    If SoCal 182 doesn’t buy it, pm me.

    I tried to transfer the STC on one of these a few years ago, and Horizon wanted a punitive amount ($500 IIRC -- for a $700 device). I'd call them for current information if buying for a certified aircraft.

    Buyer beware...

    Horizon makes a good tachometer, but be aware that it is incompatible with some electronic ignitions including Pmag, and Surefly.

    Even more concerning service. Very often, they will simply refuse to transfer the STC to another plane. If so, they charge an exorbitant amount like the poster above mentioned. Have had many customers run into this.

    Several years ago I replaced the engine in my RV-6. I wanted the Horizon tach reset to reflect new hours. It was a unit I had purchased, and being in an experimental there was no STC involved. I was quoted $320 plus shipping both ways.

    Again, it is a good product but they seem to just like to sell units and not deal with them after the sale.

    I came here to say what the last two guys did, pretty much... Once you've installed this in one certified airplane, they make it expensive and/or impossible to transfer it to a different certified airplane. Best bet is to sell it to someone with an experimental who is aware of its limitations with electronic ignition.

    I was thinking about one of these if my tach were to go bad. Glad I read this post, not going to happen with poor customer service after the sale. Wondering if you bought a new one would the manufacturer reset the tach time to what ever you asked them to, without additional charge?

    FWIW, I think I like the EI tach better if you're going that way: https://iflyei.com/product/r-1-rpm-tachometer-instrument/

    If you have a full-size (3 1/8") tach, what I like even better than that is their CGR-30 series: https://iflyei.com/product/cgr-30-combo/

    That's a great way to replace MP/RPM gauges and get a lot in return for a pretty reasonable price.

    Yes, if you purchase one new they program rpm limits and engine hours as part of the sale..

    FWIW, I called Horizon several times to inquire about reprogramming this unit for my plane. Nobody ever answered the phone or returned a message. They did not respond to emails, either. I simply gave up.

    We define reasonable rather differently. :) A $6,000+ primary multi-gauge to replace a $300 analog/$600 digital tachometer?

    To be fair, I linked to the "Combo" back which is two different units together: The "P" and "C" models. The "P" is primary for MP, RPM, EGT, CHT, and three additional items of your choice. The "C" gives you up to 16 additional gauges.

    So yeah, if you need a new tach anyway, and you want an engine monitor anyway, it's a nice way to kill two birds with one relatively (to its capability) reasonably priced stone. ;)

    Don’t these instruments fall under the “we don’t need TSO or STC” as they are minor changes at most? I know this is still an argument, mostly with radios and avionics.

    @weirdjim would you be able to just use “experimental” versions of these instruments?

    The official name of "we don't need TSO or STC" is NORSEE: NOn-Required Safety Enhancing Equipment. For example, an AoA would fall under that, as it's not required.

    The engine gauges, however, are required, so they need to be approved.

    Ok, so that means that I could install a non-certified (experimental) carb temp gauge or engine monitor as a logbook entry (if not replacing any primary instruments)?

    There was all the talk about how there is the possibility of installing a G5 with just a logbook entry, so certainly a carb temp gauge or even replacement tachometer would be similar.

    Neither of those instruments are required or originally equipped on a Cessna 150.

    But the real question is, just like radios, some of which never had an original TSO, did the primary instruments have any certification requirements that actually require an SAtC instrument to replace them? Or is the requirement simply that the airplane must have a Tachometer that “meets TSO” but is not required to “have a TSO” like the transponder is required to have.

    I know there are two sides, just wanted to hear @weirdjim weigh in on other instruments than radios and nav equipment as far as the STC requirement.

    A tachometer absolutely is required, and was equipped on a Cessna 150.

    A tach is required (duh, of course I know that), but do the regulations specifically state which type of replacement tach I must install? So can an AP replace the tach with an experimental model that “meets TSO” but does not have a TSO as a logbook entry?

    It has been argued and known that the only avionics that require a TSO are transponders and IFR GPS, not radios. So do replacement engine gauges have to have a TSO or just meet TSO? Or do they have to have an STC or can they just be installed by a minor mod logbook entry.

    And do engine gauges like carb heat and cylinder head temp fit the NORSEE guidelines? They are not required at all.

    Not an A&P, but I believe that since you're replacing factory equipment you need to replace it with either the same part number, a part that is specifically called out as equivalent, or something STCed.

    Whether or not they are required depends on whether the airplane was certified with them. On some planes, CHT is required... And despite it being a crappy single-cylinder needle-gauge CHT in many cases, even installing a full engine monitor with digital CHT on all cylinders doesn't replace the need for the factory original to be working *unless* you get an engine monitor that's certified as a primary source for CHT.

    I'm aware that it's dumb. I'm not going to argue that it's necessary. But, that's the way it is.
