Installing a sonar on a PVC boat is not a luxury, it's a necessity for modern fishing. sonar It's useless if its screen is shaking and its buttons are splashing. sounder-board It's an accessory that transforms the comfort and functionality of your boat, but choosing the right model among dozens of market offers is not an easy task.

In this article, we will discuss selection criteria: from materials and sizes to compatibility with specific models of PVC boats and sonars, you'll learn how to properly mount a table so that the cylinders don't damage, what errors lead to corrosion of mounts, and why cheap "universal" solutions often cost more. Exclusive review of the 5 best tables of 2026 with real feedback from anglersThey tested them in extreme conditions.

Why do you need a sonar table on a PVC boat?

Many newcomers mistakenly believe that the sonar can be simply put on the seat or fastened to the knee with a belt.

  • 🌊 Data loss: on the wave the screen trembles, and the cursor "jumps", making it impossible to accurately analyze the bottom relief.
  • 💧 Moisture intrusion: spray and condensate disable buttons and connectors even in "waterproof" models.
  • ⚡ Battery discharge: unstable position leads to a break in the supply contacts.
  • 🔧 Loss of guarantee: most manufacturers (e.g., Garmin or Lowrance) refuse warranty repairs for mechanical damage from improper installation.

The table solves these problems, but its role goes beyond fixing the device.

  • 📏 Save space: compact tables with folding mechanisms do not interfere with transportation.
  • 🔋 Extends battery life: rigid attachment eliminates vibrations that increase energy consumption.
  • 🎯 Increases accuracy: stable position of the sensor GPS/GLONASS Improves the link to coordinates.
⚠️ Attention.: Cheap plastic tables from Chinese marketplaces often break down when the wave hits the first big one. anodized or stainless steel with a metal thickness of at least 2 mm.

Key criteria for choosing a table for sonar

When buying a table, pay attention to 5 main parameters:

  1. Materials:
    • 🛠️ aluminum (Light, but requires anodizing against corrosion)
    • 🔩 Stainless steel (more solid, but heavier by 30–40%)
    • 🧴 Reinforced plastic (Only for calm water bodies).
  • Type of attachment:
    • 🔗 On the transom. (Similar for boats with a hard transom, for example) Bark 320 or Flagship 360).
    • 🔄 On the balloon. (Universally, but requires PVC protection from rubbing).
    • 🪑 In the seat. (Capacity, but limited access to the battery)
    • Platform size:

      Minimum width is 20 cm (for Garmin Striker 4), optimal - 25-30 cm (for Lowrance HOOK Reveal 7Please note that there should be room for battery-staff or powerbank.

      • Parameter Budgetary models Mid-segment Premium
      Materials Plastic, thin aluminum Anodized aluminum 2-3 mm Stainless steel 3-4 mm
      Max, load. 3kg 5-8 kg 10+kg

      TOP-5 tables for sonar on a PVC boat in 2026

      We have analyzed the reviews in the forums (FishHunting, Fisherman) and YouTube tests to rank reliable models, and the selection criteria are price/quality, corrosion resistance and ease of installation.

      1. RaidPro Alu-Tilt (🇷🇺 Russia)

        A legendary model among fishermen in Siberia and the Far East, a 3mm aluminum platform with a powder coating, angle adjustment in 5 positions. transaxet and rubber-stick Price: 4,200 RUB.

        ⚠️ Attention.: When installed on boats Finger or Aqua You need to buy extended bolts (in the set short).
      2. FishMaster Premium (🇨🇳 China, a brand for Russia

        A universal table with a balloon or a seat attached. built-in powerbank 20,000 mAh Suitable for sonars up to 10 inches (e.g., Humminbird HELIX 7Price: 5,500 RUB.

      3. Tubus Marine (🇵🇱 Poland)

        Premium segment: AISI 316 stainless steel, weighing 1.8 kg, can withstand loads of up to 15 kg. quick-removal It's 10 seconds for dismantling. It's 8,900 RUB.

    How to check the quality of the table?

    Press the paint or anodized layer with your nail. If you have a scratch, after 1-2 seasons, corrosion will appear. The coating should be smooth and not wash off when pressed.

    When choosing, focus on sonar + battery. Lowrance Elite FS 9 It weighs 1.2 kg, and a 12B/9Ah lead battery pack is another 2.5 kg, which is a total load of ~4 kg, which is even possible for budget tables. lithium battery 12V/20Ah (weight ~ 5 kg), you need a table with a margin of safety.

    Step-by-step instructions for installing a table

    Incorrect installation is the main cause of table failures.

    1. Check the complete set of the table (bolts, gaskets, instructions)

    2. Clean the attachment site of dirt and salt (use isopropyl)

    3. Mark the holes with a pencil, considering boat-balancing

    4. Check battery access after installation-->

    Step 1: Selecting a seat:

    • 📍 For transom fasteningStep 10-15 cm away from the edge of the transom so as not to interfere with the motor.
    • 🛟️ For mounting on the cylinderChoose the middle of the boat (more reliable) or closer to the nose (more convenient for driving).

    Step 2: Drilling holes:

    Use it. metal-drill 1 mm less than the diameter of the bolts. PVC boats must:

    • 🛡️ Lock the drilling site down. painterSo as not to scratch the material.
    • 🔧 Put it under the cylinder. board for a flat hole.
    • 🧴 Treat the edges of the holes silicone sealant (for example, Loctite 595).

    Step 3: Table mounting:

    Twisting the bolts cross-overTo avoid skewing.

    • 🔩 For aluminum tables: 4-5 Nm (use a dynamometer key!).
    • 🔧 For steel: 6-8 Nm.
      • 💡

      If the table is attached to the balloon, use rubber-washer They will prevent PVC from being rubbed with friction.

      Common Mistakes and How to Avoid Them

      Even experienced anglers make mistakes when setting tables.

      1. Ignoring Boat Balancing

        A table with a sonar and a battery can shift the center of gravity, like a boat. Dive 330 installation of the table on the stern without a counterweight leads to the "striking" of the nose on the wave.

        ⚠️ Attention.: If after installation the boat becomes worse to obey the steering wheel, move the table closer to the center or add a load (for example, anchor 3-5 kg) in the bow.
      2. Savings on fasteners

        The bolts from the kit often rust through the season. stainless A2-70 or titanium (e.g. from BoltDepotThe cost of the set is from 300 RUB, but they will last 5+ years.

      3. Lack of protection against vibrations

        At speeds above 25 km/h, vibrations from the motor are transmitted to the table, distorting the sounder readings. silicone (for example, VibraTiteor rubber-damper.

      Another common problem is that plug-inEven if the sonar has a protection class. IPX7, constant moisture corrodes the contacts.

      • 🔌 Wet-protective covers for connectors (e.g., Aquapac).
      • 💧 Dielectric lubrication (for example, CRC 2-26) for contact processing.
      💡

      Before each step, check the reliability of the table mounting! Even a slight weakening of the bolts on the wave can cause the sonar to fall overboard.

      Do it yourself: how to make a table for sonar yourself

      If the factory models don't fit in size or budget, you can make the table yourself.

      • 📏 Aluminum leaf 3-4 mm (size 30×20 cm).
      • 🔧 Stainless corners 25×25 mm (4 units).
      • 🔩 M6 bolts with the sleeves and the sleeves (8).
      • 🛠️ Epoxy resin for waterproofing joints.

      Step-by-step instruction:

      1. Cut the platform of aluminum by the size of the sonar + 5 cm around the perimeter.
      2. Weld or fasten corners to the platform (they will be attached to the boat).
      3. Drill holes in the corners under the bolts.
      4. Handle all metal parts corrosion-proof (for example, Zinc Rich Primer).
      5. Cover the platform. rubber-mat (e.g. from 3M) to prevent sounder slip.

      The cost of materials is 1,500 RUB. "" The main advantage of a homemade table is that it's a homemade table. customization for your boat and sonar, for example, Garmin EchoMAP UHD 93sv can be cut under feed-station side of the platform.

      ⚠️ Attention.: When welding aluminum, use it argono-arc welding (TIG)A regular arc will corrosion the seam in 1-2 seasons.

      Table maintenance and care

      To make the table last longer, follow simple rules:

      • 🧼 After every fishing trip flush the table freshwater And you wipe it dry, and you'll pay special attention to the bolt attachment.
      • 🛢️ Once a season metal-work corrosion inhibitor (for example, WD-40 Specialist).
      • 🔧 Six months Check the bolt tightening. The vibrations from the motor weaken the mounts.
      • ☀️ In storage Avoid direct sunlight – UV rays destroy rubber pads.

      If there are signs of corrosion on the table:

      1. Clean the rust metalbrush or sandpaper P120.
      2. Work the place out. rust converter (for example, zincary).
      3. Apply 2 layers primer and 1 layer powder-paint (in canisters).

      For stainless steel tables, it is enough to polish the surface once a year. GOI paste - it'll restore the protective layer of chromium.

      FAQ: Frequent questions about echoer tables

      Can I install a table on an inflatable transom?

      Yes, but with reservations. Inflatable trans-shipments (e.g., boats) Northerner or frigate) cannot withstand heavy loads. Use:

      • 🔧 Table weighing up to 1.5 kg (for example, RaidPro Lite).
      • 🧲 Velcro fastening (for example, 3M Dual Lock) instead of bolts.
      • 📏 Spread the weightPlace the battery separately (for example, under the seat).
      How to secure the table if there is no transom on the boat?

      Options for tranceless boats (e.g. Corvette 310 or Aqua 330):

      • 🛟️ Fixing to the cylinder with rubberized clamps (e.g., FishMaster Clamp).
      • 🪑 Tablet-box The seat is fixed with the screeds.
      • 🧲 Magnetic anchorage (Suitable for aluminum tables and metal parts of boats).

      Avoid drilling cylinders - this violates the tightness and cancels the warranty!

      What height of table should I choose?

      The optimal height depends on the growth of the fisherman and the type of sonar:

      • 📱 For portable sonar (for example, Deeper Pro+) 15-20 cm (belt level).
      • 🖥️ For stationary with a large screen (e.g., Lowrance HDS Live 12) 25-30 cm (chest level).

      Check the convenience can be as follows: sit in the boat, stretch your hand forward - the screen should be at palm level.

      How to protect a table from theft?

      A sonar table is a good prey for thieves.

      • 🔐 The cable-lock (for example, Kryptonite) - tie the table to the seat.
      • 📱 GPS tag (for example, Tile Pro) in the battery compartment.
      • 🖌️ Engraving. with a phone number for metal parts.

      On the nights on the shore, remove the sonar and take with you - even a reliable lock will not stop the intruder with a Bulgarian.

      Can I use the echoer table for other devices?

      Yes, many tables are universal. You can attach them to:

      • 📻 Radio. (for example, Baofeng UV-5R).
      • 📱 Tablet navigational charts (e.g., Navionics).
      • 🔦 Spotlight night fishing.

      The main thing is to check. maximum load table (indicated in the instructions). RaidPro Alu-Tilt It can withstand up to 8 kg, which is enough for sonar + radio + powerbank.
