I purchased this OBD2 scanner mainly for the engine fault finding and it has proved to be a very useful tool for the job. I have had several codes and the scanner has allowed me to rectify them myself. I had one problem that required a Dealer scan and this was provided without charge when I took my car in. 

The software supplied with the scanner is very comprehensive. It is not as easy to use as some of the other scanners on the market. This unit has more features than I expected, including adjustments or re-mapping of various parameters of my vehicle.

I use it for testing the engine, airbag control module, freeze frame data would be handy and the one-touch button start/stop function. It is well-built, has a nice display, a sleek design, and easy controls. Although this unit costs more than a basic scan tool it is worth the extra money in my opinion.


  • Very informative.
  • Easy to use. 
  • Comes with a very good instruction booklet.
  • Lots of extra features.
  • Very fast OBD2 scanner.
  • Has a nice, big screen.
  • The price is reasonable.


  • The scanner may not support all language versions, only English and Spanish are supported.

The system is capable of performing these tests quickly due to the fact that it can be programmed to do large amounts of diagnostics within a short period of time.

The BT705 is also capable of generating freeze frame data for all components in your vehicle’s electrical system that have the ability to produce this type of data.
