Who it suits
Is it right for you?
Great for
- Anglers fishing unfamiliar venues. You can map depths, find changes in the lakebed and make a more informed choice of swim and spot.
- Predator and feature-focused anglers. The frequency range, tight beam and fine target separation are useful when searching for structure and likely holding areas.
Maybe skip if
- Casual anglers on small, familiar pools. If you already know every shelf and margin, a fish finder may be more faff and expense than you need.
- Anyone wanting completely hands-off fishing. You still need to understand what the display is showing and turn that information into a sensible plan.
The lowdown
Introducing the Deeper CHIRP+ 2
A proper bit of kit for mapping depths, locating features and checking what’s going on beneath the surface — without lugging a boat around.
- Three CHIRP frequencies: 100, 240 and 675 kHz.
- Depth range from 15 cm to 100 m, with target separation down to 1 cm.

Quick verdict
Verdict
The Deeper CHIRP+ 2 is a cracking fish-finding tool for anglers who want a clearer picture of the lakebed, depth changes and likely holding areas from the bank. Its three CHIRP frequencies give you a useful spread, from broad water searching to properly tight detail over a chosen spot.
It’s not magic and it won’t replace watercraft, but it can save a fair bit of guesswork. If you fish new venues, like mapping swims or want to find a clean area before clipping up, this is a very handy bit of kit. The main sting is that it’s specialist tackle, so casual anglers may struggle to justify the outlay.

The ABS enclosure, titanium inserts, rechargeable battery and included protective accessories make it feel properly equipped.
Three CHIRP frequencies, up to 15 scans per second and a 15 cm to 100 m depth range give it strong versatility.
It can help you find better depth, features and repeatable spots, though it still depends on good angling judgement.
Casting and wireless connection are straightforward, but interpreting sonar and building useful maps takes a bit of learning.
It offers a lot for dedicated feature-finders, but occasional anglers may find the price bracket hard to justify.

The full rundown
Everything you'll want to know about the Deeper CHIRP+ 2
There’s a lot to like about a bit of kit that helps you stop fishing blind. The Deeper CHIRP+ 2 is a castable sonar unit that links to your device over Wi‑Fi, giving you a look at depth, features and what’s happening below the surface. Handy stuff when the water’s new or the fish are keeping their cards close to their chest.
It comes in a Desert Sand finish, with an ABS enclosure and titanium inserts. That gives it a practical, purposeful feel rather than looking like a toy you’d chuck in the tackle box and forget about. It’s compact enough to carry without much bother, and the included neoprene pouch is a nice touch for keeping it protected between swims.
The clever bit is the three CHIRP frequencies: 100, 240 and 675 kHz. In plain English, that gives you different ways to scan. The lower frequency covers more water, while the higher frequency is better suited to picking out detail over a more focused area. That flexibility is the main reason this model is more interesting than a basic sonar gadget.
The beam angles are 47°, 20° and 7°, matching that spread of searching and detail. A wide beam can help you get a general feel for what’s in front of you. The tight 7° beam is more surgical, which is bob on when you’ve found a likely bar, shelf or drop-off and want to inspect it properly.
Target separation goes down to 1 cm, while the depth range runs from 15 cm to 100 m. Most UK carp and coarse anglers won’t be anywhere near the deeper end, of course, but the important bit is the ability to see changes in depth and structure. Those little transitions can be the difference between chucking at a random patch and putting a rig where it might actually get noticed.
The unit can scan at up to 15 times per second, so you get a fairly lively picture as it moves across the water. It also has an integrated temperature sensor with 0.2°C accuracy. Temperature alone won’t tell you where the fish are having their breakfast, but it can add another useful clue when you’re comparing bays, margins or different layers of water.
GPS is another big part of the appeal. With the right app setup, you can build a map of the water, mark useful areas and return to the same spots with a bit more confidence. That’s especially useful when you’re clipping up for a long chuck, checking a new swim or trying to understand how a venue changes across the seasons.
Connection range is quoted at up to 120 m, and the battery runs for up to 9 hours with GPS on or 15 hours with GPS off. That’s plenty for a proper session if you manage your settings sensibly. It charges in roughly two hours, too. In the box you get the sonar, USB cable, neoprene pouch, two attachment bolts, quick guide, safety regulations and a night-fishing cover. So, pretty much everything needed to get set up without a load of extra faff.

Our take
The big angle
This is less about staring at pretty fish icons and more about building a picture of what’s under your bait. Find the depth, locate a crease or drop-off, check the lakebed and mark useful areas for later.
For predator anglers, the narrow 7° beam and fine target separation can help when you’re picking apart a likely feature. For carp and coarse anglers, the real appeal is repeatable mapping from the bank, especially when the water is new or the margins are doing nothing.
What you’re buying
A castable sonar unit with plenty of detail
The CHIRP+ 2 is built around three frequencies and three beam angles. Use the wider spread to search, then switch your attention to the tighter beam when a feature looks worth a closer look. That suits a proper watercraft-led approach: scan, think, then fish the spot rather than chucking around aimlessly.
The ABS enclosure has titanium inserts, and the unit includes two attachment bolts. There’s also a night-fishing cover, which is useful when you’re trying to keep the display and equipment setup sensible after dark. The integrated temperature sensor adds another little piece of information to your swim picture.
Worth knowing. The best results come from combining the sonar picture with what you can see and feel yourself. A clean return or depth change is a clue, not a guaranteed bite. Use it to guide your rigs, not to switch your brain off.
Where it earns its keep
Useful on new water and feature-led sessions
If you regularly fish unfamiliar lakes, this makes a lot of sense. You can work out where the bottom drops away, find flatter areas and build a map instead of relying on guesswork. That can be especially useful when the fish aren’t showing and every cast needs a bit more thought.
Predator anglers get the benefit of the focused beam and fine target separation when searching around structure or likely baitfish areas. Carp anglers can use it to find depth changes, bars, silt-to-gravel transitions and spots that are worth clipping up to. Coarse anglers might appreciate it when exploring a large water or locating a sensible depth before settling in.
Worth knowing. GPS use reduces the quoted battery life to up to 9 hours, compared with up to 15 hours with GPS switched off. For a long mapping session, carry your charging plan and don’t leave the unit doing more work than needed.
The practical stuff
A few things to know before you buy
The CHIRP+ 2 connects over Wi‑Fi, with a stable range quoted up to 120 m. That gives you useful room to scan a swim or map a chuck, but your own casting setup still needs to be safe and sensible. Don’t go swinging expensive kit around with a dodgy knot or worn leader.
The operating temperature range is −20°C to 40°C, so it’s built for a broad spread of conditions. The rechargeable 3.8 V, 1300 mAh Li‑Ion battery takes approximately two hours to charge fully. The box includes the USB cable, pouch, bolts and night-fishing cover, so there’s no obvious need for a pile of extras just to get started.
Worth knowing. The unit shows you information; it doesn’t choose the swim, tie the rig or make the fish feed. Read the depth changes, watch the water and use the clues properly. That’s where the real edge comes from.

The stuff you’d ask your mate on the next peg. Straight answers, no waffle.
01Can the Deeper CHIRP+ 2 be used from the bank?
Can the Deeper CHIRP+ 2 be used from the bank?
Yes. It’s designed to be cast out and connected wirelessly, so you can scan water from the bank without needing a boat. Keep your casting tackle, knots and attachment point sensible, because this is still a fairly valuable bit of kit on the end of the line.
02What does the narrow 7° beam do?
What does the narrow 7° beam do?
It focuses the sonar into a tighter area, which is useful when you’re checking a specific feature or trying to get a more precise read on a chosen spot. The wider beams are better for searching more water quickly.
03How long does the battery take to charge?
How long does the battery take to charge?
A full charge takes approximately two hours. The quoted operating time is up to 9 hours with GPS switched on, or up to 15 hours with GPS off.
