For the independent outfitter, marine repair counter, and small charter supplier that buys public-surplus gear with a bench, a pallet jack, and a real resale channel. Lothound shows what the lot costs after the auction invoice, freight, and refurb exposure — then tells you whether the margin clears your own floor before you bid.
These are the public-surplus lots a small marine specialist can actually turn: an outboard through the service bay, a tested electronics pallet, or serialized charter gear with the paperwork and recertification accounted for.
Compression check on file, lower-unit oil inspected, cowling scuffs but no impact damage. A small shop can service it, photograph it, and put it back into its own sales channel.
Two TZTL12F units, one TZTL15F, and one RD-30 display head. Burn-in hours are logged; one unit needs a board-level recap before it ships with a bench warranty.
An ACR EPIRB with battery due, a six-person life raft at repack interval, and an ICOM M605 VHF. The chain of custody is clear, but recertification exposure belongs in the bid.
You set the floor for each niche you buy. Lothound applies the matching threshold to the matching landed-cost math; an alert fires only when that niche clears, not when a different kind of marine lot happens to look profitable.
Set the margin floor around horsepower, hours, compression risk, and the labor your bench can absorb. A clean F250 and a tired 9.9 kicker should not share one alert rule.
Use a different floor for MFDs, radar, AIS, and autopilot gear. Board-level repair, missing harnesses, and test-bench time can erase a percentage that looks good at auction.
Set the floor against pallet and unit mix for cleats, floats, shore-power pedestals, piling wraps, and galvanized hardware. Freight and sorting time matter as much as the hammer price.
Keep serialized gear on its own threshold. EPIRB batteries, life-raft repacks, VHF testing, and documentation are not optional costs when the buyer is a working charter fleet.
Historical Comparables give you trailing 60-day matched-sales context for the exact kind of gear in front of you. Before the comparison is useful, Lothound nets out the buyer’s premium, freight, and realistic refurb exposure. That leaves a resale band you can use to set a bid ceiling instead of a retail number that ignores the work.
The result is a quieter feed and better calls at the auction: the alert is tied to the horsepower and hours, model and package, pallet mix, or serialized recertification state that actually changes what the shop can sell.
Start with marine and one adjacent niche on Tracker, or open every vertical with Full buyer. Either way, your marine alerts use the thresholds and landed-margin math you actually buy against.
