If you are deciding between the iCOTEC Hellion+ and the iCOTEC 350+, the short answer is simple: both are current iCOTEC callers, but they fit different buyers.
The Hellion+ is the better pick if you want a much larger sound library, far more sound capacity, and a better remote interface. The 350+ is the better pick if you want to spend less, keep things simple, and do not need more than 30 sounds loaded at one time.


Quick verdict
- Pick the Hellion+ if you want a bigger preloaded library, much more sound capacity, and a display remote that is easier to live with.
- Pick the 350+ if you want the cheaper current iCOTEC option and 30 sound slots are enough for the way you hunt.
- Do not choose based on remote range alone, because both are listed with 300-yard no-line-of-sight RF remote control.
The cleanest way to think about this comparison is simple: Hellion+ buys you library capacity and remote usability. The 350+ buys you price efficiency and simplicity.

The biggest difference is not range
A lot of buyers assume the more expensive model must have more remote range. That is not the case here.
Both the Hellion+ and 350+ are listed with 300-yard no-line-of-sight remote control. So if range is your only reason for spending more, the Hellion+ is probably not the right upgrade.
The real reasons to move up are:
- more included sounds
- much higher total sound capacity
- easier remote navigation
- favorites and category-based sound access
- less dependence on memorizing numbered sound slots
Why the Hellion+ costs more
1. It gives you a much bigger sound library
The Hellion+ comes with 165 sounds. The 350+ comes with 30 professional sounds.
That is a major real-world difference. If you want a larger ready-to-use sound selection without swapping files around as often, the Hellion+ has the clear edge.
2. It holds far more sounds overall
This is one of the strongest reasons to choose the Hellion+.
The Hellion+ is listed to store up to 2,000 sounds on the included 32GB SD card. The 350+ is listed as holding 30 sounds at a time on a removable SD card.
If you like keeping lots of options available, these two callers are not in the same class.
3. The remote is easier to live with
The Hellion+ uses the GCX+ remote, and that matters.
Based on current iCOTEC materials, the GCX+ gives you:
- a large display
- sound categories
- day and night display options
- favorites banks
- separate play and pause control for two sounds
The 350+ remote is simpler. That can be a good thing if you want straightforward controls, but it is not as easy for managing a bigger library.
4. It makes more sense for buyers who want less friction
If you do not want to remember which number maps to which sound, the Hellion+ is easier to justify.
That is really the value case. You are not just paying for more sounds. You are paying for a system that is easier to browse and manage.

Why the 350+ still makes a lot of sense
1. It is the lower-cost entry into this comparison
The Hellion+ sits above the 350+ as the pricier step-up option in this part of the lineup.
That gap matters.
If you do not need a huge sound library or a display remote, the 350+ keeps more money in your pocket while still covering the core job.
2. It keeps the main platform features that most buyers care about
The 350+ is not a stripped-down dead end.
It still gives you:
- Bluetooth support
- 300-yard no-line-of-sight RF remote control
- two-sound playback
- programmable sound use
- tripod mountability
- 2-year warranty
That is why it remains a relevant buy for budget-focused hunters.
3. It is simpler to operate
Not every buyer wants a more involved remote or a giant sound bank.
Some buyers just want to load a practical set of sounds and hunt. For that person, the 350+ can be the better fit.
4. Its remote battery setup is simpler
The Hellion+ remote uses 4 AA batteries. The 350+ remote uses 1 A23 battery.
That does not decide the whole comparison, but it is one more point in favor of the 350+ if you want a simpler remote setup.
Sound capacity is the deal-breaker feature for many buyers
If you only remember one thing from this comparison, make it this:
- Hellion+: up to 2,000 sounds stored on the included SD card
- 350+: 30 sounds at a time on its removable SD card
For some hunters, 30 sounds is plenty. For others, it is a hard limit.
If you already know you like having a wide sound library available, the Hellion+ is easier to recommend.
If you run a smaller, consistent sound set and do not care about huge capacity, the 350+ may be all you need.
Remote usability matters more than spec shoppers think
This is where many buyers either save money or waste it.
If you are fine with a simpler numbered remote, the 350+ does the job.
If you want:
- category-based browsing
- easier sound selection in low light
- favorites lists
- a more informative screen
then the Hellion+ has the better case.
That does not mean everyone needs the GCX+ remote. It means buyers who care about easier navigation will notice the difference.
Bluetooth is shared, but it is not the same as RF remote range
Both models support Bluetooth, but Bluetooth should not be confused with the long-range RF remote claim.
The 300-yard control claim refers to the RF remote system.
Bluetooth is the shorter-range phone connection. For the 350+, iCOTEC also gives more specific Bluetooth guidance, noting up to 100 yards with better results when the caller has direct line of sight and is raised off the ground.
So yes, both have Bluetooth. No, that does not make them equal in sound capacity or remote usability.
Battery differences
Both callers require 4 AA batteries in the caller itself.
The remote setup is different:
- Hellion+ remote: 4 AA batteries
- 350+ remote: 1 A23 battery
The Hellion+ product information also includes specific battery guidance for the caller and remote. One important detail is that iCOTEC advises against lithium AA batteries in the GCX+ remote.
That is worth knowing if you already have a battery routine you use in other gear.
Pick the Hellion+ if
- you want a much larger preloaded sound library
- you want up to 2,000 sounds available instead of 30 at a time
- you want a display remote with categories and favorites
- you prefer easier navigation over simple keypad controls
- you do not mind paying more for convenience and flexibility
Pick the 350+ if
- you want to spend less
- you are fine with 30 sounds at a time
- you prefer a simpler remote
- you still want Bluetooth, two-sound playback, and 300-yard RF remote control
- you want the better value if your sound needs are basic

Which one is the better value?
For most buyers, value comes down to whether you will actually use the Hellion+ upgrades.
The Hellion+ is the better value if you know you want:
- more included sounds
- a much larger total sound bank
- a better remote interface
- easier sound organization
The 350+ is the better value if you mostly care about:
- lower price
- simple controls
- core calling features
- keeping a smaller working sound set
That is why neither model makes the other obsolete. They are aimed at different buyers.
Final recommendation
Choose the iCOTEC Hellion+ if you want a more feature-rich caller with a much larger library, far more storage, and a better remote experience every time you use it.
Choose the iCOTEC 350+ if you want a simpler and less expensive caller that still keeps the core features most buyers actually care about.
If you are torn, use this rule: buy the Hellion+ for sound capacity and remote usability, and buy the 350+ for price and simplicity.
