The short answer

A crane crew member needs to stay in reach of the crew while the crane moves, often by headset and sometimes by a visible signal on a phone. OperatorLink shows STOP, HOLD and SLOW to the jobsite crew and passes button presses, chat and voice between phones in a browser ^[3]. Sena Industrial's pages describe lightweight general-use communication headsets for industrial applications ^[1] and headsets with noise reduction and hardhat integrated options ^[1]. The Eartec facts cited on this page describe a commitment to customer support that spans over 60 years ^[2] and a buy-and-return policy ^[2]. Which fits depends on whether the crew wants headsets to talk or wants signal alerts sent to phones.

What Eartec, Sena Industrial is built for

The Sena Industrial facts in this section come from its own pages and describe the product's place on a worksite. Sena offers lightweight general-use communication headsets for industrial applications ^[1]. Its headsets offer noise reduction and hardhat integrated headsets ^[1]. One model, the Sena Expand Mesh, is a compact communication headset built for easy group communication ^[1]. The Eartec facts allowed in this section describe its support and its return promise rather than the headset itself. The company says it has provided customer support for over 60 years ^[2]. Customers can buy a set, try it, and return it for a full refund if they do not like it ^[2]. What Eartec does with signals on a jobsite is not described by the facts allowed in this section, so a crew should check it directly with Eartec.

What OperatorLink is built for

OperatorLink is made by the team that publishes this site. For a crane crew member, it shows STOP, HOLD and SLOW to the jobsite crew, and passes button presses, chat and voice between phones in a browser ^[3]. A STOP releases every held direction on every phone and shows a full-screen alert to everyone else ^[3]. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves ^[3]. Holding a move button keeps sending that move to the other phones, and if the move stops arriving for 2 seconds, the other phones drop it ^[3]. One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages ^[3]. Anyone who joins can take part in a voice call run from the phone browser ^[3].

Pricing and fees

Neither Eartec nor Sena Industrial states a price in the facts gathered for this page, so their prices are not published here. A refund promise is the only money fact given for Eartec: customers can buy a set, try it, and return it for a full refund if they do not like it ^[2]. OperatorLink is currently free to use, and no paid plan is built yet ^[3]. The card fee is not published for any of the three options. A crew that expects to pay a card fee or a set price should ask each provider for it before choosing.

Setting it up on a jobsite

OperatorLink runs in a phone browser with no app install ^[3]. The person who starts a jobsite shares a link or QR code, and the crew joins from it ^[3]. Phones can add the app to their home screen as a standalone app ^[3]. A jobsite link stops working 12 hours after the first person joins ^[3], and a jobsite with nobody in it is wiped after 3 idle hours ^[3]. This page holds one setup fact for Sena: the Expand Mesh is a compact communication headset built for easy group communication ^[1]. The facts gathered here do not describe how Sena pairs headsets or how a Eartec set is set up, so the crew should confirm the rest with each maker before a shift.

Things to check before you choose

Does the crew need headsets to carry a conversation, and does the job site background noise call for noise reduction? ^[1]. Would a hardhat integrated headset suit the crew, and is that fit confirmed for its specific hardhats? ^[1]. Which return terms apply if a set is bought and returned, and are the items undamaged inside the refund window? ^[2]. How long does the crew's shift run, and does a jobsite link that stops working 12 hours after the first person joins suit it? ^[3]. How will the crew test that a chosen tool passes each signal and each voice message before a lift?

How to choose

If the crew needs a headset that filters background noise, Sena's pages describe noise reduction and hardhat integrated headsets ^[1]. If the crew wants lightweight general-use communication headsets for industrial work, Sena Industrial's pages describe that ^[1]. If the crew wants a compact headset for easy group communication, Sena describes the Expand Mesh ^[1]. If the crew wants a free start with no paid plan, OperatorLink is currently free to use ^[3]. If the crew wants signals such as STOP shown on every phone, OperatorLink's sources describe that ^[3]. If the crew wants a buy-and-return promise before committing, Eartec's page describes a full refund if the set is not liked ^[2]. A set price for Eartec or Sena is not published here, so a crew comparing cost should ask each maker directly.

Frequently asked questions

Is OperatorLink free to use?

OperatorLink is currently free to use, and no paid plan is built yet ^[3]. The facts gathered for this page give no price beyond that. The card fee is not published for any of the options on this page. On Android browsers a signal such as STOP makes the phone buzz, while iPhone Safari ignores the buzz, so check whether that matters for the crew ^[3]. Prices can change, so confirm current terms before a shift.

Does Sena Industrial make headsets with noise reduction?

Sena Industrial's page says its headsets offer noise reduction, over-the-head earmuffs, and hardhat integrated headsets ^[1]. It also describes lightweight general-use communication headsets for industrial applications ^[1]. The facts do not give a price for Sena headsets, so that is not published here. A crew working around loud machinery should check which Sena model matches its noise needs.

Can a set bought from Eartec be returned?

Eartec's page says customers can buy a set, try it, and return it for a full refund if they do not like it ^[2]. The facts gathered for this page do not give a price for an Eartec set, so that is not published here. Ask Eartec for the full return terms before choosing, because the facts here do not state a refund window or condition.

Does OperatorLink show STOP, HOLD and SLOW?

OperatorLink shows STOP, HOLD and SLOW to the jobsite crew and passes button presses, chat and voice between phones in a browser ^[3]. A STOP releases every held direction on every phone and shows a full-screen alert to everyone else ^[3]. HOLD and SLOW stay on for everyone in the jobsite until the last person leaves ^[3]. A crew that needs these visible signals should see if the phones it uses can show them clearly.

How does Sena Industrial support group communication?

Sena Industrial's page describes the Sena Expand Mesh as a compact communication headset equipped with Mesh Intercom technology that allows for easy group communication ^[1]. The facts gathered here do not give steps for pairing or pricing for Sena headsets. A crew that wants easy group communication on the job should confirm how the Expand Mesh pairs with its own radios and headsets before relying on it.
