Helix 7 MDI G3N question – for use on ice…

I’m thinking of picking up a 7 MDI G3N, to use at the bow of my boat in the summer (am set up for networking and have the MDI ducer on the trolling motor). Also, want to rig it up for ice use this winter (and on my row-boat at home – am building on a non-motorized lake). Thinking about rigging up a pelican case to carry the control head, battery, etc. that I can use both on the ice and in my row-boat. Then, transfer the control head to a RAM mount in the big boat when used there. Question is… can I rig up the transom-mount transducer that comes in the package for use on the ice?? I’m thinking I’d need a rigid pole or plate that could be stuck into the ice-hole and hold the ducer flat… Used an old Clearwater Classic years ago and that ducer was mounted on a pole, rigged onto a Genz box… Anyone ever rig up a transom ducer for use on the ice?? Any reason why it wouldn’t work?

that will work but there may be a cheaper easier idea. Haven’t tried it but saw pictures of guys using a rubber band between the ducer and the ducer cable. This way it was level and they could lower it down a hole.

More expensive option is to get the 1521 ducer for ice fishing. last week it as $80 at Marine General.

yes, I thought about getting the ice transducer, which allows for the dual CHIRP but I couldn’t find anything that indicated it allowed for the Mega Down Imaging??

Someone posted this a couple of years ago. I did the same last year. I bought a Vexilar foam float and added it to control how deep it goes to get under the ice. It worked good.

Glen, I maybe wrong but I believe that both down and side imaging really need to be moving to provide mega imaging.

Their sonar cone patterns are very thin slices and the images are a composite of those slices.

2D chirp is the only stationary real time imaging available. So, no matter which transducer you hang on the head unit. The 2D images are the only accurate real time images.

Hope that makes sense to you, fish on…..

It doesn’t and it shouldn’t. djshannon is correct. It’s the difference between a very small slice vs a cone for coverage below.

If your talking looking at structure
Yes it will looked stretched sitting still. But fish are swimming and still show up very easily sitting completely still on the mega side imaging. I would actually say the detail of the fish gets better at a absolute standstill. Here’s a few sturge and paddlefish I’ve graphed while sitting completely still on spotlock.
