A rugged sealed unit that clips to your battery, drops a probe where you want it, and reports home over 4G — no boat WiFi, no hub, no wiring loom. Know your boat is safe from anywhere.
Everything included — no separate SIM, no data charges, no hidden extras. Just clip it on and it reports in.
Every Pulse comes with a 3 m fused battery lead terminated in ring terminals, a waterproof temperature probe, and the SIM already fitted and activated. Nothing to configure and nothing else needed to start monitoring.
Know the moment a cabin, locker or hatch is opened. Wireless, sticks on in two minutes, arrives already paired.
Told within seconds if water reaches the bilge — and told again if the cable itself ever fails.
Built to order · Free UK delivery · 14-day returns
Thanks — you're on the list. We'll be in touch the moment Pulse ships.
Every Pulse is built and tested individually. We don't mass-produce them and we don't drop-ship. When you order, yours is built, bench-tested on a real battery, and posted out.
You'll get an email when yours goes into build, and again when it ships.
The fused lead connects straight to your leisure or engine battery. No tools beyond a spanner.
Run the temperature probe to the engine bay, battery box or cabin — wherever you want eyes.
Open the ElecBot app and scan the code on the unit. It pairs to your boat automatically.
Live readings on your phone, alarms by email and in-app — even mid-mooring, mid-winter.

You don't need an installer or a manual. Ask ElecBot how to set up your Pulse and it walks you through every step — fitting and powering the unit, opening the live monitor, and pairing it by scanning the QR code or entering the device ID.
It already knows your boat, so the answers fit your actual setup. Ask it anything, at any point.
Ask ElecBotThe Pulse is yours to set up and run. Fit it, pair it, and decide exactly what you want to be warned about. No installer visit, no locked-down settings.
You choose the thresholds. Decide the low and high voltage that matters for your battery bank, and the temperatures that should trigger a warning. Change them any time from the app — nothing is fixed at the factory.
Enter your own email address and the alerts come straight to you — wherever you are. The moment a threshold is crossed, your boat moves out of its geofence, or the unit drops offline, you'll know.
One Pulse doesn't mean one pair of eyes. Add family, a co-owner, your skipper or the marina office so more than one app can watch the same boat at once — everyone sees the same live data and gets the alerts.
From fitting it to setting it up, the Pulse is designed to be owner-friendly — you're never waiting on anyone else to change a setting or add a person. It's your boat, and it stays in your hands.
The Pulse reports straight into the ElecBot app — your boat's vitals and your alarm setup, live on your phone.

Battery voltage and state of charge shown inside a boat graphic, a thermometer with your own alarm lines, and position on tap. One glance and you know your boat's fine.

Set your own high and low temperature limits and voltage points, and add whoever should be told. Everyone you add is emailed the moment something crosses the line.
Your Pulse watches the battery on its own. These two let it watch the boat. £49 each, and they can be added when you order or at any point afterwards.
A small wireless sensor on a cabin door, a locker or an engine hatch. Your Pulse listens for it directly — no hub, no WiFi and no second app to set up. The app updates within seconds, and you get an email.
A marine float switch in the bilge, wired back to your Pulse. If water reaches it you're told within seconds — wherever you are. A boat taking on water at its mooring is the most expensive thing that can happen to it, and almost always the most preventable.
The bilge water alarm tells you there's water. It doesn't pump it out, and it isn't a substitute for a working bilge pump. If you want your Pulse to switch the pump on as well, that's a custom build — see custom switching below. Plenty of owners have both.
The headline stuff most owners need — with the full technical spec a click away for the engineers.

Pulse doesn't just watch your boat. It can act. Alongside the standard battery, temperature and GPS monitoring, we can build your Pulse with remote switching tailored to exactly what you need — controlled from anywhere, straight from the app.
Not a call centre, not an off-the-shelf module. Tell us what you want to switch and we'll spec, build and configure a Pulse for your exact setup. If it's not on the list, ask — if it can be switched, Pulse can probably switch it.
Custom Pulse units are built to order and priced individually. Switching functions should be fitted by a competent installer.
