A used DEKA ONDA Plus price follows the component list more than the console. The generator alone is one asset, the generator with a defined applicator set is another, and the two can carry very different prices because the applicators do the work the clinic pays for. The buyer should score every offer on a package-completeness ledger: each component the system can carry is listed, each offer is marked included, optional or absent, and every missing component is priced as a buyer-side cost rather than treated as a saving.

This completeness-ledger method is for clinic owners and procurement managers comparing used ONDA Plus offers. Because the system is generator-based with interchangeable applicators, two offers with the same model name are different assets when their component lists differ; the ledger makes that difference visible before any total is discussed.

The ledger is built component by component before the buyer reads a price. An offer that cannot be placed on the ledger is an offer whose completeness is unknown, and the buyer prices that unknown instead of assuming the missing parts can be sourced cheaply later.

On the ONDA Plus, the applicator set is where package value concentrates. The generator establishes the platform, but the applicators define what treatments the clinic can actually run, so an offer that says only “complete system” without naming the applicators leaves the most important part of the price undefined.

Define the generator and applicator package included in the offer

Open the ledger by naming the generator model and configuration, then list every component the offer includes: applicators with serials, cables, accessories, software state and documentation. The definition goes in first, because a price without a defined package cannot be evaluated or compared.

Mark each component as included, optional or absent. The three marks decide the completeness score, and an offer that leaves the marks blank is an incomplete offer regardless of its headline price.

Compare the component list against the configuration sheet the seller attaches to the offer. Where the listing, the configuration sheet and the serial records disagree, the buyer should treat the offer as unverified rather than assume the most favourable version is correct.

Ask the seller to confirm the package in writing and to name which applicators are priced separately. The written confirmation is the delivery baseline; the buyer should treat a verbal package list as an open gap, not an oversight.

Watch for offers that describe the set in general terms such as “with applicators” while the quoted figure covers only part of the set. The buyer should ask the seller to list each applicator serial in the offer and to state which applicators the clinic would have to source separately.

Verify applicator identification and service records

Verify each applicator’s identity: serial, model designation and label state. Applicators are replaceable components with their own history, and their identity defines what the offer actually contains.

Request the service records for the generator and for each applicator: dated maintenance, repair and replaced-part records with attribution. The records establish what was done to the components, and a component without records has an unverified history that the ledger prices accordingly.

Match the serials across the listing, the invoice and the records. A mismatch affects both configuration and price, because the offer may describe a different set than the one delivered; the ledger records the mismatch as a completeness finding.

Check the condition of the applicator connections and cables as part of identity verification. An applicator that carries the right serial but a damaged connector is not the same deliverable as one whose connector is intact, and the ledger should note the physical state beside the serial.

Separate generator condition from applicator-condition claims

Keep generator condition and applicator condition on separate ledger lines. A generator with clean records and applicators without records is a different offer from a complete set, and the two are never priced as one item.

For every component the buyer should collect dated findings: the generator’s exterior and cooling, and each applicator, cable and connector in the set. The ledger treats a finding as the only condition evidence, so a component described without one stays on the ledger as a claim rather than a fact.

Where the seller describes applicators as within usable life, require the usage and service records that support the description. An unsupported claim leaves the applicator-condition line unverified, and the ledger prices that uncertainty instead of accepting the claim.

Watch for records that stop at a sale date. A service history that ends when the unit changed hands tells the buyer nothing about the period since, and the seller should account for what happened between that date and today; if no record exists for the post-sale period, the ledger keeps those components at the partial tier.

Account for software, protocol, installation and delivery costs

Software is part of the asset. Ask which version the unit runs, whether updates or licences are included and what the written terms commit; a price that ignores the software state is incomplete because the applicator behaviour depends on it.

Check whether the official documentation and protocol material are included and current for the configuration. Documentation is a deliverable, and its absence is reflected in the completeness score rather than treated as a minor omission.

Ask which software or protocol version the delivered applicators require and whether the generator in the offer supports it. A generator and applicator set that are not on the same documented version state can carry update costs the buyer would otherwise discover after purchase, and the ledger records the version answer beside the software row.

Add installation, training and delivery as separate cost lines: installation, operator training, shipping, customs and insurance. Each is a cost the buyer will face, and the ledger shows them for every offer so the landed cost is comparable.

Compare warranty, service access and excluded applicator risks

Warranty rows compare the same five elements across offers: the parts covered, when cover starts, how long it lasts, what is excluded and how a claim is filed. For a used ONDA Plus the written terms are the only coverage the ledger counts.

Ask which service providers work on ONDA Plus systems in the buyer’s region, what response they commit and which parts are stocked locally. An offer that cannot show a service path carries a downtime cost, and the ledger records the parts position so the buyer can weigh downtime against price.

Ask which provider would perform the first service after delivery and what that service would cost. A unit that needs generator calibration or applicator verification shortly after arrival carries a near-term cost the buyer should price now, not discover in the first months of ownership.

Check how the offer treats applicator replacement outside coverage. Excluded applicator risks sit beside the warranty line because they change the real cost of ownership more than the headline warranty length.

Complete the ledger for every offer in the same structure and compare only the completed rows. Where an applicator is missing, add the buyer-side sourcing cost for that applicator to the offer total: a missing applicator is not a saving, it is a cost the buyer will pay later, and the ledger shows it as such.

Normalise offers that include different applicator sets before comparing them. If Offer A includes two applicators and Offer B includes one, the comparison should price the missing applicator in Offer B at the buyer-side sourcing cost rather than treating the two totals as directly comparable.

Keep the comparison inside one validity window and one sourcing basis. Applicator pricing and availability move, so the buyer should note the date and the source used for each buyer-side cost; a comparison built on stale sourcing figures will misprice the missing components.

Once every component row is marked and sourced, ask the seller for a current itemised quote for the DEKA ONDA Plus, with configuration, condition, included support, shipping and warranty scope shown separately. The platform context is in the ONDA Plus comparison guide, and the ONDA Pro launch guide covers the sibling platform; DEKA ONDA systems is the product reference.

Frequently Asked Questions

Why is package completeness the spine of the price?

Because the ONDA Plus price follows the component list: a bare generator and a full applicator package are different assets. Scoring completeness first is what stops a headline price from hiding a missing applicator set.

How should the buyer price a missing applicator?

Add the buyer-side sourcing cost for that applicator to the offer total. A missing applicator is not a saving; it is a cost the buyer will pay later, and the ledger shows it as such.
