I am never sure how to rate a product that I haven’t yet used. The unit itself looks really good – solid – well built. The case could be another 1/4″ or so longer because the cords get bent over to – the radius is too tight I think. Sorry I don’t have more info.

Liked easy to learn. Does it’s job. Chased a household circuit by pulling a circuit breaker connecting to it’s outgoing wire with the transmitter then following the circuit through the walls. The house was of 2×4 studs with drywall interior. Thereceiver beeped very well along the path. The tracing was about 40′ from the circuit breaker hookup.

I had high hopes for this device. I run a mechanic shop and it was what i needed to track down some electrical problems with a vehicle. First off as pictured it did not come with Duracell batteries, instead some off brand which i replaced with Energizer as soon as the problems began with using this tool. One of the main reasons i went with this tool was for the cordless circuit tester, but it has not worked like i hoped. I have tried using it in different locations around the vehicle but it only seems to work on the battery terminals to give me an indication of power. It will not indicate ground. I am returning the item due to the fact that i do not trust what it is indicating when running tests and the battery covers should be engineered to be toolless. All battery covers require removing a screw. I realize that is not a big deal but, as many times as i was changing batteries to try to get this to work right, it became a nuisance.

These work well, until they quit working over time. Usually a couple of years in my experience.

If there are wiring problems in your home this machine will track them down. Power OFF. I was under my house for 8 days checking and trying to find out what “they” did. Solved the issue in about 30 minutes. Cut wires, bad connections and crazy person routing can be found out through the walls even from the outside. Worked wonderfully for me and saved me time and money.I also use the same unit to trouble shoot vehicles, 40 footer trailers, and used it to locate shallow underground wiring as well.Mike

I’m russian! And i bought this item for my semy-professional use. I read too many different reviews,watched tons of videos, of this and oter devices… And dicided to buy exactly this one! Fist very big surprise for me was-it’s tottally made in Canada,very pleasant! Fist test was imidiately performed on old type nissan atlas….i checked twice…it works perfectly… power wire with no visible damages at all was broken inside isolation! Next time honda cr-v 99″- check for cont. of injection signal wire from distributor(under hood) to ECU socket, perfect job done les than 5 min. This is very good really,thruly, working device, perfect time saver! Must have! Just only one thig-you need just turn your head on then any missreading goes to 0%at all! Whatever dificult challenge you got, this thig will cut at list time of simple stupid searchings for harness location, cont.y of harness from point “a” to “b”,it’s really matter if you know what i’m talking about.

The FF310 is compact but feels like a quality tool in the hand. Reading the instructions is a must to get a good baseline of the tools functionality. I used it to “test” trace a wire in the interior lighting circuit of a 2005 Jeep Grand Cherokee using the blades in placemnet of the lighting fuse in the main fuse box and I was able to follow the wire without taking anything apart, I did have to use the receiver on its hightest sensitivity setting and it does take a little practice to understand how to maneuver the receivers probe but it worked well none the less. I also used on the same vehicle using the process of disconnecting the RR brake wire at the light and applying 12v to one lead of the transmitter and attaching the other lead of the transmitter to the wire from the brake pedal and it worked just as it did on video. Great tool, I see many uses for it.

I rated it in that manner cause I had to figure it out !but all in all I got it and it took me 2 days but I found the problem it worked well only wish it was louderit did work fine I would not hesitate to use it over n over ,I think I would still be looking for the short still if I did not have it how ever I have a different type I tried using and the results was a waist of time I first received it and in couple days baring the weatherit located it and I was up and running .May I add this was a 92 ranger it stopped cold for no reason known it had fuel and all it did turn over /no start so for those that have same problem this short was down near transmission in wire cluster hope it will help some one ,sorry for the inset but if it helps not to junk it out ,buy a GTC FF310 finder
