Good gear starts with a clear job.

How we choose what to cover

We begin with a specific problem, such as inspecting a suspected leak or viewing a circuit board while soldering. We identify the criteria that change the buying decision, then compare relevant models using manufacturer documentation and other attributable sources. A product's presence in our research catalog is not an endorsement.

How our comparisons work

1. Define the use case and the buyer's constraints.
2. Check model identity, compatibility, and important specifications against source material.
3. Explain the practical trade-offs and who should choose something else.
4. Check product and affiliate destinations before linking a recommendation.
5. Revisit a guide when specifications, subscriptions, or models materially change.

We do not claim to have purchased, handled, or tested a product unless we can document that work. Source-based analysis is labeled as such. Readers should confirm current details with the manufacturer before buying.

Editorial independence

Affiliate relationships may support the site, but they do not establish a product's suitability. We do not publish paid rankings or invent ratings. Where evidence is insufficient, we withhold the recommendation.
