In 1979 we introduced the worlds first electronic propeller inspection system for measuring the pitch of a propeller called Prop Scan. The Prop Scan COMBI measured propellers up to 20-inch diameter and displayed the pitch of a propeller on a digital display. The introduction of the Prop Scan Combi to the market was applauded by those with propeller problems.

With the introduction of personal computers, we combined our propeller measuring system with a computer to do all heavy calculations and produce graphical reports.

In 1985 our computerized Prop Scan was on the market. It measured, processed and displayed propeller information on printed reports. This quantity of information and accuracy of the reports were never before available to the propeller technician. '79 started the electronic revolution in propellers, '85 took the propeller revolution to new heights.

The US, Australian and Canadian Navy got involved with Prop Scan which lead to the development of an under water measuring assembly the was designed to measeure Navy destoryer and frigate propellers.

The Navy interest caused an intense research & development phase that produced more powerful software and many different size measuring assemblies to measure large and sophisticated types of propellers.

In 1995 the first Prop Scan shop opened in Maryland USA. Larry and Allison Carlson started Black Dog Propellers. Larry said, “Prop Scan looks good but I don't know anything about propellers. Can you teach me?” From this grew the world renowned Prop Scan Business Opportunity Program that enabled non-propeller people to start up a professional propeller repair business. We supplied the Prop Scan equipment, the knowledge and training that is needed to operate a successful propeller repair business. Today Larry has a propeller shop called WildCat Propellers in Chesapeake Virginia. WildCat Propellers repairs and reworks pleasure, commercial and Navy propellers.

We have supplied equipment, trained and supported people who were interested in propellers and wanted to establish successful propeller repair businesses worldwide with the primary focus aimed at medium to large inboard propeller repairs.

Many times we have been asked for a less expensive portable unit that included the ‘specialist technology'.

We are happy to announce our design team has achieved this with the launch of the new Prop Tracker Measuring Assembly that has been combined with the new Prop Scan Evolution 4 Reporting System.
