sidescan transducers

[randlemanboater]

I hadn't even thought about the motor being in the way of a sidescan transducer on the transom, it does seem like it one side would get blocked.

In am trying to figure out if the working unit on my "new" boat supports sidescan. It is a Garmin 741xs and on the unit itself it has the option for sidescan, but everything I can find on the internet says the 741xs doesn't support sidescan.

Anyone know about that at all?

I have a Garmin GPSMAP 7608xsv. It is capable of sidescan, however we never use it. We walleye fish here in Lake Erie's central basin for fish suspended in the water column. I find that traditional CHIRP sonar is all we need. Had a transom mount duser and wasn't happy with the results. Switched to a thru-hull ducer, (Yeah, I spent the money) but the difference was incredible. Just something to consider. I tried to save a few bucks with the transom mount and ended up spending more.

The existing traditional FF/Gps has a really good thru hull and works great even running @ 30 mph. Trolling in the canyon I was reading bottom @ 1200ft. Tho I know the sidescan would be great with a thru hull on the centerline, its just alot of money for a "secondary" FF. Since I already have a really good down sonar, I figure I should get sidescan to gain some added benefit. I know they don't go deep but it seems it will be a great help finding schools of bait off to the side and finding debris fields next to wrecks in under 100ft.
With the current deals I will basically get a transom xducer for $50 so I might as well try it for a season before dropping $700 on a thru Hull


On my V20 (just sold!) I had a shoot-thru-hull epoxied to the inside hull and it was far better than any transom mounted xducer I ever had.

741xs "supports" sidescan if you have separate GCV10 scanning sonar module connected. (after 5 days of research I'm becoming an expert on the Garmin product line....)

Ah, thanks.

That explains why I couldn't find a sidescan transducer that would hook to the unit.

Skunk...I am running the 94SV...transducer is mounted on stern near OB. At speed I can see depth, but not details.
I am not sure if I can improve on this...I do know I am not likely to drill more holes.
I dont fish at 30 mph, so I have not worried about it.

Bottom line; very pleased with the unit. The default maps are very good IMO, and the side scan and clear VU are incredible. I dont see any interference where I have the transducer mounted...at least not at fishing/trolling speeds...or anchored (tog) fishing.

Check into running dual transom mount transducers. I know hummingbird had a cable that allowed you to run one mounted outboard of the hull on either side, and they plugged into a y cable that plugged into the head unit. This way dual outboards wasn't an issue.

unfortunately, these sidescan transducers cost $600 a piece for a transom mount when its not included with a unit. Thru hulls are $700. They sell a 2 xducer thru hull kit for big boats and people who don't blink at cost....So buying an extra one is too painful.

I just bought the Garmin 94sv w/transom mount xducer at West Marine. They have triple reward points today so that saves me over $100.

Between the box and a ducer it would cost me over a grand, guess I will stick with looking down only.

Tranducers are part of a secret satanic world domination conspiracy, brought to you by the same elite controllers that have you buy "submersible" trailer lights, boat horns, and non stainless stainless steel. They funded their original operation with money generated by the sales of parts made of "Chrome plated Zamak".
