learn what is available. I am looking for a good charting system so I know where I am, boat speed, and water depth. I don't fish, I just bought a 1991 Guardian 19 with a 1994 Evinrude 140HP V4, so not a need for data from the engine?

[A Raymarine a67] is available locally. It includes the charts but not a transducer ($130). I've looked at the charts and they are great for where I will travel.

Any suggestions on other units will be appreciated too.

Thanks,
Don

I'm partial to Raymarine, so I would recommend Raymarine.

Truth is, all the major manufacturers make very capable units.

Go with the more capable a68, it has chirp [pulse-compression] SONAR built-in. I would opt for the a78; the larger screen is definitely worth it. Since you don't need the networking or engine data, a reasonable, less expensive, alternative is the Lowrance Elite-7 CHIRP [i.e., the model name]; it's in the same performance class as the Raymarine Dragonfly.

There are many options available for devices that contain

--a GNSS receiver, of varying capability, some limited to just the USA Air Force NAVSTAR GPS and other more capable, and with various facilities for simultaneous satellite tracking (or "channels") and various update rates;

--a chart plotter of various sizes and color capabilities, brightness;

--embedded digital chart cartography bundled with the unit price;

--a SONAR, of various designs and performance, including conventional mono-pulse down scan, side scan, frequency modulated pulse compression, high frequency and high-resolution, and on and on;

--a transducer, of various size, power, frequency, beam width, and range;

--a NMEA-2000 network interface;

--an Ethernet network interface;

--an NMEA-0183 interface, of various number of ports, various speeds, and various configuration (single-ended or differential), with and without multiplexing capability;

--a multi-function display with abilities to overlay RADAR or AIS targets; and

--a touch screen display with or without conventional buttons.

I don't know of any method of assess all the options available and determining which one is the best choice based on some criteria, such as:

--lowest price

--most reliability

--most durability

--most logical operating system

--most adherence to standards for interface with other devices

--best after-sale support

--most compatible with personal preferences for size, color, appearance, brand, and so on.

There are just too many choices and too many categories for evaluation to ever reach resolution on which unit is the best or stands out from the pack.

To make the selection even harder, the marketplace changes practically daily in prices and selection. Rebate offers come and go in a few days period some times. Special incentives result in big price reductions. The selection of a particular unit for a small boat is a complicated process.

Raymarine is great equipment. Make sure screen is bright enough (should be) and go wider if you have budget. The touch screen stuff is awesome.

Thanks for the information, I am just looking for suggested units comparable to the Raymarine A67 performance wise. In this area (Nova Scotia) marine wise we are limited on suppliers and prices can be high. And its a learning curve to get up to speed on the technology when you've never owned one of these things before.

West Marine has them on sale - saw on website this afternoon. If my transducer works with it I might pick one up. Lowrance is pretty attractive. I have been using A57D which is a great unit but so many menus and hard to customize, screen pretty small for my aging eyeballs. And almost impossible to read with polarized lenses. That's my problem with what I am using.
