The Humminbird-Helix 5 SI 409640-1 is a combo unit with both sonar imaging and a GPS unit. It is an old model that was released back in 2015, as such it lacks CHIRP capabilities, which is the latest invention in the world of sonar.

That said, it is still a popular model and a powerful unit for that matter because it has three types of sonar imaging capabilities namely Side imaging, DualBeam, and Down Imaging. The sonar imaging is for fish finding and providing depth views.

Sonar Capabilities

Side imaging makes this unit unique. With the side imaging, you will get a below side view of the boat at 180 degrees. It is very helpful when fishing in inshore saltwater and lake fishing in water depths of not more than 100 feet.

While down imaging and DualBeam sonar show what is below your vessel and it is ideal for fishing in water depths that are about 1500 feet. It features the traditional 2D sonar (not CHIRP sonar) but the more advanced DualBeam plus sonar which uses two beams and both beams can be effected simultaneously.

Additionally, the sonar will give you other details and features to help you in locating fish and navigating your way through the waters. They include Fish Alarm, Real Time Sonar, Selective Fish ID, Bottom Lock, SwitchFire, among others.

The depth capacity for the Side Imaging and Down Imaging is 100 feet. You can also use this unit to record sonar recordings but on a microSD card if you need to view it later.

The unit comes with a transducer that supports the three sonars. It has a transom mount and a 20ft cable. The transducer has a temperature sensor.

Navigation Capabilities

The included GPS is a powerful unit that has UniMap cartography and chart plotting. You can mark up to 2,500 waypoints, 50 tracks, create up to 45 routes, noteworthy it is almost impossible to exhaust this capacity. The GPS will give you accurate coordinates of your location and any coordinate of a point of interest. It also calculates the boat speed.

Other Features and Benefits

This unit is easy to operate with the provided control buttons. It has a color screen that is 5 inches diagonally with backlight features. For memory storage, it has a microSD card slot. You have an option to choose other languages apart from English too.

Criteria for Choosing Expensive GPS Combos

When it comes to choosing the best combo fishfinder GPS combo priced under 1,000, the best thing you can do is keep your mind open. But even then, you also want to stick to the following buying criteria.

The Size of the Display Screen

This might seem like a minor issue until you’re out there in the wilderness and notice that your screen is crowded with all manner of details. That would make it difficult to grasp the data that matters.

As such, user experience is a top priority when choosing a screen. Ideally, you want it to be colored and to also be backlit so it’s easy to view even under the glare of sunlight. Besides those two factors, you’re better off going for a screen size that’s neither too large nor too small.

Anything larger than 7-inches might be too large especially if you’re looking for a portable combo. Likewise, anything smaller than 2-inches might be too small to view comfortably.


As we have mentioned, the technology behind these devices has come a long way. Indeed, the main thing that makes these gadgets worth investing in is their technological advancements.

For instance, the presence of waypoint maps is a big plus for anyone looking for quality. Waypoint maps make it easy to mark locations so you have an easier time accessing the next time. For instance, if you’re a keen angler, you’ll want to mark the docks, stumps, and even brush piles.


Chances are that you have come across the name CHIRP severally in our reviews and you’re wondering what the hell that is. Well, to put it simply, CHIRP stands for Compressed High-Intensity Radiated Pulse. This is a game-changing technology used in sonar and radar equipment.

Modern fishfinder combo should have such features. One thing you need to know is that CHIRP technology does a better job of resolving images compared to your traditional sonar.

The pulse compression is the one that makes these devices superior particularly owing to the fact that it converts normal frequency into a narrow pulse for enhanced amplitude. The narrower the pulse gets, the better the resolution and also the better the signal to noise ratio gets.

So, once again, while traditional sonar equipment is cheaper, the CHIRP sonar machines are better – any day!

Is The Machine Water-Resistant?

Since these devices are meant to be used in areas with water, it is important that they are designed to be water resistant. Much as we may plan adequately for the trips ahead, accidents happen.

You might easily splash water onto your device. There have even been cases of the combos falling into the water and getting submerged.

The unfortunate truth is that not all fishfinder GPS combos out there are up to the task. That’s why it’s important to insist on this feature before committing your hard-earned cash.

When it comes to choosing a water-resistant device, we’d suggest going for something rated as either IPX6 or IPX7. So, what do those two ratings mean?

IPX6 Water Resistant Combo

A unit marked as IPX6 water resistant is one that can comfortably withstand the impact of a water jet with a 12.5mm nozzle. In fact, such a machine can withstand most accidental splashes as long as they don’t exceed 3 minutes in duration.

Much as IPX6 devices are well protected, they may not survive accidental falls and immersions into the water. Therefore, they need to be used with a lot of caution.

IPX7 Combo

This is our top recommended water resistance rating. With this kind of gear, you are assured that it can fall into the water and you still retrieve it while it’s working.

But there are limits. Even the best made IPX7 GPS fishfinder combo can only last underwater for up to 30 minutes. Also, as far as depth is concerned, even the best made of all units in this category cannot last prolonged immersions beyond 3.2 feet deep.

So, in terms of quality, we’d recommend the IPX7 units. But if you’re on a tight budget and are willing to invest in a good mounting for your combo, you’d still be okay with an IPX6 device.

The Frequency Level

When it comes to choosing the right frequency for your gadget, you need to consider your style of fishing. Do you fish in deep water surfaces? The name frequency, in this case, refers to the ultrasound frequency generated by the system.

A low-frequency fishfinder (e.g. 50kHz) is ideal for conducting searches in deep water surfaces. But you also need higher-frequency (e.g. 200kHz) levels if the search depth is shallow and you want to really zero in on the fish.

At the same time, it’s worth remembering that multi-frequency fishfinders exist. These enable you to use different frequencies as you might please. For instance, you can use a low-frequency beam to get the general location of the fish. At the same time, you can switch to a high-frequency beam when you’re operating directly above your target.

Which One Is The Best?

We have a thing for the Garmin-Striker 7SV 010-01809-00 Transducer, GPS. It has a generously large screen which though makes it less portable provides you with a wide field of view. This device is rated as an IPX7 meaning you can use it without worrying about it accidentally falling into the water.

It also packs a chirp sonar which provides you with awesome target separation and crisp fish arches.

Final Thoughts

A 2-in-1 fishing gear such as the fishfinder GPS combo is a one of a kind in helping you get a better time while searching for fish. But since not all combos out there are worth their weight in gold, it always makes sense to widen your search. Indeed, it’s our hope that the reviews and buying guide above have come in handy in that quest.
