 With the built in sonar and touch screen these are going to be a winner with all 3 sonar functions available- high/low chirp, chirp DownVu and chirp SideVu. Previously you would have had to add a sonar module to get some of thes functions but with it now all built in will be a winner.

These are cracking when paired with the GT51 transducer - Sidevu, downvu and 600W chirp fish finding in one easy package, or if you want some REALLY deep water, then you can hook up a TM265LH or TM275LH transducer for 1kW chirp fish finding ( but wont have sidevu and downvu option ) - guaranteed over 1000m on the drift!

The units have 2 transducer connectors on the back so it is possible to run both the GT51 and a 1kW transducer if you want all options with deep water capability.

Dont forget to add your charts! These are available in the accessories tab below.

Don't hesitate to call if you need clarification on what is the best options for you.

Garmin 8"multi touch widescreen chartplotter/sonar combo. The ultimate package with touch screen capability, widescreen and built in sonar.

The sonar built in includes 1kW capability dual chirp and chirp DownVu and chirp SideVu that will provide outstanding display of the underwater structure, Includes high sensitivity internal 10 Hz gps antenna- heading and position refreshed 10 times per second. Dual CHIRP sonar provides amazingly clear target separation and definition because it puts even more energy onto the target than CHIRP. It gives you the ability to show low/high, med/high or low/med on the screen at the same time, enhancing your ability to distinguish between game fish and balls of bait fish.
