Comments from customers who have retrofit our RV Tank Monitors

  • I purchased the SeeLeveL II, model 709-HP3W, and could not be happier.  This is a well-designed product and the documentation is superb. Thanks for designing a great replacement product for my old-fashioned LED tank monitoring system. (Oct 2019)

  • I recently installed a Model 709 tank monitor system in my Winnebago. As a retired electronics engineer, I can appreciate the quality of this product and the thought that went into its design.  I would like to thank the engineer that designed this fine instrument and point out that the overall cost of the product it’s money well spent and a sign of quality workmanship.  Thank you for the effort!

  • We’ve been RVing for 3 weeks. We couldn’t be more pleased with the SeeLeveL system. The consistency and accuracy have given us great peace of mind.

    We now comfortably go a week between dumping the gray water tanks and we’re approaching 2 weeks on the black water tank. The freedom of not dumping unnecessarily because we can’t trust the sensors is truly fantastic.  (2019)

  • Tom, Received the unit Friday morning and installed it on my 3650 Cruisers on Saturday. Works Perfectly!  Was easy to install and wire. You have a great product, and 4 other boaters in the marina have already looked at my system.  Thank you

  • Our coach came with the standard tank monitoring system that read in thirds (Empty, 33%, 66%, Full) and the associated in-tank sensors that were prone to erroneous readings. I wanted something more accurate with a finer resolution and a sensor system that wasn’t susceptible to bad readings from effluence. Queue the Garnet SeeLeveL monitoring systems. I ended up installing our primary display above the pilot’s seat in place of the old display. I also installed a secondary display in the actual wet bay which I’m sure my kids are happy about; they don’t have to babysit the primary display and call out the readings to me while I’m doing tank maintenance. It took a few hours with some basic tools and it was well worth it! This may be my favorite bang-for-the-buck mod so far. (2019)

  • I have just had installed on my fifth wheel trailer a set of 709-4 tank gauges. This is the second trailer I have had these gauges installed on and they are the absolute best. The set on the first trailer remained accurate for years until I sold that trailer. The gauges they install at the manufacturer in most cases are fairly useless and inaccurate. I would gladly pay extra to have the Garnet gauges installed at the factory. I have had occasion to contact your Customer Service and found them to be helpful and responsive. Thanks for providing a great product! Now my wife won’t run out of fresh water while in the shower. You simply can’t let that happen more than once!

  • Great product – I should have installed one of these about 55,000 miles ago (we have 60,000 miles on our 2005 Itasca Horizon 40AD) and we’re anxious to use it while we’re on the road all summer! Eight-page install article: www.janeandjohn.org

  • I thought I’d send you folks a link to an installation article I posted on an RV forum website I am working on. I thought some of the folks comments may be of interest to you. Read 709 install article: www.irv2.com

  • The SeeLeveL recreational vehicle tank monitoring system has been, for quite a while now, the leading digital display system on the market. Other systems have been introduced, but none with the accuracy, features, and ease of installation of the SeeLevel. I’ve been such a fan of it that I have recommended it be installed in family and friends coaches as well have it in each of our previous motorhomes.  Here is an install of a 713 system on Joe Kasunich’s new Allegro Bus motorhome:  www.irv2.com

  • I am really excited to have an accurate reading of all my tanks this RV’ing season. Install article: www.irv2.com

  • An article from one of our customers who own a Tiffin Breeze, which is a small 30 ft. diesel pusher motorhome that is a newer design released in the past 5 years. Installing the SeeLeveL II Tank Monitor on a Breeze.

    —Anonymous, Satisfied Customer

  • The sensors themselves are trouble-free. No more fouling issues. … The information is very accurate and displayed on an easy-to-read LED panel. An easy DIY installation makes this an attractive upgrade for any RV owner who wants trouble-free accurate information, this upgrade easily makes our “A” list.  Read full article here.

  • Garnet Instruments uses external sensors and high-grade electronics to eliminate erroneous readings.  Read full article here.

  • For RVers like us that spend a significant amount of time off-grid dry camping having an accurate holding tank monitor with fine resolution is awesome. The new SeeLevel system has proved most useful, especially when it comes to fresh water levels. In my mind, it’s a crying shame that many new RVs still come with the cheap dummy light level indicators. Read the full review here. Watch the video here. (2017)
