Q: Why am I not getting full range anymore?
A: As with most electronics the stronger your battery life the more performance you will get out of it. So we recommend using fresh batteries for every locate.

Q: I am using a receiver other than Prototek and I am not getting the range that you advertise on your website. What is the deal?
A: Our receivers are very sensitive, they tend to pick up the signals a little better than others. All our ranges posted on our website are determined with our receivers. We can't guarantee what you will get with other brands of receivers.

Q: How would I push this large of a transmitter down the line?
A: We highly recommend use with a tractor camera. This is the easiest and safest way to put this large of a transmitter down the line. Some customers go as far as getting some PVC pipe and two encaps. This would be like a makeshift spring carrier and is a great way to protect your transmitter.

Q: Can I use this transmitter with my jetter?
A: Yes you can. There are a couple things to keep in mind. First, this is a very larger transmitter and we only recommend you use it with a jetter hose 2” and above. Second, make sure you securely tape it at least 4 feet behind the jetter head.

    These Sonde's work great and put up with daily abuse. The good strong signal keeps bringing us back to this Sonde when we just can't pick up other units. Just keep the contacts clean and it will work for a long time.
