Subnado Mounting Guide: Handheld vs Arm, Leg, Kayak, and Paddleboard Attachments

The Subnado ships ready to use in handheld mode. Everything else — arm mounting, leg mounting, paddleboard assist, kayak attach, scuba cylinder — requires knowing which bracket to use and which controller pairs with it. That combination is the part most owners figure out by trial and error.

This guide covers every configuration the Subnado supports, what accessories each one needs, and which Tampa Bay activities each setup is built for. If you have already bought a Subnado and are wondering what else the mounting system can do, start here. If you are still deciding which package to buy, the full Subnado lineup at Elite Watersports shows what is stocked and available.

How the Subnado mounting system works — one quick-release, six configurations

Every Subnado mount uses the same quick-release connection. The scooter unit has a single mounting point that accepts all brackets with one click to lock and one click to release. No tools needed — swap the bracket, swap the controller, and you have a completely different setup.

The main difference between each Subnado setup comes down to which bracket you use, which controller you need, and what activity you are setting it up for.

The critical piece most new owners miss: the controller changes with the mount. The standard thumb controller that ships in the box works for handheld use. Arm and leg mounts need the finger ring controller. Board and kayak mounts need the extended thumb controller. Getting the wrong controller for your mount is the most common Subnado setup frustration.

Handheld with the handle grip — the default starting position

The Subnado Standard ships with a handle grip already included. Clip the scooter into the grip, hold it out in front of you, squeeze the thumb controller, and it pulls you through the water. That is the complete setup.

Handheld is right for:

• Snorkeling trips where you want propulsion without strapping anything to your body

• Pool sessions and recreational swimming

• First-time users learning the scooter's behaviour before trying a body mount

• Children using the Subnado under adult supervision

When handheld is the right choice

Handheld keeps the scooter in your hands, which means you can point it in any direction immediately. For snorkeling in shallow water — Egmont Key, Fort De Soto, the grass flats around St. Pete — handheld gives you the most control over where the scooter pulls you relative to what you are looking at.

The trade-off: both hands are occupied. For underwater photographers or people who want to interact with the reef, the arm mount solves this.

Handheld setup in under a minute

1. Ensure the Subnado is charged and the propeller guard is secured.

2. Clip the handle grip bracket onto the Subnado's quick-release mount (one click).

3. Attach the wrist strap to your wrist — the Subnado sinks when released.

4. Connect the standard thumb controller cable to the Subnado.

5. Double-click the power button to activate.

6. Start in Low gear and confirm the scooter is pulling correctly before increasing speed.

The Subnado Standard ships with the handle grip and standard thumb controller already in the box.

Arm mount — hands-free for divers and underwater photographers

The arm mount bracket is included with the Subnado Standard package. Strap it to your forearm, the scooter clips in via the quick-release, and you control thrust with a single finger on the ring controller rather than gripping a handle.

Arm mount is right for:

• Underwater photographers who need both hands for their camera housing

• Snorkelers who want to interact with marine life without a scooter in their hands

• Divers covering distance along a reef who want arms free for navigation or equipment checks

How to strap on the arm mount correctly

1. Loosen the Velcro straps on the arm bracket fully before putting it on.

2. Position the bracket on your forearm — typically just above the wrist — with the scooter mount facing forward in your swimming position.

3. Tighten the Velcro straps snug but not cutting circulation.

4. Clip the Subnado into the bracket quick-release (one click).

5. Attach the wrist strap from the Subnado to your wrist or the arm bracket.

6. Connect the finger ring controller cable; slide the ring onto your index finger or thumb depending on comfort.

In normal face-down swimming position, the scooter should angle to pull you forward rather than downward. Check direction in shallow water before heading to depth.

Which finger ring controller works with the arm mount

The finger ring controller ships in three types (straight, angled, extended) to accommodate different hand positions. All three control the Subnado the same way — pull the ring to increase thrust, release to stop. Most arm mount users prefer the angled ring, which keeps the cable from crossing the back of the hand in a standard swimming position.

Leg mount — the hands-free "Ironman" setup

The leg mount requires a separate Leg Mount Kit, which does not come in the standard Subnado package. The kit includes two leg brackets, a waist strap, adjustable straps, sponge back pad, and longer Velcro straps (600mm).

This setup is designed for two Subnado units — one on each leg. A single Subnado on one leg creates lateral pull rather than symmetric forward thrust. Most leg mount users own two Standard Subnadoes.

Leg mount is right for:

• Technical freedivers who want completely hands-free propulsion while descending and ascending

• Spring run exploration (Homosassa, Crystal River — accessible from St. Pete on a day trip)

• Divers whose hands are occupied with equipment or photography

What you need for the leg mount (the full kit)

• Leg Mount Kit (separate purchase)

• Two Subnado Standard or Lite units (one per leg)

• Two finger ring controllers (each unit needs its own)

• Two wrist straps (one per unit)

Step-by-step leg mount setup

1. Put on the waist belt and secure it snugly around your hip bones.

2. Attach the leg bracket straps to the calf area of each leg. Replace the standard arm Velcro straps with the longer 600mm Velcro straps from the leg kit.

3. Pass the straps from both sides of the waist belt through the holes at the top of each leg mount; fix with the nylon straps.

4. Clip one Subnado into each leg bracket quick-release.

5. Attach wrist straps to both wrists or to the leg brackets.

6. Connect a finger ring controller to each Subnado.

7. Test in knee-deep water — activate both units to Low gear and confirm symmetric forward thrust before heading to depth.

Paddleboard (SUP) mount — two ways to attach

Mounting the Subnado to a paddleboard turns it from an underwater propulsion device into a surface assist motor. Before the setup details, one honest statement the manual and most product pages skip:

The Subnado on a SUP is propulsion assistance — not a full propulsion replacement. At approximately 3.1 mph (Standard, Low gear), it provides useful push that helps you cover more distance, return against a headwind, and reduce arm fatigue on long tours. It does not convert your board into a high-speed electric watercraft. Set that expectation before you set up.

For Tampa Bay paddlers dealing with the afternoon seabreeze pushing back against them, the assist is genuinely useful.

The nano-sticky SUP bracket — what it is and how it holds

The nano-sticky board bracket attaches to the underside of your board using high-strength adhesive mounting pads (nano stickers), rated to hold against 50 kg of force. The Accessory Box includes six nano stickers — enough to fit one sticker per board you own.

Setup:

1. Clean the attachment point on the underside of your board with isopropyl alcohol — no wax, no debris.

2. Peel the nano sticker backing and press the bracket adhesive firmly to the board for 30–60 seconds.

3. Let the adhesive bond for at least 20 minutes before loading.

4. Clip the Subnado into the bracket quick-release.

5. Route the extended thumb controller cable up to the deck where you can reach it while standing.

Important: The nano sticker bond is strong enough that removing and reapplying is not a quick process. Fit one sticker per board rather than moving the same sticker each session.

Works with: Any board surface — inflatable SUPs, hard boards, bodyboards, surfboards without fin boxes.

The US Fin Box Mount — when to use it instead

The US Fin Box Mount slots into your board's existing US fin box — the same slot that holds your center fin. No adhesive required; removes and re-installs cleanly each session.

Setup:

1. Remove the existing center fin from the fin box.

2. Slide the US Fin Box Mount into the slot and secure per bracket instructions.

3. Clip the Subnado into the bracket quick-release.

4. Route the extended controller cable to the deck.

Works with: Hard boards with a US fin box. Not compatible with inflatables or boards using Future fin box or other standards.

The fin box mount is the cleaner option when your board supports it. For inflatable SUPs or boards without a US fin box, the nano-sticky bracket is the right choice.

Honest expectations — what does the Subnado actually do on a SUP?

On flat water with no wind, the Standard Subnado bracket gives you a consistent push at approximately 3.1 mph. In High gear, it adds meaningfully to your forward speed and allows you to rest your arms while still moving.

Where the setup earns its keep in Tampa Bay: paddling back against the afternoon seabreeze. Tampa Bay's southwesterly seabreeze fills in reliably from midday through late afternoon, and paddlers who go downwind in the morning find the return into 10–15 knots of headwind exhausting. The Subnado's continuous Low or High gear assist reduces that load substantially.

For a second Subnado on your SUP — which increases speed to approximately 4.5 mph — the One vs Two Subnado guide covers the twin-engine board setup in detail.

Kayak mount — same bracket, different application

The kayak attachment uses the same board bracket (nano-sticky or fin box, depending on your kayak hull) as the SUP setup. The extended thumb controller routes to the kayak cockpit rim where your thumb can reach it naturally.

Key positioning check before committing: With you seated in the kayak at normal waterline depth, the Subnado needs to be fully submerged. A bracket too far forward on a short kayak may angle the scooter upward rather than aft, reducing thrust. Test in place in knee-deep water before heading out.

Works best on: Sit-on-top kayaks with relatively flat hull sections at the attachment point. The bracket adhesive needs flat or only slightly curved surface to bond effectively.

Tampa Bay kayak application — where the kayak assist earns its keep

Weedon Island Preserve (northeast St. Pete): The mangrove kayak trails here wind through protected channels — mostly flat and current-free. Low gear provides consistent forward progress without burning your arms for the return paddle.

Skyway Bridge approach areas: Some kayakers access the fishing pier from local boat ramps, which involves open bay paddling. On calm days, the Subnado provides useful assist on the return against wind that has built through the day.

Scuba cylinder mount — for diving with hands free

The cylinder bracket is included in the Subnado Accessory Box or available separately. It clamps to the body of your scuba tank, the Subnado clips in via the standard quick-release.

Setup:

1. Attach the cylinder bracket to the gas cylinder — typically around the lower portion of the cylinder body. Confirm it is secure before entering the water.

2. Clip the Subnado into the bracket quick-release.

3. Attach the wrist strap.

4. Connect the finger ring controller.

On a reef dive, the tank-mounted scooter lets you cover horizontal distance without finning as hard — useful for photographers tracking subjects or divers covering long reef sections.

Depth ratings and what your certification covers

The Subnado is rated to 60m depth. For divers, what matters is your certification limit:

• Open Water Diver: to 18m

• Advanced Open Water Diver: to 30m

• Recreational diving limit (general): 40m

• Technical diving only: beyond 40m

Do not dive deeper than your certification allows because the scooter supports it.

Which controller goes with which mount — the full pairing guide

The controller you need depends on where the Subnado is mounted. Handheld and body mounts use short controllers, while SUP, kayak, and twin-engine setups need longer or dual-control options.

The extended thumb controller is a longer-cable version of the standard controller — the extra length routes from the Subnado mounted under the board up to your hands on deck.

The dual-engine controllers coordinate two Subnado units simultaneously. The dual-engine thumb version is for twin-engine board setups. The dual-engine finger ring version is for two-scooter body setups.

I bought the Subnado Standard and want to use it on my inflatable SUP for Tampa Bay tours — what do I need that is not in the box?

The standard package does not include the SUP mounting hardware. For an inflatable SUP (no fin box), you need:

1. SUP Board Bracket with nano-sticky pads. Available in the Subnado Accessory Box (which also includes the extended controller, cylinder bracket, and spare nano stickers) or separately.

2. Extended Wired Thumb Controller. Also in the Accessory Box. The standard controller cable is too short to route from board bottom to your deck.

Setup order: clean the underside of your inflatable at the attachment point, apply the nano sticker, let it bond for 20 minutes, then clip in the Subnado and route the extended controller to the deck. Stand in knee-deep water first and test thrust direction before heading out onto Tampa Bay.

Session expectation: The Subnado on your inflatable in Low gear provides meaningful assist in flat conditions. Against Tampa Bay's 10–15 knot afternoon seabreeze, it takes the edge off the headwind return without replacing your paddle entirely. In High gear with no headwind, you will cruise at a comfortable speed without paddling.

I snorkel at Egmont Key and want to hold my camera — does the arm mount work in Gulf water?

Yes. The arm mount setup works at Egmont Key, Fort De Soto, and anywhere along the Gulf Coast where you are snorkeling in the surface-to-10-meter range.

At Egmont Key, the current near the channel entrance can be significant on incoming or outgoing tides. The Subnado's 3.1 mph top speed gives comfortable headway in mild current, but is challenging in a strong rip. The arm mount is ideal for the flat-water side of Egmont's beach rather than the channel side where tidal flow can be strong.

Setup for a Gulf snorkel: arm mount on your forearm, Subnado pointing forward, finger ring controller on your dominant hand index finger, camera in the other. Wrist strap on the scooter side. Start in Low gear to approach marine life slowly, switch to High for transit between reef sections.

I have a sit-on-top kayak and paddle the Weedon Island mangroves — will the Subnado work for kayak assist?

Yes, with the nano-sticky board bracket. The flat hull bottom of most sit-on-top kayaks provides a good adhesive surface. Position the bracket in the center of the hull toward the stern half — this keeps the Subnado fully submerged at normal paddling depth and aligns its thrust with the kayak's keel line.

The Weedon Island mangrove trails are calm and current-free — Low gear is sufficient for the whole paddle. The assist there is less about speed and more about reaching further into the preserve without exhausting your arms before the return. The extended controller routes naturally from a stern bracket position to the cockpit rim.
