Peak or Null

[Goldenboy]

Do you use both peak and null or just one of them?

I only use peak. I've tried using null and I just don't like it. I know for hiking a long stretch you can fly in null but for some reason I just don't like null.

I know alot of people don't like the pinpoint peak on the Rycom but I love it. I will check in the normal peak mode on my walk back but primarily use the pinpoint peak.

I've been doing this for almost nine years and only in the last year or so have I really started using the null mode on my RD. More than anything I've just found it's another tool to help identify a line.

I only use Null if I'm unsure of the tone I'm getting in Peak. I was trained that the Peak option uses two (2) antennas , whereas the Null option only uses 1. On the other hand it's kind of neat to get both arrows at the same time in Null

I've only used null on a 'deep' line. Still wasn't sure on the accuacy of it though.

[gypsygirl]

I will use it for help in verifying a line.... but as a general rule I use peak.

It is good practice to check yourself in null every so often and yes, you can fly on long stretches. However, you should remember that null is not very accurate on corners & turns.

Especially with the RD's, you can wonder off your target line & not know it if there are bends in it. Therefore, locate in peak & verify in null is the best way.

It's a good & effective tool when used properly, the problem is lazy locators like to depend on the little arrows & then you get mismarks...

I was taught that peak was more accurate than null so depend on peak but verify with null. On a non-distorted locate (good locate signal), the peak and null should line up, verifying its accuracy. On a distorted locate (bad locate signal), the peak may be slightly off the mark, but the null could be way off the mark. Therefore a good practice would be to walk out your locate in peak and walk back in null. Then you can verify your locate accuracy and also identify any field distortion. If one doesn’t realize that they are locating a distorted signal, they could unknowingly mark inaccurately.

peak for me......never was trained for null......

I like using the RD null when I'm inducing utilities without the coupler.

I agree with frosty on all points. Peak will pinpoint the 90 degree corners for me where null will not.

I will use peak mode to locate and nul mode to verify accuracy.

I was not taught NUL mode in the training class the company offered. It was only when I took a course at Canada's equivalent of the staking university did I learn about NUL mode.

back in the day i used peak and now im hooked on null its i think its better on the locate than peak is,

I love my metrotech. quick and easy.Haven't had a corner problem yet.

I don't understand the physics of it, but the metrotech 810 seems to be the exception to the rule. I know I love mine. My comments above are mostly towards using RD's & Subsites. Those are the 3 pieces of equipment I know the most of.

[LadyLeatherneck]

I learned on the 810. GREAT PIECE OF EQUIPMENT!

Exactly, use it to verify your locate..... Unless your an old timer, and like the null response......
