Deeper Range Extender Full Kit
Full Kit
A tidy way to extend your Deeper connection and organise a bait-boat sonar setup. Just remember: extra Wi-Fi reach isn't extra sonar power, and the advertised 200 m isn't a promise for every swim.
- Advertised Wi-Fi connection range of up to 200 m / 656 ft.
- Range extender battery life of up to 14 hours, with a full charge taking 3 hours.
- Phone clip adjusts across a stated width of 5–8.5 cm.
- Bait-boat sonar holder has an adjustable length of 18–28 cm.
Make sure it’s the right one. This is an accessory kit built around the range extender, phone/range extender holder and bait-boat sonar holder—not a standalone fish finder. We've not tested it on the bank.

Who it suits
Is it right for you?
Great for
- Existing Deeper users scouting with a compatible bait boat. It brings extra connection reach and mounting accessories together, rather than leaving you to sort each bit separately.
- Anglers investigating features farther from the bank. The advertised reach offers more scope to explore depth changes where your existing connection becomes the limiting factor.
Maybe skip if
- Margin anglers and short-range sonar users. If your current connection already covers your fishing, this adds charging and setup without much practical gain.
- Anyone wanting an all-in-one fish finder. This is supporting kit, not the sonar itself, and you still need a suitable phone, compatible sonar and boat arrangement.
The lowdown
Introducing the Deeper Range Extender Full Kit
A tidy way to extend your Deeper connection and organise a bait-boat sonar setup. Just remember: extra Wi-Fi reach isn't extra sonar power, and the advertised 200 m isn't a promise for every swim.
- Advertised Wi-Fi connection range of up to 200 m / 656 ft.
- Range extender battery life of up to 14 hours, with a full charge taking 3 hours.
- Phone clip adjusts across a stated width of 5–8.5 cm.
- Bait-boat sonar holder has an adjustable length of 18–28 cm.
Quick verdict
Handy reach, provided your setup needs it
If you already use a compatible Deeper with a bait boat, this is a sensible way to tackle connection reach and mounting together. The adjustable sonar holder and combined phone/extender holder make it more useful than a signal accessory on its own.
It's less convincing for margin work or occasional short-range scanning. Check compatibility before buying, treat 200 m as an upper limit rather than a guarantee, and remember you've got another battery to keep topped up.

The stated materials and adjustable holders suggest a practical package, but durability and weather resistance haven't been verified on the bank.
Up to 200 m of advertised reach and 14 hours of battery life offer useful scope, although real connection performance remains untested here.
It can support better feature scouting, but its effect on catches is indirect and still depends on location, interpretation and presentation.
Bundled holders help organise the setup, offset by compatibility checks, mounting and another charging job.
The package has a sensible purpose if you need both reach and holders, but without a confirmed price this is a provisional judgement.

The full rundown
Everything you'll want to know about the Deeper Range Extender Full Kit
If you use a Deeper on a bait boat, you'll know why connection reach matters. You can have a promising bit of water in front of you, but a sonar picture is only useful while it keeps reaching your phone. The Deeper Range Extender Full Kit is aimed at that part of the job. It pairs the extender with mounting accessories for your phone and sonar, giving you a more organised starting point for scouting farther out. It's supporting kit, though, not a new fish finder.
The headline is an advertised Wi-Fi connection range of up to 200 m. That's useful scope on bigger waters, particularly when you're trying to follow a depth change rather than just check the margins. But keep the words 'up to' firmly in mind, mate. Positioning, obstructions and conditions can affect a wireless link. We've not tested this kit on the bank, so we're not claiming it'll hold a flawless connection at the far end of every lake. Think extra potential reach, not a guaranteed distance.
There's an important distinction here: extending the connection doesn't improve the sonar's own ability to separate targets or read the bottom. You're helping the information get back to you, not turning the unit into a different sonar. That's still worthwhile if connection reach is what's holding your setup back. It just means the sensible reason to buy is more usable coverage with your existing compatible kit. Buying it because you expect clearer fish identification or magical carp-finding powers would leave you a bit gutted.
The Full Kit also tackles the less glamorous business of holding everything in place. You get a phone/range extender holder, plus a bait-boat sonar holder with an adjustable length of 18–28 cm. That adjustment gives you some room to work with, but it isn't proof of a universal fit. Have a proper look at your boat's mounting arrangement before spending. You want the sonar positioned as its instructions require, with nothing fouling the boat's moving parts or getting in the way when you launch and retrieve it.
Phone fit deserves the same quick check. The clip's stated width range is 5–8.5 cm, so measure your handset with its usual case on rather than assuming it'll squeeze in. A chunky protective case can make the difference between bob on and a frustrating bit of faff. The holder uses aluminium alloy, ABS, stainless steel and silicone, while the extender has an ABS enclosure with a metal insert. Those details tell you what you're buying, but they don't prove long-term durability or mean you can dunk the electrics.
For session planning, the extender's stated battery life is up to 14 hours, with a full charge taking three hours. That's a useful allowance for a day's fishing, especially if you're doing a few deliberate scouting runs rather than constantly circling the swim. Remember that your phone, sonar and boat have their own batteries, though. The whole arrangement is only as ready as its least-charged bit. Charging everything before leaving home is a much better plan than discovering one flat device just as the light starts looking proper carpy.
On the water, keep the job simple. Pick a feature you want to understand, make a controlled pass, then compare what you're seeing with another pass along a similar route. Depth changes are useful information; a single intriguing mark isn't a reason to empty the bait bucket. Once you've chosen a spot, think about how you'll present a rig there and manage the line between rod and lead. Extra reach doesn't remove snags, improve line lay or make fishing beyond sensible control a clever idea.
That's where this kit makes most sense: an existing Deeper user, a suitable bait boat, permission to use it and a genuine need for more connection reach. If you mostly fish short, it could be another gadget to charge for very little gain. Check the fishery's boat and sonar rules, confirm compatibility and stay within the stated 0°C to 40°C operating range. Get those basics sorted and the appeal is straightforward—a practical accessory package for exploring your swim, not a shortcut to a screaming take.

Our take
Extend the connection, not your expectations
The useful bit is staying connected while you investigate a spot farther out. It doesn't upgrade the sonar itself or make every fish-shaped mark a carp.
Use the extra reach to understand depth changes and repeat a sensible route—not to spend bite-time driving a boat all over the lake.
The kit
Closer look: connection and mounting in one package
The range extender is the main attraction: a 91 g unit measuring 15.1 × 4.6 × 2.25 cm, with an advertised Wi-Fi reach of up to 200 m. Its job is connection support. Don't confuse that distance with sonar scanning depth, bait-boat control range or a recommendation for how far out you should fish.
The accompanying holders are the practical side of the Full Kit. The phone/extender holder weighs 73 g, while the bait-boat sonar holder offers 18–28 cm of length adjustment. Before launching, check that everything is secure and that the mounting position follows the relevant instructions. A tidy-looking arrangement on dry land still needs checking afloat close to the bank.
Worth knowing. No waterproof rating is confirmed here. An ABS enclosure alone doesn't tell you what exposure the extender can handle, so follow Deeper's care instructions rather than treating it like the floating sonar.
Your fishing
Who it suits: useful for a specific job
This is most appealing when you already have a compatible sonar and your bait-boat scouting is being limited by the connection. Sorting reach and holders in one purchase can be dead handy. Confirm support for your exact Deeper model and the mounting requirements first; the brand name alone isn't enough to settle compatibility.
It's harder to justify for an angler who only checks near-bank shelves or uses sonar a handful of times a year. More equipment means more preparation, and the holders may add little if you've already got a satisfactory arrangement. We haven't pinned value to a current price, so compare the full package with what you actually need—not just the longest distance on the box.
Give neighbouring anglers room, too. A boat being able to reach a patch of water doesn't make it your spot. Keep runs controlled, avoid crossing other lines and do the exploring before the bite-time you're trying to make the most of. Better information is useful; endless disturbance is a different matter.
Quick answers
FAQs in full: reach, charging and fit
Will it definitely work at 200 m? No—the advertised figure is an upper limit, not an assurance for your particular swim. Follow the setup instructions and check the connection close in before extending your route. Also keep the boat within its own safe operating limits; a working sonar connection doesn't tell you how much control range or battery reserve the boat has left.
How long will it run? Deeper states up to 14 hours for the extender, with three hours for a full charge. Plan around every device in the setup, not just that headline figure. If you're on a longer session, sort a suitable charging plan before you leave rather than gambling on everything lasting until pack-up.
Will everything fit? The stated phone clip range is 5–8.5 cm, and the sonar holder adjusts from 18–28 cm. Those measurements help, but they don't settle case shape, boat attachment or exact sonar compatibility. Check all three before ordering. A few minutes with a tape measure and the fitting instructions can save a proper headache.
