This is my first side imaging/down imaging unit and I’m still learning to use it but I love it so far. With the basic, $50, single beam fishfinder I wasn’t able to catch any fish and now I know why – you need to find structure in order to find fish. I haven’t used side image much so far I’m mostly in down imaging mode but I can see a big difference already. You need to get a Navionics card, the preloaded map is not very useful but I guess that’s expected in this price range. All in all – a great fishfinder.

I’ve only used it twice but it has exceeded my expectations so far. The images are crisp and the GPS is accurate. I’m using Lakemaster Plus maps, I highly recommend them, they are much better than pre-loaded maps. The unit even has a setting for ice fishing but I’m not going to be able to use it here in Florida.

I bought this unit as a replacement for a black-and-white Lowrance. What a difference! The target separation so much better than my previous fishfinder. I can see the screen clearly even when it’s sunny. When installing make sure there is at least 15 inches distance between the propeller and the transducer, otherwise you may end up with interference.

Unfortunately this unit didn’t live up to my expectations. The graph produces, nice, sharp images but what I don’t like is that the refresh rate. It’s not able to keep up with the boat at 20mph or higher. Another annoying thing about it is that I can’t zoom-in when in split screen mode (chart/sonar), it works in sonar view only. It’s a decent fishfinder especially considering the price but it does have its drawbacks.

I really like this unit after using it for a few weeks. The screen is big and bright (they really need to get rid of those large digits on the side, they take up too much space). The images are crisp and very readable, it’s seems to be spot-on when it comes to locating fish. Make sure you get a Navionics and Lakemaster chip for your area, the preloaded maps are useless.

I’ve had my doubts before buying this unit. I’ve never used a side imaging fishfinder before and I’ve heard they difficult to read. It turns out this unit is very user friendly and easy to use. I’ve been on the water with it only 4 times but I feel like I have a good handle on the side imaging part. Finding structure is so much easier with side imaging.

I purchased this unit yesterday along with the lake master sd card. When I put the lake master sd card in, it didn’t want to go in straight so I turned it over and it wouldn’t even start to go in, so I turned it back over and gently pushed it in as straight as I could and it got stuck. I tried using tweezers to pull it out with no luck. So I tried a small screwdriver and the card started breaking apart. Ugh!! I called customer service and was ask to ship the unit to Humminbird. They were nice and the hold time wasn’t that long. They told me about a 4 to 5 day turn around once they receive the unit. Cost me $40 to ship it with insurance. Really sucks that I spent $900 yesterday and today I’m having to send unit in. I hope they can fix it and will replace the lake master card. I might have ought to stuck with lowrance. If they they don’t I’ll never buy one of their products again.

Got a gift of Helix 7 SI/GPS. I like the way the unit looks with a big bright display. It took ALOT of work to get it to be as efficient as my old Lowrance X135 and I’m still not sure…I use a drop shot and vertical techniques most of the time. I’ve had the unit for almost three months and I just figured out how to adjust it so I could see my drop shot fall to the fish or structure and it is still not consistent. Sometimes the display is pixelated and does not seem to be able to keep up with the data forming the display…This happens even when the boat is still. The alarms do not work properly…especially the fish alarms and symbols. I’ve owned a Lowrance HDS 5 and 7 and this unit acts just like they did. It is a different kind of view than the older units and it takes time to get used to it. There is no ping speed adjustment. I called Humminbird and they kept saying adjust ping speed and sensitivity. Even updating the software did not give me the features they said should be present. Their customer service is not run by fishermen…only people reading the manual and using data they’ve heard before. I’m sending the unit back to Humminbird so they can check it out to see if it is defective. I was assured that the unit would not be tested on the water…but they have ways of seeing if it is functioning correctly. The unit was about 600 dollars new. It should be able to outperform any expectation from a person who is used to an old x135. I’ll keep you updated on the outcome of this little adventure…

This time I did my research before buying, and it led me to the Helix 7 SI. Out of the box, I was pleased with it. Humminbird has designed a unit that’s very easy to use. The buttons are simple and easy to learn, and the screen is impressive with it’s clarity and bright colors. I’m happy that I forked over a little more money to get the bigger screen. Mounting was a breeze. My old fish finder’s down-imaging isn’t nearly as good, but I’m thinking about installing it along the side of my boat. For now, I’m still putting the Helix 7 through its paces. And so far, so good.
