Builders,
Thanks for bringing the matter of Fuel Mizer vs.
NavMan fuel computers to our attention. We have
carried Fuel Mizer for a couple of years and had never
heard of NavMan. We asked the manufacturer of NavMan
about the difference in the units, and as you can see
---From the following commentary there is definitely a
difference, only the Fuel Mizer is recommended for
Aviation use. Fuel Mizer has been thoroughly tested
in aviation applications and is certified for
CAO-95-45 aircraft in the Australia.
Best Regards,
Jim Irwin

Subject: Questions Regarding Fuel Mizer
Dear Jim:
I am forwarding an email I received from Ole Jensen,
President of Boss Products, the manufacturer of the
Fuel Mizer under license from Navman. SlipStream is
Boss Product's North American distributor. In his
response to the questions posed yesterday, he
references certain modifications and approvals
received for use of this product in aviation. The
exact language found on the cover of the Installation
and Instruction manual is as follows:
This instrument has been modified to comply with
Australian Engineering order HEO-469 and certified for
CAO 95-25 type aircraft in Australia.
Please let me know if you have any questions, or
desire any further information.
Kindest regards,
Mike Puhl
SlipStream International

Subject: Re: Mizer.
Dear Mike:
The question raised regarding the Navman fuel
flow meter and the Mizer is a common one that has been
around for many years and a lot of people have lost
money and endangered themselves by purchasing the
Navman for use in aviation. Nearly all the Navman
units purchased for this application have failed and
Navman refuses to replace them under warranty. Several
years ago we negotiated with Navman and paid a
licensing fee that enabled us to make the appropriate
modifications for use in aviation. In addition, the
Mizer has been registered with CASA (the equivalent to
your FAA) and certified by a qualified aeronautical
engineer. Boss Products paid to have the appropriate
modifications made for use in civil aviation, and
these modifications have been improved upon several
times since. As a result, the Mizer enjoys an
excellent reliability record and has been certified
according to CAO order no.HEO-469 as printed on the
cover of the installation manual.
Any one doubting the validity of our agreement
with Navman is free to contact the Vice President of
Navman in New Zealand, Mr. Mark Michell, and he will
verify these facts. Boss Products is the only company
in the world licensed to modify and distribute this
particular product. Unfortunately, some unscrupulous
marine dealers still offer the Navman for use in
unapproved applications despite the knowledge that the
manufacturer strictly prohibits this practice. Greed
and ignorance are usually the motivator. I can also
tell you that the price differences between the Navman
and Fuel Mizer are reasonably close, especially
considering the potential danger for misuse in a
non-approved aviation application. Further, I spoke
with Navman earlier today and was told that no one in
the U.S. is offering this unit for anywhere close to
US $99.00, and that the suggested retail price is US
$299.00, though they offer special MAP pricing from
time to time.
Hope this helps to clear up this issue. Please let me
know if I can be of further assistance in any way.
Regards,
Ole Jensen
President
