    Hello,
    I have a Deeper Pro wireless fishfinder + a fishing rod that communicates with a smartphone via Wifi -




    The range of this gem is 80-100 m. For fishing, it is enough, but with a remotely controlled groundbait I go further and Deeper loses range, especially when I "cover" it with a boat. I want to buy a router with a repeater function (I anticipate the questions - there must be a repeater, it is impossible to communicate with the deeper by any other means like the radio).
    In the boat I have one battery 12V10Ah and I do not want to use step-down modules for conversion to 9V, so it is best if the router will work in rated 12V.

    I want to hide the router under the fuselage and drill only the repeater's antennas. My question is which router should I choose - I mean a good price / signal strength and power consumption ratio - 12V10Ah is not too much. I understand that power does not come from nowhere but I do not want to have a power eater :)

    I wonder what effective range I can achieve between such a router and a mobile phone on the water, because it can positively affect the propagation of radio waves. Anyone dare to bet? :)

    I haven't tested yet, for now I will take a regular TP-LINK and test the signal strength in the field, but for now I have no motivation and adequate terrain ;)

    The usual cheap TP link router with a standard antenna located on the roof of the car gave me yesterday a range of 320m. At this distance, it was still possible to ping it and transfer files.

    Located on the ground, so simulating the boat and 200m was not a problem - I didn't want to go any further. I tested the Huawei P10 phone which does not have the best wifi antenna.

    Let us be of good cheer.

    It would be good if such a router had a detachable antenna. In such a case, a good omnidirectional antenna could give a noticeable difference. Open area, no obstacles.

    Only that a good antenna, not sticks for the auction site on which the Chinese wrote what saliva on the language it brought, can be more expensive than a simple router.

    Try to turn off the data transmission on your phone, leave only WiFi. Reset WiFi on your phone, turn off (Kill process) the "Deeper" application and restart. Deeper is so able to "resist" when connected. I have to reset WiFi and the app after each taking mine out of the water for more than 2 minutes. I had it on 2 phones. Colleagues do the same with their Deepers.

    I changed the router to airlive and it started but the range in my eye is not more than 150m. I am thinking about another antenna or wifi amplifier from alliexpres. And you tested deeper with a router?

    I answer after a very long time and you've probably solved the problem ... but if not ... :)

    I also use AirLive (wl-5460ap) with the last available soft. I have not tested the range but it is definitely bigger than in the original Deepera antenna. Soon I will return to the project and carry out some "measurements".
    You write that "by eye" range of 150m. Have you measured? Because more than once when exporting sets with the model, I was very surprised if the eye could be mistaken. Still, 150 is a good result. What exactly AirLive do you use and what antenna?

    With coverage there is such a myk that you will not reach a larger one even by changing the antenna in the router - so the antenna parameters have better if the router was not designed under it and there is not so much power, etc. ... There is a certain output, namely a signal amplifier with its own power supply e.g. SUNHANS:

    Soon I will buy this miracle and check if it works, so if it is a lime, I will let you know if it is worth spending PLN 250

    You thought that by changing the antenna increase the power of the radio, since the power of the radio is always the same and is a maximum of 100mW for 2.4 GHz and 200 mW for 5 GHz according to regulations.

    You can do such games with the Mikrotik RB951G-2HnD - the power of its radio is 1W!

    A friend changed the router because on the tp-link Deeper did not want him to communicate with the app at all. I do not know how he does, but my Apka also did not treat the SSID from the repeater as a Deeper knock I did not give it a name according to the formula "Deeper PRO + IIII" where IIII are any numbers and capital letters - MAC address of Deeper's address. It can be any incompatible with the original mac but the first part had to be preserved.

    In fact, TX in RB951G-2HnD can be set to 30 dBm. Only it has integrated antennas and we want to hide the router in the hull of the boats and put the antenna over its outline isolating so that the water does not get and the hull and electronics do not suppress the signal. Although a 2-3mm resin layer should not damp significantly. I have this model on hand - it's worth testing. Thanks for the hint :)

    But they are also probably attached pigtails, so pigtals can be extended and the antenna itself does not even need to be mounted to the MK housing (and it has a ribbing on the housing) only where it suits you.

    Just remember, 1W power if you have some battery power there and connect the MK, you will have a little battery or battery "current".

    The router looks the same as you, I don't remember the model and now I don't have it with me to check. Antenna no name about 30 cm. I have also tested a router with a directional antenna on the edge but the range is the same. As for the distance, in good weather conditions 150m will do the trick (measured on a fishing line), but a gentle wave is enough and it can lose its range. I was also thinking about this amplifier that you gave, just wondering if it will actually increase the range much. I'm not worried about electricity because the router and amplifier will be switched on from the app and I still don't fly when probing. Have you ever thought about amplifiers and ali? They are much cheaper

FAQ

TL;DR: For Deeper Pro+ over 2.4 GHz, field tests hit 320 m; “ping it and transfer files” still worked. A budget TP‑Link achieved this when mounted high; boat‑level gave ~200 m. Router choice, antenna placement, and app settings matter. [Elektroda, Tomek Sunshine, post #17259099]

Why it matters: This FAQ helps bait‑boat anglers extend Deeper Pro+ Wi‑Fi range on 12 V setups and fix app connection issues.

Quick Facts

How far can a TP‑Link repeater push Deeper Pro+ on water?

Line‑of‑sight testing with a cheap TP‑Link reached 320 m from a car roof. At ground height, about 200 m remained usable. The test phone was a Huawei P10. Mounting higher improved the link significantly. Expect less if the antenna sits low on the hull. [Elektroda, Tomek Sunshine, post #17259099]

Deeper won’t connect through my router—what quick fixes work?

Yes. Disable mobile data, then reset Wi‑Fi and the Deeper app. The app can resist reconnecting after the float leaves water. Use this quick How‑To: 1. Turn off mobile data. 2. Toggle phone Wi‑Fi off/on. 3. Force‑close and relaunch the Deeper app. Users repeated this after 2+ minutes out of water. [Elektroda, Tomek Sunshine, post #17289379]

Does the TP‑Link WA901ND work as a bridge for Deeper?

One user’s TP‑Link WA901ND could not bridge Deeper to the app. They tried AP, bridge, and repeater modes. None worked. Consider alternative hardware if this happens, as protocol quirks can block association. [Elektroda, pitexx1667, post #17263688]

Is AirLive a better choice for repeating Deeper’s Wi‑Fi?

Yes. Switching to an AirLive router restored the link. In that setup, the practical range looked under 150 m. It worked, but coverage was limited. You can later add a better antenna or amplifier if needed. [Elektroda, pitexx1667, post #17293004]

Will a better antenna actually help on open water?

Choose a router with detachable antennas and use a quality omnidirectional. A better antenna can help in open water. Avoid dubious “high‑gain” sticks that underperform. As one expert said, “a good omnidirectional antenna could give a noticeable difference.” Place it high and clear of obstructions. [Elektroda, m.jastrzebski, post #17259651]

I tried a directional antenna but range stayed the same—what gives?

A directional antenna alone may not fix it. One user saw similar range with a directional unit. They also noted, “a gentle wave is enough and it can lose its range.” The weaker device or fading can still limit the link. Keep both ends high and clear. [Elektroda, pitexx1667, post #17404835]

Can a Wi‑Fi booster like Sunhans extend the link?

Consider a powered 2.4 GHz booster. A user planned to test a Sunhans unit with its own power supply. The referenced model cost about PLN 250 at the time. External amplifiers can extend coverage when router antenna swaps fall short. [Elektroda, Tomek Sunshine, post #17400906]

Do antenna swaps increase transmit power, or are we EIRP‑limited?

Swapping antennas does not raise transmit power. “The power of the radio is always the same.” Typical regulatory caps are about 100 mW at 2.4 GHz and 200 mW at 5 GHz. Better antennas change pattern and gain, not the radio’s wattage. Optimize placement and link budgets. [Elektroda, KOCUREK1970, post #17402888]

Is MikroTik RB951G‑2HnD a good high‑power option?

MikroTik RB951G‑2HnD is a viable high‑power option. The TX level can be set to 30 dBm. It uses integrated antennas, so plan pigtails if you must mount the antenna higher. As the expert noted, “TX in RB951G‑2HnD can be set to 30 dBm.” Test before sealing the hull. [Elektroda, Tomek Sunshine, post #17402918]

Can I hide the router inside the hull and keep the antenna outside?

Yes, you can hide the router under the hull and bring antennas out. A thin resin layer around 2–3 mm should not attenuate much. Extend integrated antenna leads with pigtails if needed. Seal penetrations to prevent leaks and corrosion. [Elektroda, Tomek Sunshine, post #17402918]

Do I need to mimic Deeper’s SSID to make the app connect?

Mirror Deeper’s SSID pattern when repeating. Use the format “Deeper PRO + IIII,” with four alphanumeric characters. Preserve the first part of the name. One user reported the app ignored other SSIDs. “The first part had to be preserved.” This trick improved association. [Elektroda, Tomek Sunshine, post #17402918]

Can I extend Deeper’s link any way other than Wi‑Fi repeating?

No. Deeper communicates over Wi‑Fi, so you need a Wi‑Fi repeater to extend range. As the user put it, “it is impossible to communicate with the deeper by any other means like the radio.” Plan for a 12 V router so you avoid extra converters. [Elektroda, Tomek Sunshine, post #17217845]

Will a 1 W router drain my 12 V 10 Ah battery fast?

A 1 W radio increases current draw from a 12 V 10 Ah battery. Plan your energy budget and duty cycle. A contributor warned that with 1 W, “you will have a little battery ‘current’.” Switch the router and any amplifier on only when scanning. [Elektroda, KOCUREK1970, post #17402932]

Where should I place the router’s antenna on a bait boat?

Place the antenna as high as practical. A roof‑level mount gave 320 m in testing. Ground‑level placement held about 200 m. Height and clear line‑of‑sight matter more than raw router specs in this scenario. [Elektroda, Tomek Sunshine, post #17259099]
