Seaward PAC3760 DL Review
The Pros – Battery powered with simple one-button testing. Build-in RCD testing with Isolation Transformer. Entry-level option for data storage and tag printing.
The Cons – Can't customise or edit saved data. Doesn't perform a 250V insulation test (needed for surge boards). Printing is still fairly limited.
The Bottom Line – The PAC3760 DL packs a lot in for the price - battery power, data logging, RCD testing, and tag printing for around $1400 sounds like a solid deal. But in practice, it’s not quite as seamless as it appears on paper. That said, it’s still a clear step up from basic testers and remains a budget-friendly choice for low-volume users.
Key Features of PAC3760 DL
If you’re looking for an entry-level tester in 2025 with a few extra bells and whistles at a cheaper price point, the Seaward PAC3760 DL might catch your eye. It’s one of the only PAT Testers in this price range that also handles RCD testing, basic data logging, and tag printing (with the right add-ons of course). On paper, it looks like a strong all-rounder, and for some users, it is. But as we’ve seen firsthand with our updated breakdown, it isn't all smooth sailing.
Battery Operation
This was once a massive selling point for the PAC3760 DL, although a lot of appliance testers these days are now battery operated. However, this is still a massive plus if you're on the go or working in environments without easy access to power. Ideal for mobile setups and on-site work.
Basic Data Storage & Limited Detail
The PAC3760 DL can store up to 999 test results, which can be downloaded to your computer via USB in a spreadsheet format. Fields include item ID, test type, date, and result, but that’s it. You can’t edit or add extra data fields, which can be frustrating for users managing a large volume of gear.
Basic Tag Printer with Add-On Printer
This comes sold as the PAC3760 DL Print Pack that utilises the PAC-OPT printer, which lets you print tags on the spot. You press PRINT after each test, and a tag is generated. But it’s not seamless of course - you’ll still need to handwrite your name on each tag, and the layout is fairly basic. It’s fine for casual use but not ideal for high-volume workflows.
Easy One-Button Testing
There are 9 dedicated test buttons, so you don’t need to scroll through menus or navigate complex options. Each button corresponds to a specific electrical test. This is great for new users or those who just want to get on with it. Test results are clearly displayed on a bright LCD screen.
RCD Testing Built In
Unlike some portable appliance testers in this price range, the PAC3760 DL includes a built-in isolation transformer, so it can properly test 10mA and 30mA portable RCDs out of the box. No extra gear required, which is handy and keeps your setup simple.

Optional 3-Phase Testing
Supports 3-phase testing via the PAC-TPL adaptor (sold separately). This adds flexibility for users who might work across standard and industrial appliances - but it’s not built in, and won’t be needed for everyone.

How it Performs in the Field
If you're coming from a manual PAT tester or something more basic, the PAC3760 DL will feel like a step up. Battery power is a game changer for portability, although as mentioned previously, the majority of testers in this price range will have battery power these days. The one-button test layout makes it easy for anyone to use without training.
But if you're used to smoother workflows or modern appliance testers with smarter features, this unit can feel a bit outdated. The lack of a 250V insulation test is a pain point for anyone working around surgeboards. And while data logging and printing are technically available, they feel like afterthoughts as they're not fully integrated.
It’s reliable for low to mid-volume use, but as soon as your testing needs grow or you start chasing efficiency, you’ll notice its limits.
Is it Worth the Investment?
If you’re looking for a appliance tester that covers all the bases - RCD testing, data logging, tag printing, and even 3-phase compatibility - the Seaward PAC3760 DL ticks a surprising number of boxes for its price point. It looks like it does it all, and technically, it kind of does. But don’t be fooled by the feature list alone. While it covers most of the functionality found in premium testers, the execution doesn’t quite measure up. It’s a great option for light-duty or low-volume use, but if you’re after speed, depth of reporting, or long-term efficiency, this probably isn’t your forever tester.
