Default Garmin 7610xsv Initial Sea Trial

Had my new 7610xsv installed yesterday with b75m transducer and GT30-tm sidevu and downvu. Let me preference this review by saying that I am by no means an expert when it comes to electronics. This is the first decent system I have used since running the Ratheon equipment on my Dad's boat 15 years ago. With that said the Garmin unit itself is pretty awesome. Touch screen is very sensitive like an iPad and the menus are easy to navigate. I do a lot of diving and thought that I was going to split the screen into 3-4 windows so I could utilize all the sonar capabilities. I quickly figured out that this is not practical on a single 10" screen. I wish I could have got the 7612 but I already went way over my budget with this setup.

I didn't have a lot of time today, but ran out to a public wreck and then to an area that I had marked a year ago with a less superior machine. When I pulled up to the unknown spot I found a charter boat sitting on it and the bottom blew up! This area was most likely a spot of broken bottom which is very common for the area I was scouting.

The sonar on the B75M is great, especially at low speeds. I thought it would read a little better at 30 mph but I guess it's not bad. Sorry for the poor quality of pics, was using my phone in the shade. I know nothing about transducer settings, so does anyone know if there are any specific settings that I need to adjust in the unit to get optimum performance?

I was not impressed at all with the sidevu. I don't see myself ever using it as it does not seem to work like shown in the demo. Maybe it would be better in shallower applications like lakes, but in 55' of water it showed nothing beneficial. The downvu was ok, I think it would be better suited for wrecks or large structure. The split view between the traditional and downvu is pretty cool as you can see the difference between the two.

The preloaded charts are pretty basic. They show all your land masses, channel markers, etc but not much info for depths, contours, etc. I think I will upgrade my maps but haven't looked into the cost of that yet. The Garmin helm and Bluechart mobile apps are really cool. I took my iPad out today and had charts on the iPad and sonar on the MFD. The iPad doesn't have enough brightness to be used as a chart plotter, but will be useful for planning a trip beforehand as you can transfer waypoints and routes very easily. It is also easier to use the iPad to scan through your waypoints and then hit go to. You can do the same thing with an iPhone as well.

I also had a GFS10 installed which is a pretty handy tool. Does anyone know if there is a setting on this that you can track your total fuel consumption for the trip? I assume there is but didn't get enough time today to figure it out. Overall review for this unit is very satisfied after the initial trip. Next weekend is the spearfishing tournament and we will really put it to the test. It was a long wait to finally get this installed but seems to be well worth it.

Nice job and keep us updated as you tweak it. What do you have for a Side/Down Vu transducer set up?

Thinking of going with 2 10" units. How is it when you spit the screen?

Think you could post a picture of the placement of your GT-30 transducer placement?

A note here..

When using the Side Vu....Auto is not always best..but try also to set the range manually.
One will find in many cases the best results for bottom and targets less than 50' to 100' to the side are gained in the manual range setting rather than auto etc.

One will be surprised at the difference.

Thanks for the advise Gil, I will try that for sure. Most of my fishing is on live bottom, so I will try tweaking the settings and see if it helps. I think the sidevu would be beneficial for finding wrecks, especially if you were trying to find one that wasn't on public numbers. I'll give it a good work out next weekend and post the results.

Take a look at the 3rd picture I posted. If you had a pair of 10" screens you would be set. Splitting the screen still gives you plenty of area to view. For a single display a 12" or 16" would be nice, but if you are doing a pair, I think you'll be good with 10s. Just depends on your preference. Bigger is always better in this situation.

Exactly..for structure ..and not for finding fish

It took me be a good bit to really learn how to use the Side VU..but now I am very comfortable with it.

How far to each side does the new 7600 series read ?

Agreed, manually managing the side scan function is where the magic is. Practice near a known structure helps you figure out what settings work best for where you are at. When you find the sweet spot it will be a holy crap moment.

Supposedly 500 - 750 ft depends on which side view transducer you have installed.

you can also take screen shots by pressing and holding the home button if you have an SD card in one of the slots. They are saved to the card and are much better than what you get with a camera.

From my 5212 but you get the idea.

Please keep us posted. IMHO, the Side Scan feature is one thing Garmin is touting as a leap in technology. I hope that's true.

Garmin's Side scan over the last year and half has been very well received by many of its end uses.

Here is a link to few of the end users screen shots ..many were sent in to Garmin as entires into the Garmin Screen Shot Contest.
One of the winners was a THT memeber.

All the side scans are pretty good. I've never seen an image from one that I didn't think the other could recreate. The 260kHz will be interesting to see what range limits side scan can be pushed to.

Gt30 is the same elements at the gt50. If you've seen images from it, you've seen images from the gt50.

Curious if you have a Vision card in one slot and a blank SD card in the other can you set pics to be stored on your blank if vision card is not write protected ?
