Garmin GPS73 Mounting Bracket

We don't normally advertise books but this is a good one and worth a read. This evidence based book explains how colour echo sounders work, how to operate them and how to interpret the information recorded on the display monitor. Packed full of over 130 images including screen captures, diagrams and full colour photos, this easy to read and understand book will help even the most experienced fisher gain more from their colour echo sounder/fish finder. John Adams comes from a seafaring family where all the men went to sea, serving on merchant ships, deep sea trawlers, or whalers.

If you are after a good simple colour fishfinder with GPS then this is a great unit to look at. It has a 3.5" 480 X 320 HVGA waterproof screen with an internal high sensitivity GPS receiver. The transom mount transducer is dual frequency and operates on 77 and 200 kHz giving you a usable depth reading of up to approx 120m. You can store up to 5000 waypoints and it has all the audible alarms including depth and shallow water.  

The powerfully simple 4.3-inch colour Garmin Plus 4cv is a combined fishfinder with built in GPS so not only can you see your speed on the screen but you can mark and return to your fishing hotspots with ease. It includes an all-in-one transducer that delivers both advanced Chirp 77/200 kHz and 455/800kHz Garmin ClearVu scanned images simultaneously on a horizontally or vertically split screen. The images provide the clearest possible sonar picture of fish returns and nearly photographic structure detail under the boat. Includes a quick-release tilt/swivel mount plus transom and low-profile trolling motor transducer mounts to make installation a snap.
