I was wanting one for my boat as well especially for the front, since that is the place it would be more advantageous I believe. Maybe I'll sell my brand new Lowrance 5200c GPS unit and save a little more and then get me one of them Hummingbird ones.
Glad you like the new unit and hope it does well for you...

I did buy a ram mount for it so I can turn it to the front I can see it good enough to tell if theres something out of the ordenary (?) but ill have to get closer to get a good view of it but its great for just idleing around marking spots

I'd like to make a suggestion that I think will help you out. You can buy another cable to add length to the transducer cable and the power cables. You can also buy an additional mount for the front of your boat. That way you can use the display unit at either location. It's a lot more comfortable with the unit at the front of the boat when you are fishing and trying to look at the unit. Remember that the unit can be used in side scanning mode or 2 D regular depth finder mode.
Most guys use the Side Scanning mode while motoring around the lake looking for cover. They mark the cover while sitting in the drivers seat going in a very straight line and only going 3 to 4 mph. This works best and gives the best pictures of the bottom while in Side Scanning mode. Remember that you can view the side scanning mode screen along side the 2D Regular Depth Finder screen at the same time. When you see a stump or rock pile you simply freeze the screen for a second nd then move the screen cursor to the rock pile and push the mark button. This saves the rock pile as a GPS Waypoint which you can later navigate back to and fish. Unfreeze the screen and continue along the straight line until you finish your pass. Go back and move along another line parallel to the last line and offset by about 100 ft. You can map all the important spots on your lake and then record all those good looking spots as Way points.
Now after you have all your spots marked you can move to the front of the boat and fish. Just move the display unit up to the front of the boat and set the screen up to 2D mode and GPS map screen (split Screen Mode) and use the GPS screen to navigate to one of your way points. You should have a good minds eye view of the lay of the land around the waypoint or rock pile and be able to maneuver the boat right over the spot.
You can even run your older depth finder up on the front of the boat and use it to fish and just use the Humminbird SI unit to map the lake bottom.
NOTE: mounting the Humminbird SI transducer to the Trolling motor may not be the best place for side scanning operations. The side scanning transducer when used for side scanning must be mounted firmly in place and not moved easily. You have to be moving at around 4 mph to get the best results while scanning in Side Scanning mode. Since the trolling motor may rotate around that will make the side scanning part of the unit fail to operate right. IE you scene pictures will be blurry. Now you can use the Side scanning Sonars transducer on the trolling motor and then switch to 2 D mode and that will work great. But then you will have to look back to the back of the boat to see the screen unless you mount the screen up at the front of the boat with a second mount. You can wire both mounts to accept the control head or display unit. That will be the best way.
Some guys have two units and mount one at the front and one at the driver console.
Most people will mount the transducer on the back of the boats transom and away from any turbulent water flow. That's the key to getting good operations at high speed with the 2 D operations. SI operations won't work at high speeds. You must go slow to get the good SI pictures of the lake bottom on the screen.
I hope this information helps those that are thinking about buying one of these unit's or that have just purchased one.
Mounting the transducer in the right spot is very IMPORTANT. Critical in fact.
Any water turbulence or air bubbles will ruin the transducers ability to time the sound waves to the bottom and back correctly. Remember that sound travels faster though water than air and any air bubbles will screw up the timing of the sound waves to and from the bottom.

I had it sent into Humminbird once and they fixed it and shipped it back to me really quick. I was impressed with how well they took care of me. Now I have had this unit since 1985/86. I still use it for finding brush piles and drop offs and can hover right over a submerged tree using this thing.
I use to have to look back at the drivers console to see the thing while fishing off the front of the boat. And I had the transducer mounted at the back of the boat, 16 ft away from the front of the boat where I was sitting.
My neck use to get sore after a few hours looking back wards all day long.
That's when I saw how other's were mounting their unit up on the front of the boat. I didn't have the money to spend on a new unit so I had to make do with what I had. I was lucky that my electric power cable and the transducer cable was long enough to reach the front of the boat and drivers console. So I could move my unit around to both spots. All I had to do was figure out a way to mount the unit. Since it was an older model I could not buy another mounting system. I modified my mounting unit by putting Industrial Strength Velcro on the bottom of the mounting bracket. I added a stained, varnished 5/8" thick oak board to the front of my boat and to the center steering wheel console. I glued and stapled Velcro to both boards. Now I can easily move the display head to the front of the boat or to the steering console. Since my transducer is mounted permanently to the rear of my boat I had to buy another transducer. I chose the transducer for the trolling motor and use that one when I am up front fishing and using the trolling motor. I have to remove the plug for the back transducer and then plug in the front transducer but it's not that hard to do. I coil the transducer wires around my front navigation light and secure it in place with a Velcro tie. I just unplug the end of the cable for the front transducer and then plug in the transducer plug for the rear mounted transducer and then move the control head to the steering console and I am ready to speed across the lake.
They do make a control box where you can plug into the box both transducer plugs and then run only one cable from the box to the control head. This way all you have to do is move a toggle switch to switch from the front transducer to the read transducer. But they don't carry that box anymore so I am out of luck
But I ended up fishing in a small 90 acre to 200 acre lake(s) that were trolling motor only lakes for the last few years. So I kept the display unit mounted at the very front of the boat all the time and hooked up to the trolling motor transducer all the time. The only time I had to switch the location was when I went down to KY lake or up to Patoka Lake.
Now that my strip pit lakes have been opened to gas motors at idle speed I can use the rear transducer as I am driving the boat from the steering console while using the gas motor and then switch to the front transducer when I am fishing from the front of the boat.
All this is using a 2 D type transducer that only sees the area of the lake bottom directly under the trolling motor's transducer. That's only about a 4 ft diameter area of the lake bottom.
With a side scanning unit I'll be able to cover a swath of 240 ft of the lake as I motor around in a straight line at 4 mph. I would be able to map each of the lakes I fish easily. Since they vary in size from 90 acres to 210 acres it won't take very long to map them all. There are only three lakes that have good launch ramps. I can only launch my boat at the Concrete Launch ramps.
