Took the Ventura out today just to play around Simrad's NSS8 embedded sonar. Worked nothing but shallow water slow and fast. The NSS8 is connected to an Airmar TM260 transducer .... great pair (at 37 mph it was marking fish) plus it is connected to the 740 via N2k backbone. They play well. I use the Garmin as my primary navigation CP and the NSS8 and my FF.

Here's some video (if you have a high speed Internet connection click on the HD icon after the video starts to run).

Airmar TM260 .... running hard. Not much spray from the install found the sweet spot for engine trim and rpm's.

Tom--The pseudo three-dimension chart presentation on the GARMIN 740 is very nice. I can see how you could easily come to prefer that presentation of the chart data.

Jim ... the Garmin G2 Vision 3d is very nice ... easy to view and use.

Simrad NSS8 embedded sonar pictures.

Conditions ...... overcast windy day running in brackish water. Water stayed 72 degrees with varying amounts of biologics.

Auto gain ...... slow speed png?t=1337601805

Manual gain .... high speed png?t=1337601806 png?t=1337601806

Running hard ... I found the TM 260 to be a very good transducer but because of its size you really have to adjust the gain and color when running. The picture will vary in relation to engine trim, tab use, and engine rpm's. Simrad has done an excellent job when it comes to adjusting these parameters. All you have to do is touch the item you want to adjust then use the rotating knob to adjust up or down. png?t=1337601806 png?t=1337601808 png?t=1337601806

Slow speed ....... png?t=1337601811 png?t=1337601815 png?t=1337601819 png?t=1337601821

Next weekend I'll do a deep water excursion 200 - 2500 feet.

In this picture you can see the Simrad NSS8 is using the Garmin 740 for positional, SOG, COG data. It is passed to it on the N2k backbone.

Note: All these inputs are selectable on both the NSS8 and the 740. As I mentioned earlier the two units work well exchanging data. png?t=1337601821

Tom--you may have shown us before, but let's see the big TM260 transducer. Give us a link to pictures of it on your Whaler transom.

The TM260 is a good transducer just big. TM%20260%20Install/3.jpg?t=1327870406 TM%20260%20Install/9-1.jpg?t=1328053749 TM%20260%20Install/7.jpg?t=1327870422

The one on the right is an Airmar P66. TM%20260%20Install/IMG_1558.jpg?t=1327532130
