    Does anyone have a recomendation on a good frequency sounder for measuring water levels of well with DROP PIPE INSTALLED?
    I am researching an Eno Scientific 2010 Pro and I cannot find a single review of this product.
    Thanks in advance. Jason

    The most accurate way is to use an air line. I use 1/4" poly with a pressure gauge and schrader valve on a tee up top.

    We use one of theses and they work very well. 2 nice features are they see past torque guides and arrestors, and that you can use automatic static water level logging for tests more than a few hours or days.

    If you make a living testing existing wells I think the $1000 would be worth it but you can buy a lot of 1/4" poly for that much. Mind you, taping 1/4" poly to the downpipe is really only practical when setting a pump.

    Thanks for the feedback so far...The fact that it can "see" past torque arrestors is amazing, never thought to even ask that. As for the poly lines, we deal with a lot of residential wells that have existing pumps set and need to know their pumping levels for upgrades, water levels newly drilled wells(deep) and in monitoring wells etc. I'll keep checking here for more user feedback.
    Also is anyone using a different sounder for this application that I can research and compair?
    thanks again

    Well, the owner of my company just bought 2...Ive tried it on our office well and it is simple and accurate. I will keep you all updated as we use them.

    So, we have been using this water level meter for a couple years now and due to the inconsistencies, we have purchased another meter from Ravensgate. The problems we have had with the Eno Scientific model are that you need a sealed well to keep the "puff" of air in the casing. However, even with a well seal we continue to get inaccurate readings with both of the meters we purchased.
    The 'sonar' from Ravensgate has not failed us yet, we have been using it for a year and have gotten very accurate readings every time.

    Thank you for that information. I have wanted to buy one in the past but didn't know if there were any drawbacks.

    I've got 2 Eno Scientifics and 2 Ravensgates, I think they're both good units but can give inconsistent readings at times especially in cable tool wells where there is a lot of borehole size deviation.

    We use a plastic coffee can lid on top of the well with the Eno unit to help give more accurate readings.

    I've also got both the ravensgate and the eno sonic meters. They don't work in all situations. They work in maybe 70% of the wells I check. You have a reading in a matter of seconds. If they work great. If not, it's plan B.

    I can't count how many tips I've pulled off of electrical depth sounders, or got stuck and had to leave behind until the pump was pulled.

    An airline is the best permanent depth sounding method. I use either 1/4" polyethylene tubing at 11 cents per foot or 1/4" air brake tubing at around 40 cents.

    If I install a down hole pressure transducer, it goes inside 1" or 1 1/4" flush thread PVC.

    We only use sonic indicators, they're quick, easy, fairly reliable, no cross contamination, nothing stuck in the hole and cost effective.
