Who it suits
Is it right for you?
Great for
- Coarse and match anglers exploring unfamiliar swims. It can show the depth and shape of the water before you settle on a line, which is handy when every inch of the swim matters.
- Bank anglers who want a portable fish-finding tool. The 60 g body slips into a carryall without eating space or turning a quick recce into a full expedition.
Maybe skip if
- Anglers wanting a highly detailed multi-beam picture. The START uses a single beam, so it won’t offer the same level of underwater detail as more advanced fish finders.
- Anyone planning long, all-day scanning sessions. The battery is rated for up to six hours, so heavy use could call for a recharge before the rods are off.

Quick verdict
A clever bit of kit for reading new water
The Deeper START gives you a simple way to scan a swim from the bank, helping you find depth changes, features and possible fish activity without lugging a boat or a mountain of kit.
It’s compact, light and easy to understand, though the single-beam sonar and six-hour maximum battery life mean it’s best viewed as a useful swim-finding tool rather than a full-blown fishery command centre.

The full rundown
Everything you'll want to know about the Deeper START Smart Fish Finder
There’s a lot to be said for knowing what’s under the float before you start feeding. Is there a bit of extra depth just beyond the near shelf? Does the far bank drop away? Is that lovely-looking margin actually ankle-deep? The Deeper START is built to help answer those questions from the bank, using a compact sonar unit and a phone or tablet.
This is the small, straightforward end of the Deeper range. The unit itself is only 60 g, so it won’t have you hauling a brick around in the carryall. It’s also compact, measuring 60 × 65 × 65 mm, which makes it dead handy for a quick recce before a session or for checking a few likely areas when the water looks a bit moody.
The START uses a single-beam sonar operating at 120 kHz. In plain English, it sends sound through the water and uses the return to build a picture of what’s down there. You’re looking for depth, changes in the bottom and fishy-looking signals. It won’t replace watercraft, but it can give your instincts a useful nudge in the right direction.
Its 40° beam angle is broad enough to cover a decent patch beneath the unit, while the stated scanning range runs from 0.5 m down to 50 m. Most coarse anglers won’t need anything close to that maximum depth, of course. The useful bit is being able to compare areas and spot a change from flat, featureless water.
That can be particularly useful on new commercial fisheries, canals and larger stillwaters. Cast it towards a likely line, bring it back steadily and you can start building a rough picture of the swim. You might find a deeper track, a shelf, a clear spot or a margin that’s shallower than it first appeared. Those little details can shape where you put the float, feeder or bait.
The wireless connection works over Wi-Fi, with a stated range of up to 50 m. That gives you room to position yourself sensibly on the bank while keeping an eye on the scan. You’ll need a compatible phone or tablet to make the most of it, so keep your device charged and protected from the usual mix of drizzle, bait and muddy fingers.
Battery life is rated at up to six hours. That’s plenty for mapping out a swim, checking a few spots and doing a bit of homework before fishing properly. If you’re planning to scan all day, though, you’ll need to manage that power carefully. There’s a USB cable in the box, but don’t forget the charger or power bank when you’re heading off for a long one.
The START is supplied with the fish finder, USB cable, barrel swivel and quick-start guide. That keeps the box refreshingly fuss-free. The barrel swivel is useful for connecting it into your setup, but you’ll still want to think about the rod, reel, main line and casting space you’re using. Chucking any sonar unit into snags or tight swims needs a bit of common sense.
For coarse and match fishing, the real win is better decision-making. The Deeper START won’t tell you exactly where the next lump is hiding, and it doesn’t make watercraft redundant. What it can do is help turn a guess into an informed choice. Use it sensibly, read the water as well, and it’s a cracking little extra pair of eyes when a new swim has you scratching your head.

Our take
The bank angler’s extra pair of eyes
The big appeal here is information. Before you clip up, bait a line or commit to a float, you can have a look at what’s going on beneath the surface. That can save a fair bit of blind chucking, especially on unfamiliar lakes, canals and commercial fisheries.
For coarse and match anglers, the value is less about chasing a flashing fish icon and more about understanding the swim. Knowing whether you’re fishing into a shallow shelf, a deeper channel or a sudden drop-off can make your first few casts much more purposeful.
What you’re buying
Small sonar, simple job
The Deeper START is a compact ABS fish finder in black and orange, with a 60 g body that’s easy to carry and cast when the situation allows. Its single-beam 120 kHz sonar scans through a 40° beam, giving you information on depth and underwater changes through a connected phone or tablet.
The Wi-Fi connection reaches up to 50 m, while the battery is rated for up to six hours. In the box you get the START unit, USB cable, barrel swivel and quick-start guide. It’s a tidy package aimed at anglers who want useful swim information without jumping straight into a much more involved setup.
Worth knowing. The START is a single-beam unit. That makes it more straightforward, but the picture won’t be as detailed or wide-ranging as the information from a more advanced multi-beam fish finder.
Best on the bank
A handy tool for finding the better water
It makes most sense for anglers fishing unfamiliar venues or trying to understand a new peg. Use it to compare the near margin with the far side, look for a drop-off, or check whether a promising-looking area has enough depth to be worth a proper go.
For match anglers, it can help with preparation where fish-finding equipment is permitted. For pleasure anglers, it’s useful when you’re moving between swims or trying to work out why one area produces bites while another looks just as good.
Worth knowing. Use it as part of your watercraft, not instead of it. Reed beds, wind, colour, angling pressure and the time of year still matter when you’re choosing a line and deciding where to feed.
Quick answers
The bits you’ll want to know
The minimum scanning depth is 0.5 m and the maximum is 50 m. That covers the shallow margins and deeper areas you’re likely to encounter on most coarse venues, though the useful information for match work will usually be in the shallower end of that range.
A full charge gives up to six hours of battery life, depending on how the unit is used. The Wi-Fi range is stated as up to 50 m, giving you flexibility to stand back while the START is scanning the swim.
Worth knowing. Keep the USB cable and a suitable charging option in your tackle plans for longer sessions. Six hours is respectable for mapping and spot-checking, but continuous scanning can use that allowance quicker than you’d expect.

Your questions answered
What anglers want to know
The stuff you’d ask your mate on the next peg. Straight answers, no waffle.
01How do you use the Deeper START from the bank?
How do you use the Deeper START from the bank?
Attach it to your line using suitable tackle, cast it out, and use the Wi-Fi connection with your compatible phone or tablet. Retrieve it steadily to scan different parts of the swim, rather than launching it once and expecting a full picture straight away.
02What depth can the Deeper START scan?
What depth can the Deeper START scan?
Its stated minimum scanning depth is 0.5 m, while the maximum scanning depth is 50 m. That gives it plenty of range for typical coarse and match venues, where finding changes in depth is often more useful than chasing extreme numbers.
03Is the Deeper START useful for match fishing?
Is the Deeper START useful for match fishing?
Yes, particularly when you’re allowed to use it and have time to map a peg before fishing. It can help identify depth changes and features, but remember that a single-beam unit gives you a focused view rather than a complete underwater map.
What anglers say
